How to restrict users from deleting a file + How to get back a deleted file?


Pravin Patil (104138133) | asked Nov 02 '15, 9:09 p.m.
 Hi,

#1 - Is there a way to restrict users from being able to delete ANY files in component? I checked the "team configuration > Permissions" and it didn't have any.

#2 - Also, a user deleted a file and he doesn't recollect which component or workitem he used while deleting it. Is there a way to get this file back?

Please let me know.

1. I don't think you can prevent the users to delete a file and check-in from his workspace, but you can prevent him deliver that change set to the stream by using "Restrict Changes by Item Name" pre-condition in "Deliver Phase 2 (server)" operation behavior.

2. To restore the file, you have to know from which component and change set you made the deletion, then discard or reverse the change set.

This advisor code would be able to prevent delivery of deletions. It is from somewhere in the wiki. You can search for deletions. In general I do think that deletion is common enough that people should be allowed to do them.
