I'm searching for a solution that allow on OwnCloud to lock files when necessary.
The scenario is the following: I'm going to use a file and I don't want that other users can modify that file during my editing. I'd like to have a mechanism that make me undestand that that file is being edited.
I've seen that for version 7 of Owncloud there was a File Locking App that seems to do this (https://doc.owncloud.org/server/7.0/admin_manual/configuration/files_locking_enabling.html)
Is there a solution for new version of OwnCloud (version 9.1).
