An article was posted some time ago stating not to use DirWork 1.12
with the use of it causing the loss of data for a person. Thanks to
him I have worked out what happened and as some people asked here is
the situation.......
The problem occurs with all other directory utilities I have tested,
it is caused by a DOS bug. When a move operation is done on the same
device most intelligent programs do a rename so it happens very quickly.
So if you have a device with a dir ONE and another ONE/TWO and you do
the wierd operation of move ONE to ONE/TWO the program does
rename ONE ONE/TWO/ONE
DOS returns no error even though it stuffs up completely and the ONE
directory disappears so you lose all files/dirs that are decendants of
it. You can do it from DOS or from most if not all dir utilities.
I have not checked the situation with DOS 2.0 but doubt very much that
this bug remains in 2.0.
So DirWork 1.12 is not a Hard Disk muncher or anything of the sort as
might have been decided from the original article. It is just unaware
(as are sid 1.06 etc) of this DOS bug. A check for this very rare
situation will be included in the next version of course.

As the original poster of the article regarding a problem with DirWork 1.12, I also want to followup and confirm that everything is fine with DirWork 1.12. I apologize to the public, and the author, for any problems this may have caused. -- dean@coplex.UUCP Dean A. Brooks Copper Electronics, Inc. Louisville, Ky UUCP: !uunet!coplex!dean
