I have some files that appear to be stranded. Not sure if they are
safe to delete or not.

<po_folder>\wpcsin\x0d05782.000 - file is 3.5 GB, dated Dec 18, 2012.
<domain1_folder>\mslocal\gwinprog\4\ - 7 files, two from 2008 and five
from 2010
<domain2_folder>\mslocal\gwinprog\4\ - 7 files from earlier this month

It doesn't seem normal for any of the above to still be there. I
would think they would've been cleaned up. Can I do it manually?
