Description

  The present invention relates to a file name change management system and a file name change management program for managing file name changes.

  File names recorded on conventional computers can be freely changed except for restrictions such as prohibiting the use of reserved characters such as “*” and “?” And prohibiting duplicate file names in the same folder (directory). It was possible to do.

  Further, when restrictions such as reading and writing can be set for each file or folder, it is possible to limit whether or not the file name can be changed based on the user authority set for each file or folder.

There is also a data file monitoring device that monitors a specific data file stored in an information processing device such as a personal computer and prevents the data file from being tampered with. The data file monitoring device includes a file content change prohibiting unit that prohibits a change of the file content of the data file, and a file attribute change detecting unit that detects a file attribute change process of a read-only file whose file attribute is stored in the computer. And a file attribute read-only setting means for changing the file attribute to read-only again when the file attribute change detecting means detects a change in the file attribute of the monitored file, and the file attribute is set to read-only. The processing such as movement, deletion, and file name change of the monitoring target file is stopped (see, for example, Patent Document 1).
JP 2007-188307 A

  However, the change of the file name can be restricted by the reserved characters prohibited to be used, user authority, file attributes, etc., but these need to be defined and set in advance. In addition to these restrictions, the file names can be changed freely, and it is difficult to understand the relationship between files only by the file names.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a file name change management system and a file name change management program that can easily manage file relevance and can be easily managed.

The file name change management system according to the present invention is a file name change management system for managing the name change of a target file from a current name to a new name, and an operation information recording unit for recording operation information for a file in a computer, Base file specifying means for specifying the base file of the target file from the operation information, correction degree acquiring means for acquiring the correction degree between the target file and the base file, obtaining the allowable range of the name change based on the correction degree, and the new name The file name change management system includes a name change determination unit that determines whether the change is within the allowable range from the name of the base file, and a control unit that controls based on the determination result.
The file name change management program according to the present invention includes an operation information recording unit for recording operation information for a file in a computer, and manages a file name change management system for managing a rename of a symmetric file from a current name to a new name. A file name change management program that functions as a base file specifying means for specifying a base file of a target file from operation information, a correction degree acquiring means for acquiring a correction degree between the target file and the base file, a correction degree A file that functions as a name change determination unit that obtains an allowable range of name change based on the name and determines whether the new name is a change within the allowable range from the name of the base file, and a control unit that controls based on the determination result It is a name change management program.

  As a result, when a rename operation of the target file is detected, operation information that is a derivation base of the target file is extracted from the operation information recording unit, and the base file is specified from this operation information. The information related to the base file and the information related to the target file are compared to acquire the degree of correction. For example, when the degree of correction is large, the allowable range for the name change is increased. On the other hand, when the degree of correction is small, the allowable range is decreased. Then, it is determined whether or not the new name of the target file is included in the change within the allowable range of the name change from the name of the base file. Thereby, the name change of the target file is controlled according to the degree of correction from the base file, and the relationship between the target file and the base file can be easily determined from the file name. Further, since the names of all files derived from the base file are limited based on the base file, for example, the names of files having a small degree of correction with the base file are related to each other. Thereby, not only the relationship with the base file but also the relationship between files derived from the base file can be predicted by the file name. Furthermore, if the name change of a file is controlled according to the degree of correction with the base file, it is not necessary to set control details of the name change in advance, and management of the name change becomes easy.

  A synonym recording unit that records synonyms, and a word extracting unit that extracts a word from the name and new name of the base file, and the name change determination unit refers to the synonym recording unit, The word of the name may be compared, and based on the comparison result, it may be determined whether the new name is a change within the allowable range from the name of the base file.

  As described above, the file name change management system and the file name change management program according to the present invention are controlled in accordance with the degree of correction with the base file, so that the relevance of the file is easily understood. You can easily manage name changes.

  Next, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings. A file name change management system (hereinafter referred to as a management system) 1 of the present invention monitors a name change of a target file according to the relevance of the target file to be renamed from the current name to the base file. It is.

