Usually, when a user works on a file; only that file gets engaged by the user but not others. However in some cases you may want nobody to work on that folder at all. In such a case, you can place a lock on the entire folder of suitable repository folder. A “lock” is also an “engagement”, but such an engagement is special as it is NOT based on actual use of a file. (Other possible engagements would be “CREATED”, “MODIFIED”, etc. which are based on actual file usage at that point in time)
Important
This can be a huge inconvenience to others. As when the entire folder is locked, as no other user can now work on any of the files here. If you do use this command, make sure that you remove all the engagements as soon as possible.
