Set up a database OfficeFiles in SQL Server, and then set up a data table Physics in it. The field "Level" indicates whether the recorded information belongs to a folder or a file. If the value is 0, it means a file; otherwise, it means a folder, indicating what level of folder it is (for example, if the value of the "Folder" field is "Adult Education | Computer Application", the value of this field is 2).

The "Folder" field describes the logical absolute path of a file or folder (for the convenience of operation, a "|" separator is inserted between the folders of the path and at the end of the path, so the system does not allow "|" to appear in the folder name when users create a new folder or rename a folder); The file name field indicates the file name of the storage file.
