You mix UNIX-Basics vs. suggested Application behaviour.

VDR could check the file mode. An when it is set 400, VDR could assume, then
it should not be deleted. So VDR would always skip this file. The question
of being available or not is irrelevant. Browsing manually in the recordings
directory and trying to delete such a marked file would invoke a confirm dialog.

This is a solution i would prefer. In this case I do not care about the
permissions and possiblities others have.

Bye... SP.