  As shown in FIG. 1, the management system 1 includes an operation information acquisition unit 4 that acquires operation information representing a user operation on the computer C, an operation determination unit 6 that monitors a name change based on the acquired operation information, and operation information. The operation information recording unit 5 that records the operation information acquired by the acquisition unit 4, the base file specifying unit 7 that specifies the base file of the target file from the operation information of the operation information recording unit 5, and the degree of correction between the target file and the base file Based on the correction degree acquisition means 10 to be acquired, the name change determination means 11 that acquires the allowable range of the name change based on the correction degree, and determines whether the new name is within the allowable range from the name of the base file, and the determination result A control means 12 for controlling the control and an execution means 13 for executing the control according to the control. The management system 1 functions as each unit by installing a file name change management program (hereinafter referred to as a management program) 2 in the computer C. Each means may be realized by hardware or software.

  The computer C includes a processing unit, a recording unit R, an input unit 3 and a display unit, and performs a calculation according to a program. The computer C may be composed of, for example, one or a plurality of terminals, or a server / client system. The server may be configured with a client terminal. The processing unit is a CPU that controls each device, calculates and processes data, and the recording unit R is a device that records information, a program, and the like, and temporarily stores an external recording device such as a hard disk and information. Includes a semiconductor recording device for recording. The input unit 3 is an input device that inputs characters or designates a file to operate the computer C. For example, the input unit 3 is a pointing device such as a keyboard, a mouse, or a touch screen. The display unit has an operation screen and displays files and the like recorded in the recording unit on the operation screen.

  The operation information acquisition unit 4 acquires operation information, stores the operation information in the operation information recording unit 5 and transmits the operation information to the operation determination unit 6. The operation information includes information indicating a notification or a request generated by a user operation or an application instruction using the input unit 3 or the like in the terminal, information indicating a history of processing executed by the terminal according to the notification or request, and the like. The operation information includes, for example, an operation process type, an operation process target, and date / time information. The processing type of the operation is the content operated by the user using the input unit 3 or the like and the content executed or executed in the terminal, and includes information such as “name change”, “copy”, “delete”, etc. is there. The operation processing target is information for identifying a target such as a file that has been operated and processed according to the processing type of the operation, and is file identification information such as a file name including a current name and a new name, for example. Note that the current name is a name that the target file to be renamed currently has, and the new name is a name specified by input by the input unit 3 to change the name of the target file. A file is a record of data and includes folders, applications, and the like. Furthermore, the file may be stored in the computer C, or may be stored in an external recording device, another terminal, or a server. The date and time information represents the operation time, and is information such as the date and time when the operation information is generated. Further, the operation information may include terminal identification information for identifying the terminal on which the operation has been performed, and user identification information for identifying the login user of the terminal.

  The operation information recording unit 5 records the operation information acquired from the operation information acquisition unit 4.

  The operation determination unit 6 determines whether the processing type of the operation information acquired from the operation information acquisition unit 4 corresponds to a name change. When the processing type corresponds to a name change, the operation information for the name change is transmitted to the base file specifying means 7. On the other hand, when the processing type does not correspond to the name change, the determination result is transmitted to the control unit 12 and the control content based on the determination result that the processing type does not correspond to the name change, for example, the operation information processing such as copying and deletion is executed. The control means 12 instructs the execution means 13. Here, the name change is a file name change that changes the name of the file from the current name to a new name, a file that is saved as a file that is different from the file with the current name, and that a new name is added to the file. For example, add and save.

  The base file specifying unit 7 specifies the target file from the operation information of the name change acquired from the operation determining unit 6, and specifies the base file of the target file based on the operation information recorded in the operation information recording unit 5. The base file operation information and the name change operation information are transmitted to the correction degree acquisition means 10.

  Specifically, the current name of the target file is specified from the processing target included in the operation information for changing the name, and date / time information is acquired from the operation information. Based on the current name and date / time information of the target file, the operation information of the derivative base related to the current name of the target file is extracted from the operation information recording unit 5 before the name change of the date / time information. The base file is specified from the extracted operation information, the operation information is acquired, and the operation information of the base file is obtained. Then, the base file operation information and the name change operation information are transmitted to the correction degree acquisition means 10. Here, the derivation group file includes a file having the current name, and in addition to this, if the file has been renamed or copied, it can include a file before being renamed or copied. The base file is a predetermined or arbitrary file of the base file derived from the target file.

For example, as shown in FIG. 2A, a case will be described in which the target file is being renamed from the current name “A _n-1 ” to the new name “A _n ”. First, on September 2, 2004, a new customer information file “A ₀ ” storing one customer information list is created, and on November 10, 2004, this file is converted from “A ₀ ” to “A ₁ ”. The file “A ₁ ” with the customer information added and the number of lists being 35 on March 25, 2005 is overwritten and saved. Next, after repeating operations such as adding customer information, saving overwriting, and renaming, overwritten the file “A _n-1 ” with customer information added up to 80 lists on June 27, 2008. saved. Next, after adding customer information on July 2, 2008 to 100 lists, _let 's save the new name “A _n ” to the target file with the current name “A _n-1 ”. It is said.

