Do exist a way in order to delete all share from a user?occ or other... thanks
All share or all files?
all share...that is, I have 3 users: admin, user1 and user2.
admin share 3 files with user1 and user2.
I would delete all share from user1, so user1 don't see the 3 admin's files but user2 see the 3 admin's files.thanks
You can just unshare the 3 Files in the Share dialog in the web UI of ownCloud.
Just click on the trashbin icon.
I kwon, but the files are not 3, but 1000... do an API exist?
Yes, there is the OCS Share API, see https://doc.owncloud.org/server/10.0/developer_manual/core/ocs-share-api.html#delete-a-share
The documentation comes with examples as well.
