>>> How can we limit the number of times a particular sub user can download a prticular file in a week ?
When you share a folder, you can specify an expiration time. However, the system does not limit the number of times a user can download a file.
If you have to limit the number of download times, you can:
(1) Create a sub-account and allocate a small amount of download bytes and storage space;
(2) From the Group Admin account, you can directly log on as the sub-user;
(3) Upload (copy) the file to a folder in the sub-account, then share the folder to other users.
This way, the max number of download times is determined by the file size and the sub-user's max download bytes. As the group owner / admin, you can re-allocate storage space and download bytes at any time.