As shown in FIG. 2B, the date / time information “20080702” and the current name “A _n-1 ” of the target file are identified from the operation information of this name change, and the date / time information is before July 2, 2008. And the operation information whose processing target is the current name “A _n-1 ” and the names “A _n-2 ”... “A ₁ ”, “A ₀ ” derived from the current name are stored in the operation information recording unit 5. Extract from As a result, as shown in FIG. 2C, the operation information of the derived group indicating the contents of the operation on the target file “A _n-1 ” before the name change on July 2, 2008 is extracted. To obtain operation information of an arbitrary or predetermined base file. In addition, after acquiring the operation information of all the derivation groups from the operation information recording unit 5, the operation information of the base file is extracted from the operation information recording unit 5. However, the present invention is not limited to this. In addition, only the operation information of the base file can be acquired from the operation information recording unit 5 based on an arbitrary or predetermined extraction condition.

In this case, the target file is each file before the rename, that is, the file “A ₀ ” newly created on September 2, 2004 to the file “A _n-1 ” overwritten on June 27, 2008. Is a file derived from Therefore, the derivation base files of the target file are these files “A ₀ ” to “A _n-1 ”, and the base file of the target file is any or a predetermined file among the derivation base files. The predetermined file may be a file of a predetermined date and time, a file a predetermined number of days ago, the oldest file “A ₀ ”, a newly created file “A ₀ ”, or a predetermined operation from a name change. The file may be the file before the number of times, or may be the file “A _n-1 ” of the operation immediately before the name change.

  The modification degree acquisition means 10 receives the operation information of the base file and the name change operation information from the base file specifying means 7, compares the information about the target file with the information about the base file, and acquires the degree of correction. Then, the modification degree, the base file operation information, and the name change operation information are transmitted to the change determination unit 11. Here, the degree of correction is the similarity or difference between the base file and the target file. For example, if the change from the base file to the target file is small, the relationship between these files is strong and the correction level is small. For example, it is a single or plural combination of elements such as the amount of correction of the target file with respect to the base file or the number of corrections from the base file to the target file. The amount of correction of the target file with respect to the base file is a difference in data capacity, the amount of difference in data contents, and the like, and the number of corrections from the base file to the target file is the number of operations and the number of overwrites.

  In the case of the modification amount of the target file with respect to the base file, the modification degree acquisition unit 10 acquires the name of the base file from the operation information of the base file, and acquires a file recording unit (not shown) or file based on the base file name. A base file or its attribute information is acquired from a section (not shown). Also, the current name of the target file is obtained from the name change operation information, and the target file or its attribute information is acquired from the file recording unit (not shown) or the file acquisition unit (not shown) based on the current name. To do. Then, the contents, attribute information, and the like of the base file and the target file are compared, and a correction amount such as a difference in data capacity, a difference amount in data contents, and a ratio thereof is obtained. The file recording unit may be in the computer C, or may be outside the computer C such as a server, an external recording unit, or another terminal. In addition, the file recorded in the file recording unit may be a file such as a backup file that is saved by copying data. The file acquisition unit is in the computer C and acquires a file and its attribute information from a file recording unit outside the computer C.

  As another method, when the operation information has attribute information, the modification degree acquisition unit 10 acquires the attribute information of the base file from the operation information of the base file, and acquires the attribute information of the target file from the operation information of the rename. Acquire and compare the attribute information for the base file and the target file to obtain a correction amount such as a difference in data capacity or a difference in data content. The attribute information is information inherent to the file such as data capacity, data contents such as the number of customer information lists, and the like.

In the example of example 2 (a), when a file group file newly created "A _0", lists the number of groups file "A _0" is 1, the number of lists of the target file "A _n-1" Since there are 100 cases, the data content difference amount is 99 cases with respect to the data content capacity of 100 cases of the target file, and the correction degree is 99%. If the base file is the file “A _n-1 ” immediately before the name change, the number of lists of the base file “A _n-1 ” is 80. The amount of correction is 20% for 20 items.

