Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
The embodiment of the invention is mainly applied to scenes of storing the same data files in electronic equipment such as computers, mobile terminals, servers and the like in a classified manner. Fig. 1 shows a schematic structural diagram of a file storage system according to an embodiment of the present invention. As shown in fig. 1, the system 100 includes: an ontology storage module 110, a reference file generation module 120, and a file management table 130.
The entity storage module 110 is configured to store a file entity of a file in a dedicated area when the file is imported into a file directory of the system, and generate a file identifier of the file and a storage path of the file entity in the file management table 130;
the cited file generating module 120 is configured to generate a cited file corresponding to the file in the file directory, and associate the cited file with a file identifier of the file;
the cited file generating module 120 is further configured to generate a new cited file corresponding to the file in a new file directory when the cited file is copied to the new file directory, and associate the new cited file with the file identifier of the file.
The special area is a specific storage space of a file body used for storing the file by the system, such as a hidden partition of a magnetic disk or a hidden folder of an operating system disk, so that a user cannot easily find the file body, and the situation that a quote file of the file is unavailable due to the fact that the user deletes the file body by misoperation is prevented.
The file management table 130 is used to record the storage path and the file information of the file body of the file corresponding to the file identifier of the file. The file information includes: file name, file rights, file type, file size and/or modification time, etc. The file identifier may be used to uniquely mark a file.
In an optional embodiment, the ontology storage module 110 is further configured to generate file information corresponding to the file identifier of the file in the file management table 130. Specifically, several fields, such as a file identification field, a file name field, a storage path field of a file body, a file authority field, a file type field, a file size field, and/or a modification time field, may be included in the file management table 130 for a file to record related information of the file. When generating the file identifier of the file, the storage path of the file ontology, and the file information, the ontology storage module 110 may write a specific value in the corresponding field.
The reference file is an index of the file and is associated with the file identifier of the file. In particular, the file identifier of the file may be included in the reference file. The reference file is not a copy of the file, and does not occupy a certain file storage space like a file body of the file, and the reference file can only include the file identifier of the file, so that the occupied storage space is small and can be ignored.
It should be noted that, in addition to the two reference files, the user may copy and generate more reference files in more different file directories to perform detailed classified storage management on the files. For example, for a video file a, a user can import the file in the time a folder, the body storage module 110 stores the file body of the file a in a dedicated area, and generates a file identifier 0001 of the file a and a storage path of the file body in the file management table 130, such as C: \ System \ RealFile \ 0001; the reference file generating module 120 generates a first reference file corresponding to the file a in the time a folder, and associates the first reference file with the file identifier 0001 of the file a, for example, writes the file identifier 0001 in the first reference file; when the user copies the first reference file to the place b folder, the reference file generating module 120 generates a second reference file corresponding to the file a under the place b folder, and associates the second reference file with the file identifier 0001 of the file a, for example, writes the file identifier 0001 in the second reference file; similarly, when the user copies the second reference file to the person c folder, the reference file generating module 120 generates a third reference file corresponding to the file a under the person c folder, and associates the third reference file with the file identifier 0001 of the file a, for example, writes the file identifier 0001 in the third reference file.
In an optional manner, the system 100 further comprises:
the positioning module 140 is configured to, when any of the cited files is opened, search the storage path of the file body in the file management table 130 through the file identifier of the file, position the file body of the file according to the storage path of the file body, and open the file body of the file.
Specifically, when the user needs to open any one of the reference files, for example, when the user opens the third reference file, the positioning module 140 finds the storage path C: \ System \ RealFile \0001 of the file body in the file management table 130 through the file identifier 0001 included in the third reference file, positions the file body of the file a according to the storage path, and opens the file body.
In an optional manner, the reference file generating module 120 includes:
a reference counting unit 121, configured to count reference files corresponding to the file identifiers, and record a reference counting result in the file management table 130.
Specifically, the file management table 130 is further configured to record a reference count result corresponding to a file identifier of the file. For example, a reference count field corresponding to the file identification of the file may also be included for the file in the file management table 130. The initial value of the reference count field is 0.
Correspondingly, the reference counting unit 121 is configured to, when a reference file corresponding to the file is generated in the file directory, add one to a value of a reference count field corresponding to a file identifier of the file in the file management table 130; the reference count unit 121 is further configured to, when the new directory generates a new reference file corresponding to the file, add one more to a value of a reference count field corresponding to a file identifier of the file in the file management table 130.
In the above example of the video file a, when the reference file generation module 120 generates the first, second, and third reference files, the reference count unit 121 modifies the values of the reference count fields corresponding to the file identifier 0001 into 1, 2, and 3 in the file management table 130, respectively.
In an alternative, the system 100 further comprises:
a deleting module 150, configured to delete any reference file, and after deleting the any reference file, adjust a reference count result corresponding to the file identifier in the file management table 130;
and if the adjusted reference counting result corresponding to the file identification is 0, deleting the file body corresponding to the file identification under the storage path.
