關閉Moodle的個人專用檔案空間private files area

參考資料：https://docs.moodle.org/311/en/Private_files

moodle給每個用戶提供一個個人專用檔案空間，老師、學生存檔都非常方便。但是在測驗考試期間就變成了漏洞，怎麼將其臨時隱藏或關閉起來呢？

該功能對應的權限是：moodle/user:manageownfiles 和 repository/user:view

學生對應的角色是 student，將其moodle/user:manageownfiles 和 repository/user:view兩個權限禁用

Preventing access to Private files

If you don't wish to use private files on your site, you can prevent access as follows:

1. Log in as an admin and go to Site administration > Plugins > Repositories > Manage repositories and disable the Private files repository.
2. Go to Site administration > Users > Permissions > Define Roles and edit the authenticated user role.
3. Unset the capabilities moodle/user:manageownfiles and repository/user:view and save changes.

If you want teachers to be able to access private files but not students, then in addition to the above steps

1. Go to Site administration > Users > Permissions > Define Roles and create a new role to be assigned in the system context.
2. Allow the capabilities moodle/user:manageownfiles and repository/user:view and save changes.
3. Assign teachers this new role as a system role.
