How to design a set of naming rules for folders and files in office computers, so as to facilitate people in different departments to access information?

For secondary documents, it is best to use all departments of the company as folder names.

Three-level folders can be established according to different businesses of each department, such as the folder under the finance department, which can be divided into general ledger files, cashier files, cost files, current files and so on. The folders under the administration department can be divided into administrative files, logistics files, security files and even personnel files.

Under the three-level folder, it can be further subdivided as needed.
