Abstract

PROBLEM TO BE SOLVED: To set a file name as desired by a user by identifying the file while using file attribute information such as a registering person's name or a keyword when registering a file name for user to plural files. SOLUTION: Concerning a file name for system to be generated when registering the file, time information at that time point is used for the file name so that the existence of plural files having the same file name for system in one directory can be prevented (processing 103). Then, the file name for user and the file name for system are added to a managing file together with the file attribute information such as registering person's name or keyboard (processing 104). Thus, since the file name for user registered by the user and the file name for system to be used for a filing system for generating, writing and reading the file are applied to one file, the same file name for user can be registered to plural files.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file management method, and more particularly to an electronic file device, a video conference device having a file storage function, various media data can be stored as files, and transmission and reception of these files can be performed. The present invention relates to a file management method suitable for a multimedia communication terminal device to be executed.

[0002]

2. Description of the Related Art In a conventional word processor or electronic file device, or a device for generating and storing a file such as a personal computer or a workstation, a file name registered by a user is stored in a directory in which the file is stored. It was not possible to set the same file name as the file.

In general-purpose computers such as personal computers and workstations, a user creates a new directory having a hierarchical structure and manages files systematically, so that a single file system has many identical or similar file names. It is possible to exist.

[0004]

However, in a word processor or an electronic file device, a directory in which a user can save a file has no hierarchical structure.
In addition, the number is limited. If the directory in which the files are stored does not have a hierarchical structure and the number of directories is limited, as the number of files to be stored increases, the file names of files in one directory have similar file names. More. Therefore, the user must set the file name so as not to duplicate the existing file name, and it has been difficult to set the file name as desired by the user. In this case, when a user later searches for a file with a file name set by himself, there are many similar file names, so that there is a problem that it takes a long time to search for a target file.

As one method for solving this problem, file attribute information such as a registrant name and a keyword is managed in association with a file name, thereby improving the efficiency of file search. For example, in an "information search device" described in Japanese Patent Application Laid-Open No. 5-151264, search efficiency is improved by searching for a corresponding document and page number using a search keyword.

However, even in such a case, a plurality of files having the same file name cannot exist in one directory, and it is difficult to set a file name as desired by the user. .

In addition, when registering a file and registering a registrant name and a keyword as file attribute information together with a file name, the registrant name and the keyword are input one by one. There was a problem that it took time and the work was troublesome.

Accordingly, the present invention has been made to solve such a problem, and provides a file management method capable of setting a file name as desired by a user using file attribute information. The purpose is to do so.

Still another object of the present invention is to enable a user to easily read a target file even if there are a plurality of files having the same file name.

It is another object of the present invention to prevent files having the same file name from being given exactly the same file attribute information.

It is another object of the present invention to facilitate the operation of registering the file attribute information and reduce the burden on the user.

[0012]

According to a first aspect of the present invention, in a file management method of a file system having no directory hierarchical structure, a user file name registered by a user for one file is provided. And a file name for a system used by the file system to perform file operations such as file generation, writing, and reading, and the file name for the system is a file name that is not duplicated for each file. On the other hand, the file name for the user, the same file name for the user can be registered for a plurality of files,
When the same user file name is registered for a plurality of files, the file is identified using file attribute information such as a registrant name and a keyword.

According to a second aspect of the present invention, in the file management method of the first aspect, a file name for a user of a file selected by the user for reading is added to a plurality of files. If the file is a file, the file attribute information of the file is displayed on a display, and the file is read out by selecting one of the files by the user.

According to a third aspect of the present invention, in the file management method according to the first or second aspect, a set of a user file name and file attribute information which is input when a user newly registers a file. Is already attached to another file, prompt the user to change the file attribute information, and give the same file attribute information to multiple files with the same user file name This is to prevent it from being done.

According to a fourth aspect of the present invention, there is provided the file management method according to any one of the first to third aspects, further comprising a function of registering a plurality of user names and keywords. When registering a registrant name and a keyword as file attribute information in a newly created file, a plurality of user names and keywords registered in advance by using the registration function in the input operation of the registrant name and the keyword. Is selected and input from the list.

The data is transmitted to a remote terminal via 1MLP.

Next, a file management method according to this embodiment will be described. Directories in which users can store files have no hierarchical structure, and the number is limited. As the user directory, there is a directory corresponding to each medium for storing a file for each type of the medium, and a conference directory used during a communication conference. In addition, a predetermined number of directories that the user can freely use are prepared.

In a communication conference, a plurality of media files may be transmitted and received. In this case, a plurality of media files are mixed in one conference directory. The file is provided with a user file name registered by the user and a system file name used by the file system for generating, writing, reading, and the like of the file. The two file names are attributed to the file. It is registered in the management file along with the information.

