Administrator task

I'm new to OwnCloud,

have installed it on debian created couple of users uploaded some files, as administrator I want to have list all files that I have been uploaded.
Activities from the users.
Where are the files saved

Where can i find this info

version 8.0.2

I will first recommend to use a newer version from ownCloud, 8.0.2 is really old. Probably 9.1.5 or 10.0.1

The files number form the administrator you can see with occ command, when you a files:scan or you can create a query in the database in the oc_filecache.

About to see the activities from other users, you need the Enterprise app: Log user and file sharing actions.
If you have the activity app you can see who reach your information that you shared with other users.
