Hi Kenneth--

    I don't have any occasion to do so.  I would copy such files to a
100 MB Zip diskette.  If you don't have a Zip Drive, there are "native
OS/2" utilities that will copy a large file to a spanned flock of
floppies.  IIRC, one such is a "freeware" IBM EWS program.  Also, there
is the latest version of PKZIP/PKUNZIP for OS/2 that will span a set of
floppies as it compresses the original files.

    Since I use command-line utilities for most file maintenance, I
would find it very difficult to inadvertently wipe out both the contents
of a directory and the directory, in a single operation.  But if I were
to do so, I would probably realize what I had done after a very short
interval, so I would remember the name of the top directory.  One of the
virtues of RESTORE is that if you use the "/S" switch, you can restore
all the subdirectories of the named original directory in the same
operation that restores that directory.

    This interchange has been a good example of why one should not
generalize on one's own practices to apply to another person.  I
apologize for attempting to answering your original post to me.

    Regards,