One directory has one management file. The attribute information of the file registered in the management file includes the type of the medium, the name of the registrant, the keyword, and the like. It should be noted that the system file name uses the time information at the time of file registration as the file name, so that a plurality of files with the same system file name do not exist in one directory. In addition to the time information, for example, a random number or the like may be used.

First, the registration operation in the first embodiment will be described with reference to the flowchart shown in FIG. Here, an example in which two files having the same user file name exist in the directory for color still images will be described.

First, the process waits for a file registration operation to be performed (NO loop in decision 101). After the registration operation has been performed, it waits for the input of a user file name, a registrant name, and a keyword. (YES of judgment 101 → judgment 10
2 NO loop). Here, it is assumed that the user A has registered “design material 1” as a user file name and “new car X” as a keyword together with a registrant name in a directory for color still images. It is also assumed that another user B has registered "design material 1" as a user file name and "new car model Y" as a keyword together with a registrant name in the same directory (YES in decision 102). In this case, FIG. 4 shows user file names, system file names, media types, registrant names, and keywords registered in the management file. The system file name generated at the time of file registration uses the time information at that time as the file name so that one directory does not include a plurality of files with the same system file name (processing 1
03). Then, the user file name and the system file name are added to the management file together with file attribute information such as a media type, a registrant name, and a keyword (process 104). Since the media type of the file is selected by the user at the start of the registration operation, the media type is stored in the RAM 4 and registered in the management file when the registration is executed.

As described above, for one file,
Since the user file name registered by the user and the system file name used by the file system for generating, writing, reading, etc. of the file are given,
The same user file name can be registered for a plurality of files. This eliminates the need to change this file name even if the user file name input at the time of file registration is already registered in another file. In particular, when the number of files increases, the number of similar file names increases, and the naming of the file names becomes troublesome. However, this troublesomeness can be eliminated.

Next, a read operation according to the second embodiment will be described with reference to a flowchart shown in FIG.

First, the process waits for a file read (display) operation to be performed (NO loop in decision 201). When the file read operation is performed, a list of directory names is displayed on the LCD1.
5 (YES in decision 201 → process 202), and waits until a directory is selected (NO loop in decision 203). When the user selects a directory for color still images as a file to be read, the file names of the files existing in the directory are displayed on the LCD 15 as a list (YES in decision 203 → process 204), and the file is selected. (NO loop of decision 205). Note that the number of file names that can be displayed simultaneously is predetermined, and when the number of existing files exceeds this predetermined value, the file names are sequentially displayed by scrolling. The user selects “Design Material 1”
Is selected, the application program opens the management file in the directory for color still images and checks whether the same user file name exists in the file data (Y in decision 205).
ES → process 206 → decision 207). If it exists, the file attribute information of all the files in which “design material 1” is registered as the user file name is displayed on the display (YES in decision 207 → process 20)
8). This display example is shown in FIG. In FIG. 6, attribute information of two files having the same file name is displayed. When the user points to any of these display areas, the selected file is read, and a color still image is displayed on the CRT 19 (YES in decision 209 → process 21).
0). If there is no file having the same user file name, the content of the selected file is displayed (reproduced) as it is (NO in decision 207 → process 210).
Although the case of a color still image has been described as the media type of the file, the output destination of the read file data differs depending on the media type. For example, in the case of audio data, the output destination is the speed 11.

As described above, when the user file name of the file selected by the user for reading is given to a plurality of files, the file attribute information of those files is displayed on the display. The displayed file allows the user to easily read the target file.

Next, a case where a user newly registers a file (corresponding to claim 3) will be described with reference to a flowchart shown in FIG.

When the operation of registering the color still image displayed on the CRT 19 is performed, a screen for selecting a directory for saving a file is displayed (YES in the determination 301 → process 30).
2). Here, when a directory for a color still image is selected, an input screen for a user file name and file attribute information is displayed (YES in determination 303 → process 304).
Here, "File 1 of design" as a file name, "User A" as a registrant name, and "New car X" as a keyword
Is input, the management file in the color still image directory is opened, and it is checked whether or not the input data set exists in the file data (process 305 → determination 306). If the file already exists, a message prompting the user to change the user file name or file attribute information is displayed, and the screen returns to the input screen without registering the file (YES in determination 306 → processing 307 → processing 304). . Here, when the keyword is changed to "new car Z", it is checked whether or not the input data set exists in the file data of the management file in the same manner as described above (process 305 → judgment 306). If not, a system file name is generated, and the input data set is additionally registered in the management file in the color still image directory (NO in decision 306).
→ Process 308). Then, an encoding process of the color still image displayed on the CRT 19 is executed, and the compressed data is written in the generated file (process 309).

As described above, if the set of the user file name and the file attribute information that the user inputs when registering a new file has already been given to another file, Since the change of the attribute information is prompted, the same file attribute information is not given to a plurality of files having the same user file name. Therefore, the convenience of the file registration operation is improved.