Specifically, when a user deletes a reference file, the deletion module 150 deletes the reference file, and decreases the value of the reference count field corresponding to the file identifier by one in the file management table 130 according to the file identifier associated with the reference file; and if the value of the reference count field is 0, deleting the file body corresponding to the file identifier under the storage path.
In the above example, if the user deletes the first, second, and third reference files in sequence, the deleting module 150 deletes the corresponding reference files, and modifies the values of the reference count field corresponding to the file identifier 0001 to be 2, 1, and 0 in the file management table 130. When the deleting module 150 deletes the first and second reference files, the deleting module 150 does not delete the file body because the value of the reference count field is not 0, but when deleting the third reference file, the deleting module 150 judges that the value of the reference count field corresponding to the file identifier 0001 is 0, queries the storage path of the file body according to the file identifier 0001, and deletes the file body corresponding to the file identifier 0001 under the storage path.
Further, the deleting module 150 may clear all field records corresponding to the file identifier in the file management table 130 after deleting the file body corresponding to the file identifier.
In an optional manner, any of the file information of the reference file and the file body is the same and is a value of a file information field corresponding to the file identifier in the file management table 130; the system 100 further comprises:
a file information updating module 160, configured to, when the file information of any of the referenced files is changed, change the value of the file information field corresponding to the file identifier in the file management table 130 into the changed file information.
Specifically, when the user changes the file information of any reference file, the file information updating module 160 changes the value of the file information field corresponding to the file identifier associated with the reference file into the changed file information in the file management table 130 according to the operation of the user. As described above, the file information may include a file name, file authority, file type, file size, modification time, and/or the like. Taking the video file a as an example, when the entity storage module 110 generates the file identifier 0001 of the file a and the storage path of the file entity in the file management table 130, various file information of the file a may be generated, for example, a specific value is written in a corresponding field in the file management table 130, and one example is shown in table 1.
TABLE 1
| File identification | File name | Document body storage path | File type | File size | File rights | Modifying time | Reference counting |
| 0001 | A | C:\System\RealFile\0001 | video | 100MB | public | 11 months, 5 days, 18 hours and 12 minutes | 0 |
The file information of the three reference files and the file body of the file A are the same and are the values of the file information fields corresponding to the file identifier 0001 in the table 1. The file information in table 1 is displayed when the user views a certain reference file attribute. Subsequently, when the user changes the file information of one of the referenced files of file a, if the second referenced file is operated to change the file name to a1, the file information updating module 160 changes the value of the file name field corresponding to the file identifier 0001 associated with the second referenced file to the changed file name a1 in table 1 according to the user operation, and may update the value of the modification time field to 11 months, 6 days, 17 hours, 26 minutes. The file information of the remaining referenced files and the file body is updated to the changed file information in the file management table 130.
In an alternative, the system 100 further comprises:
the storage path updating module 170 is configured to, when the system 100 changes the storage path of the file ontology, change the value of the storage path field of the file ontology corresponding to the file identifier in the file management table 130 into the changed storage path.
Specifically, the storage path of the file body of the file is not easily changed, but in some special cases, if the disk storage space is not enough, the storage path of the file needs to be adjusted, the file storage system 100 may change the storage path of the file body, the storage path updating module 170 stores the file body of the file in the new storage path, and changes the value of the storage path field of the file body corresponding to the file identifier in the file management table 130 into the changed storage path. For example, for a video file a, the System 100 needs to store the video file a in a New dedicated area, the storage path updating module 170 stores the file body of the file in a New storage path C \ System \ RealFile \ New \0001, and changes the value of the storage path field of the corresponding file body into C \ System \ RealFile \ New \0001 in the file management table 130 according to the file identifier 0001 of the file a.
In summary, in the file storage system provided in the embodiment of the present invention, when a user imports a file into a file directory, a file body of the file is stored in a dedicated area, a reference file corresponding to the file is generated in the file directory and is associated with a file identifier of the file, and when the user copies the reference file into a new file directory, a new reference file corresponding to the file is generated in the new file directory, and the new reference file is associated with the file identifier of the file. Through the system, the file body is stored in the special area of the system under the condition that the same file is respectively stored in different file directories by a user, and only the reference file corresponding to the file is generated in each file directory without occupying the storage space, so that the file storage space is only occupied once for the same file, the waste of the file storage space generated by classified storage of the same file can be effectively reduced, the data redundancy is avoided, the classified storage management of the file is optimized, and a large amount of storage space is saved. In addition, the file storage system provided by the embodiment of the invention can be directly embedded into an operating system of the electronic equipment and directly run in the operating system, so that the classification management of the files by a user is facilitated, the files are not required to be checked, marked and classified by some special management software, the user operation is simplified, and the user experience is improved.