In the case of the number of corrections of the target file with respect to the base file, the correction degree acquisition unit 10 acquires the operation information of the name change and the operation information of all the derived base files including the base file from the base file specifying unit 7. Then, operation information including date information is specified between the date information of the name change operation information and the date information of the operation information of the base file, and the number of corrections is calculated from the number of these pieces of operation information. In the case of FIG. 2A, if the base file is the file “A _n-1 ” on June 27, 2008, the date and time of the base file “June 2008” will be changed from the date and time of the name change “July 2, 2008”. Since there is no operation information included up to “27th”, the number of corrections is 1, and the correction level is 1. In this case, the number of operations is set as the number of times of correction. However, the number of times of operation is not limited to this, and the number of times of overwriting can be used. The modification degree acquisition unit 10 obtains the operation information from the base file specifying unit 7 and obtains the number of corrections based on the operation information. The base file specifying unit 7 calculates the number of operation information, and the number of the operation information. Can be received from the base file specifying means 7 as the number of corrections.

  The name change determination unit 11 acquires the correction level, the base file operation information, and the name change operation information from the correction level acquisition unit 10, acquires the allowable range of the name change based on the correction level, and acquires the new name of the target file. Is within the allowable range from the name of the base file, and the determination result is transmitted to the control means 12.

  The relationship between the correction degree and the allowable range is determined in advance by a predetermined standard such as an expression or a table representing them. For example, as shown in FIGS. 5A and 5B, the smaller the degree of correction, such as the amount of correction or the number of corrections, the higher the possibility that the target file matches from the base file, and these files are related. Therefore, the name change allowable range is set so that the name change amount from the name of the base file to the new name becomes small. This allows a change from the base file to a near name, and the new name is similar to the name of the base file, so these names are related. On the other hand, the higher the degree of correction, the more likely the target file is to be different from the base file, and these files are less related.Therefore, the name change is made so that the amount of name change from the base file name to the new name becomes large. An acceptable range is set. This allows a change from the base file to a different name, and the new name is different from the name of the base file.

  In the example shown in FIG. 4A, the base file name “license management table” is specified from the base file operation information, and the new name “software management list” of the target file is specified from the name change operation information. When these are compared, since 9 characters out of 11 characters in the new name of the target file are dissimilar to the name of the base file, the name change rate from the name of the base file to the new name is 82%. Referring to the predetermined standard showing the relationship between the correction degree and the allowable range shown in FIG. 5A, if the correction degree is 75% or more, the allowable range is 80% or more, and the name change ratio and the allowable range are compared. The name change ratio is included in the allowable range, and it is determined that the new name is a change within the allowable range from the name of the base file. On the other hand, if the correction degree is less than 70%, the allowable range is less than 80%, so the name change ratio is not included in the allowable range, and it is determined that the new name is not a change within the allowable range from the name of the base file. .

  Although the name change is determined based on the allowable range according to the correction amount, the present invention is not limited to this, and it is also possible to determine whether the number of corrections, the correction amount, and the correction frequency are within the allowable range in combination. Good.

  The control unit 12 receives the determination result of the name change determination unit 11 and controls the computer C based on the determination result. As the control content, for example, if the determination result is that the new name is a change within the allowable range from the name of the base file, the name change is permitted. Also, if the new name is a judgment result that is not within the allowable range from the name of the base file, the name change is invalidated or a warning indicating that the name cannot be changed or the allowable range for the name change is displayed on the operation screen of the display unit. Control. When receiving a determination result that the operation information is not a name change from the operation determination unit 6, the control content such as permitting the operation information is determined and transmitted to the execution unit 13.

  The execution unit 13 executes the control content of the control unit 12, and executes, for example, the name change of the target file according to the control content, rejects the name change, or displays a warning.

  Next, an example of the processing flow of the management system 1 and the management program 2 will be described based on the flowchart of FIG.

  When the operation information acquisition unit 4 acquires operation information obtained by operating the input unit 3 (S1) and transmits the acquired operation information to the operation information recording unit 5 and the operation determination unit 6, the operation information recording unit 5 acquires the acquired operation information. The information is recorded (S2), and the operation determination unit 6 determines whether the processing type of the acquired operation information is a name change (S3). When the name is not changed, the determination result is transmitted to the control means 12, and the control means 12 transmits control contents such as invalidating the name change of the target file to the execution means 13 based on the determination result. Executes control (S5). On the other hand, when the processing type is a name change in step 3 (S3), the operation determination unit 6 transmits operation information for the name change to the base file specifying unit 7, and the process proceeds to step 4 (S4).

