Next, the technical solutions of the present invention are described with specific embodiments.

Example 1

Specifically, as shown in the schematic flowchart in Figure 1, this solution includes the following steps:

Step S100, judging whether the specified folder is modified;

In this embodiment, the editor needs to perform storage management on the read files, and in order to manage these stored files, it also makes two tables for these folders, one table is called the content table, as shown in FIG. 2 , the In the table, information is stored for each folder and the files in the folder. In the table, each data structure representing a folder saves the ID, name, parent folder index, stored folder and Files stored in folders. Among them, each folder is saved with its own name as a key. In the content table, there is no inclusion relationship between the data structures of each folder, but is simply enumerated and recorded in the data structure. Its parent folder and the subfolders stored in that folder.

The other table is the structure table, which organizes the data into a tree structure on the basis of the content table. Specifically, as shown in Figure 3, the figure shows that the first folder contains two subfolders, the second one is the second one. Folder and third folder, the second folder saves three sub-files, and the third folder saves one sub-file.

The structure table is displayed on the interface of the editor through hierarchy and structure, so that users can intuitively know the storage relationship between files. The table of contents will not be displayed on the interface.

When there is no folder or file at the beginning, there is no content in the above two tables. When the first folder is initialized, the information of the folder is stored in the content table, and then the information in the content table is stored in the content table. The data is tree-shaped and stored in the structure table.

To judge whether the specified folder has been modified, it is to compare the content of the current folder with the recorded content table. If it is found that the data information in a certain folder is different from that in the content table, it is determined that the folder has occurred. Modify operation.

Step S200, if a modification occurs, update the preset content table based on the content level information of the modified designated folder; the content level information includes: the name of the parent folder, the level and name of the subfolder, The level and name of the subfile.

When a modification operation occurs, the above content table needs to be updated. Specifically, the modification operation includes addition, deletion, copying and renaming. When corresponding modification operations occur, the data recorded in the content table will be changed according to these corresponding operations.

Specifically, when the deletion operation is performed, the specified folder will be found in the content table through the name of the folder to be deleted, and then the sub-files and sub-folders will be deleted in sequence according to the information in the specified folder, that is, According to the names of sub-files and sub-folders recorded in the specified folder, find these sub-files and sub-folders, and then repeat the above operations until there are no sub-folders or sub-files in the folder, and then start to delete them in order. Wait until the contents of the specified folder are deleted, and then delete the specified folder. If the folder has a parent folder, the information of the folder will be deleted from the parent folder. Update of table of contents.

When performing a renaming operation, first copy the existing content table to obtain a new content table, so that the original content table can be used as an index of the new content table; then determine the renamed file or folder in the new content table; based on Determine the location of the file or folder in the new content table; modify the content of the determined location to the renamed name; delete the existing content table.

When the copy operation is performed, the copied folder has its own name, and before that, the specified folder needs to be found in the content table through the name of the specified folder to be copied. The subfolders and subfiles of the file are copied to the specified location. Generally speaking, in order to distinguish the copied file from the original file, a renaming operation will be performed again, and the file ID will be incremented in sequence.

When adding an operation, it is similar to the initializing folder operation. After adding a new folder, the corresponding ID, name, parent folder index, subfolder and subfile data are saved for the folder in the content table. The data is saved in the table of contents.

Step S300, updating the preset structure table based on the updated content table.

After the content table is updated, the data is sorted into a tree structure according to the structure therein, and the sorted structure is then saved in the structure table to complete the data unification of the structure table and the content table.

Further, in addition to the above modification operations, there are also query and load operations.

Specifically, when performing a search operation, the content table is queried by the keywords entered during the query. Generally speaking, the query keywords are file names, and there is no hierarchical relationship between each folder in the content table, so It is easy to find the specified folder, and recursively according to the parent folder information in the folder, the storage location of the target file can be obtained, and the process of fast search can be realized.

When the user opens the editor and starts to load the file, the stored file information will be read into a preset file format, such as json file format, and then the file content will be saved to the content table and structure table, so as to To ensure the consistency of file data.

By establishing a content table and a structure table in the embodiment of the present application, the unification of folder data is ensured, and the structure of the content table is simple. Except for the information of the parent section folder stored in each file, there is no inclusion relationship between the folders, which is convenient for In addition to the content data of each folder, the structure table also saves the mutual inclusion relationship between folders in a tree structure for query addition and deletion operations inside the program, so that users can clearly understand the file storage structure according to the structure table, and then carry out Subsequent actions edit.
