Local movies (c://videos) are been deleted

Xibo Version 1.8.12
Windows Player 2 R200
My local movies are been deleted, they are local files (c://movies) they been setup using local path on Xibo. They work OK some time end then all displays start to show static images, we check our local files and they have been deleted. Please Help, why those are been deleted?
Thanks in Advance

Was c:\movies the directory you had setup Xibo to use as its local library? If so, it will remove any files that it hasn’t put there itself.

If you have other assets you want to load, they need to be somewhere else, or sent down from the CMS.
