 Both will work.  One uses the command explicitly designed for
 it, and one accomplishes it by the back door.
GM> Uhmmm.  Very strange.
 I think my comment was a remnant of thinking that you were
 trying to save DESCRIPT.ION, not save a description it it.

 Odd.  I hadn't thought that DIR alone cleared orphans.
 Only deleting or moving seems to in some quick tests.

 Is the description the same everywhere?  Because if it is,
 it's probably easier to globally recreate it than preserve it.

 Personally, I wouldn't.  I'd just redescribe the file.
 That process would prune the DESCRIPT.ION file in the
 unlikely event there are duplicates.  Or one could do
 ffind /a:h /v /t"*anti-vir.dat*" descript.ion
 That gets you a full list.  You could redirect that to a file,
 and then grab the penultimate word on the last line of that file:
 %@word[-1,[%@line[$di,%@lines[$di]]]    for the number of appearances