  In step 4 (S4), the base file specifying means 7 specifies the target file and the name change time from the name change operation information, and determines the base file operation information based on the current name and date / time information of the target file. By extracting from the recording unit 5, the base file is specified. Then, the name change operation information and the base file operation information are transmitted to the correction degree acquisition means 10.

  The correction degree acquisition unit 10 acquires the current name of the target file from the operation information of the name change, and acquires the name of the base file from the operation information of the base file. Based on these names, information on the file such as the file and its attribute information is obtained from the file recording unit and file acquisition unit, etc., and these are compared, and the correction amount between the base file and the target file is acquired as the correction level. (S6). Then, the degree of correction, name change operation information, and base file operation information are transmitted to the name change determination means 11.

  The name change determination means 11 obtains an allowable range from the correction degree using a relational standard that defines the correction degree and the allowable range of the name change as shown in FIGS. 5 (a) and 5 (b). Further, the new name of the target file is specified from the operation information of the name change, and the name of the base file is specified from the operation information of the base file. The new name and the name of the base file are compared, and the name change ratio is calculated. The name change ratio is compared with the allowable range, and it is determined whether the new name is within the allowable range from the name of the base file depending on whether the name change ratio is included in the allowable range (S7). Then, the determination result is transmitted to the control means 12.

  The control unit 12 determines the control content according to the determination result, transmits the control content to the execution unit 13, and the execution unit 13 executes the control content. For example, if it is a determination result that the new name is a change within the allowable range from the name of the base file, the control content permitting the name change is transmitted to the execution unit 13, and the execution unit 13 inputs the input unit 3. The name of the target file is changed to the new name input from (S8). On the other hand, if the determination result is that the new name is not a change within the allowable range from the name of the base file, the name change is invalidated and the control content to be displayed as a message is transmitted to the execution means 13. Displays an error message indicating that the name cannot be changed (S9).

In this way, if the degree of correction from the base file to the target file is small, and the contents of the base file and the target file are similar and the relationship is large, the allowable range for renaming is the difference between the base file name and the new name. By being limited to be smaller, the new name of the target file is similar to the name of the base file. On the other hand, if the degree of correction from the base file to the target file is large, the contents of the base file and the target file are different and the relevance is small, the difference between the base file name and the new name is increased, for example, 90 If the name change range is set to more than%, name change is not permitted unless 90% or more of the new names are dissimilar to the name of the base file, and the allowable new name is the name of the base file. It will be different. Thereby, the relationship with the base file can be easily determined from the file name.
In addition, when file name changes are managed as described above, the names of all files derived from the base file are limited by the relevance of the base file. Are similar, and the relationship between files derived from the base file can be predicted by the name of the file.

  As shown in FIG. 6, the management system 1 of the second embodiment of the present invention is substantially the same as the management system of the first embodiment, except that the name change determination unit 11 includes the word extraction unit 8 and the synonym recording unit 9. It has different points. The description of the same parts as those in the first embodiment is omitted.

  The name change determination unit 11 includes a word extraction unit 8 and a synonym recording unit 9. The base file name and the current name of the target file are specified from the base file operation information and the rename operation information, respectively, and these are passed to the word extraction unit 8, and the name of the base file extracted by the word extraction unit 8 The word and the word of the current name are referred to the synonym recording unit 9 to compare whether or not these are synonyms, and whether or not the new name is within the allowable range from the name of the base file is determined based on the comparison result. .

  The word extraction means 8 extracts words from the name of the base file and the current name by using a method such as referring to dictionary data or a method of writing.

  The synonym recording unit 9 is a dictionary in which words having similar meanings are recorded. For example, “software”, “application”, “program”, “file”, and the like are recorded as similar terms. Further, a plurality of words having similar meanings can be recorded as a synonym group, and words in the same group can be used as synonyms.

  In the example shown in FIG. 4B, the name “client information XXX” of the base file is specified from the operation information of the base file, and the new name “customer information XYZ” of the target file is specified from the operation information of the name change. When the word extraction means 8 extracts words from the identified names and compares these words with reference to the synonym recording unit 9, the “customer” and the “client” are similar, the “information” is the same, and “XYZ” "Is not similar to" XXX ", one of the three new names of the target file is dissimilar to the name of the base file. Therefore, the name change ratio from the name of the base file to the new name is 33%. Then, referring to the relationship standard between the correction degree and the allowable range shown in FIG. 5A, if the correction degree is 25% or more and less than 50%, the allowable range is 20% or more and less than 50%. By comparing the ratio and the allowable range, the name change ratio is included in the allowable range, and it is determined that the new name is within the allowable range from the name of the base file. On the other hand, if the degree of correction is less than 25% and 50% or more, the allowable range is less than 20% and 50% or more, and the name change ratio is not included in the allowable range, so the new name is allowed from the name of the base file. It is determined that it is not within the range.

