Where does the Files module store files?
1. Where does the Files module store files that the users upload?
2. How the file storage quota can be set by the Company level?
1. The location is /home/username/app_name/
app_name is either crossbox (unbranded) or the branded system_name (if white-labeled)
All files are stored under the user's dir so that the disk space used by the user can be calculated against the account's disk quota.
2. The storage quota for the company level is the same as the quota for that cPanel/Plesk/DirectAdmin/Standalone account.
This limit is set either by root or reseller.