Next, an embodiment of the present invention will be described.

By the way, in the case of the video conference apparatus, the seat position of each participant is stored before starting communication, and the participant name is designated when the direction of the TV camera 17 is moved, so that the participant can be designated. 2. Description of the Related Art A method of automatically changing the direction to the direction of a seat position has been conventionally implemented. When using this function, it is necessary to register the names and seat positions of each participant in pairs before starting conference communication. Here, if the name of the person using the video conference device is registered in advance when the device is installed, it is not necessary to register the name for each conference, which is convenient. This list of names is sorted and displayed, making it easy to search for names. With this name registration / search means, the above-described seat position registration work can be facilitated. In this embodiment, the name registered in advance is used. In addition, if a keyword, which is attribute information of a file, is written in the ROM 3 in advance, a file registration operation can be facilitated. That is, a general-purpose keyword predicted to be registered as attribute information of a file is selected and written in the ROM 3 in advance.

Regarding the above-described file registration operation using the previously registered name and the previously stored keyword,
This will be described with reference to flowcharts divided and shown in FIGS.

When the operation of registering the color still image displayed on the CRT 19 is performed, a screen for selecting a directory for saving a file is displayed (YES in the judgment 401 → processing 40).
2). Here, when a directory for a color still image is selected, an input screen for a user file name and file attribute information is displayed (YES in decision 403 → process 404).
Here, with the pen pointing to the input position of the registrant name which is the attribute information, with the cursor displayed at that position,
When the menu icon of “name list” is pointed with a pen, the list of names registered in advance when the apparatus is installed is sorted and displayed on the LCD 15 (YES in decision 405 →
Process 406). When the user selects his / her name from among them, the character string is displayed at the input position of the registrant's name (YES in decision 407 → process 408). When the user points the input position of the keyword, which is attribute information, with the pen and displays the cursor at that position, the menu icon of the "keyword list" is pointed with the pen to sort the keywords stored in the ROM 3 in advance. To display on LCD 15 (NO in decision 405 or processing 408 → decision 409)
YES → Process 410).

When the user selects one of them, the character string is displayed at the input position of the keyword (decision 41).
YES of 1 → process 412). When the user file name and the attribute information of the file selected as appropriate are input and the execution key is pressed, a system file name is generated, and the input user file name and the input attribute information are written in the management file. At the same time, the compressed color still image data is written in the generated file (decision 413).
YES → process 414 → process 415).

As described above, when the registrant name is registered as the file attribute information, the user name already registered by the user name registration means is used. When the keyword is registered as the file attribute information, the registrant name is already registered. Since the stored keywords are used, the operation of registering the file attribute information is facilitated, and the burden on the user can be reduced.

In the above description, the operation of handling a file of a color still image has been described. However, a file of another medium, that is, a file of a sound, a moving image, a facsimile image, and a drawing image is similarly processed. Is done.

[0048]

As described above, according to the first aspect of the present invention, in a file management method of a file system having no directory hierarchical structure, one file is registered for a user who registers the file. File name,
A file name for a system used by the file system to perform file operations such as file creation, file writing, and reading, and a file name for the system is provided for each file without duplication. On the other hand, the user file name can register the same user file name for a plurality of files, and if the same user file name is registered for a plurality of files, the registrant name Since a file is identified using file attribute information such as a file and a keyword, the same user file name can be registered for a plurality of files. Therefore, even if the user file name input at the time of file registration is already registered in another file, there is no need to change this file name, and the file name desired by the user can be set. . In particular, when the number of files increases, the number of similar file names increases, and naming of file names becomes troublesome. However, this troublesomeness can be eliminated.

Further, according to the second aspect of the present invention, in the file management method according to the first aspect, the user file name of the file selected by the user for reading is assigned to a plurality of files. If the file is read, the file attribute information of those files is displayed on the display, and the file is read out by selecting one of these files by the user.
In addition to the effect of the first aspect, there is an effect that the user can easily read out the target file.

According to a third aspect of the present invention, in the file management method according to the first or second aspect, the user inputs a user file name and file attribute information which are input when a new file is registered. If the set has already been assigned to another file, the user is prompted to change the file attribute information, and the same file attribute information is applied to multiple files with the same user file name. Since the file attribute is prevented from being added, in addition to the effect of claim 1 or claim 2, the same file attribute information is not added to a plurality of files having the same user file name. This has the effect of improving the convenience of the file registration operation.

According to a fourth aspect of the present invention, in the file management method according to any one of the first to third aspects, the file management method has a function of registering a plurality of user names and keywords. When registering a registrant name and a keyword as file attribute information in a newly created file, when inputting a registrant name and a keyword, a plurality of user names and Since any one of the keywords is selected and input, in addition to the effects of claims 1 to 3,
There is an effect that the operation of registering the file attribute information becomes easy and the burden on the user can be reduced.
