I have tried this procedure and but, did not get it to work.  We are
using
ADSM Server version 2.1.9 for AIX and Client version 2.1.6 for HP-UX.

A directory called "/test" was created with one file and one empty
sub-directory then a "dsmc selective -subdir=yes /test" was done.
A "dsmc q backup /test/*" showed only the file, the empty sub-directory
was not displayed.  A file was created in the empty sub-directory using
"touch /test/empty-dir/file" and then the file was removed to update the
sub-directory time stamp.  Next a "dsmc incremental -subdir=yes /test"
was done.  A "dsmc q backup /test/*" showed only the file, the empty
sub-directory was not displayed.

Can someone tell me if I have missed something.

Thanks