  Although the name change is determined based on the allowable range according to the correction amount, the present invention is not limited to this, and it is also possible to determine whether the number of corrections, the correction amount, and the correction frequency are within the allowable range in combination. Good.

  As shown in FIG. 3, an example of the processing flow of the management system 1 and the management program 2 will be described. In addition, description about the same part as 1st Embodiment is abbreviate | omitted.

  In step 7 (S7), the name change determination means 11 specifies the new name of the target file from the operation information of the name change, and specifies the name of the base file from the operation information of the base file. From the new name and the name of the base file, the word extraction unit 8 extracts a word, and the name change determination unit 11 refers to the synonym recording unit 9, and each of the word of the new name and the name of the base file is similar. The name change ratio is calculated by comparing whether or not to do so. Whether the new name is within the allowable range from the name of the base file is determined based on whether the name change ratio is included in the allowable range.

  In the above embodiment, the name change determination unit 11 may have a variable part recording unit (not shown) instead of or together with the synonym recording unit 9. The variable part recording part is a list or the like in which a part where the name change is allowed regardless of the allowable range of the name change is recorded. For example, the variable part does not represent the contents of the file such as date and version, but is attached to identify the file. In this case, the name change determination unit 11 refers to the variable part recording unit, and the word of the new name “customer 20070101” and the name of the base file “customer 200800811” of the target file extracted by the word extraction unit 8 are found. It is determined whether it is a variable part, and among these names, “20070101” and “2000081231” are determined as variable parts. Then, it is determined whether or not the word “customer” that is not the variable part matches or is similar. Since these match, the name change ratio between the new name and the name of the base file is calculated as 0%. Whether the new name is within the allowable range from the name of the base file is determined based on whether the name change ratio is included in the allowable range. When changing the date, the change from the date of the name of the base file to the date of the past may be included in the restriction, that is, the name change ratio.

  In the above-described embodiment, the word extraction unit 8, the synonym recording unit 9, and the variable unit recording unit are provided in the name change determination unit 11. However, the present invention is not limited to this, and the name change determination is performed on these units and recording units. It can also be provided separately from the means 11.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention.

  In all of the above-described embodiments, all the operation information is transmitted and acquired for the exchange of information between the respective means. However, the present invention is not limited to this. For example, it is necessary for subsequent processing such as the file name and its attribute information. It can also be information only.

  In all of the above embodiments, the relationship between the degree of correction and the allowable range of name change is set regardless of the number of characters in the name of the base file. However, the smaller the number of characters, the larger the name change rate is even for one character difference. Therefore, according to the number of characters of the name of the base file, it is possible to set a predetermined standard or condition indicating the relationship between the degree of correction and the allowable range of name change.

  In the relationship between the degree of correction and the name change, the allowable range is set so that the amount of name change increases as the degree of correction increases, but the present invention is not limited to this. For example, in FIG. 5A, the larger the correction degree, the wider the allowable range. For example, the correction degree can be set to 75% or more and the allowable range to 100% or less. Moreover, although the name change ratio from the name of the base file to the new name was determined, the present invention is not limited to this, and a name change amount such as a difference between the name of the base file and the new name can be used.

  Furthermore, in all the embodiments described above, the control contents are permission of name change, invalidity of name change, warning display, etc., but are not limited to this. For example, a warning display can be displayed, mailed, or notified on a terminal used by the user, a terminal managing the terminal, other terminals, a server, or the like.

  In all the above-described embodiments, the management system 1 and the management program 2 include the above-described units, the input unit 3, and the like in one computer C, but may be configured by a plurality of computers. For example, a single or a plurality of client computers and a server computer are configured to be communicable via a network, and the server computer includes an operation information acquisition unit 4, an operation information recording unit 5, an operation determination unit 6, a base file specifying unit 7, All or part of the correction degree acquisition unit 10, the name change determination unit 11, and the control unit 12 may be provided.
