Question : Cannot delete all files from search

Hello -

Has anyone noticed this.  Looking for files in search.  Search comes back with say 10 files.  You selecting all files and trying to delete.  The errror comes back saying you cannot delete from the source of the disk or something.  However, they can be deleted individually one-by-one.
What causes that?

Thanks.

Answer : Cannot delete all files from search

The files being listed may be part of a compressed folder.
