- I'd hardly call setting the hidden attribute 'proprietary' :-)

- The problem with using the undelete facility is that it makes file
- deletes much slower, particularly if you are deleting many small files (say,
- a couple of hundred icons). The time taken to delete a file seems to
- exponentially increase with the number of files sitting in the DELDIR.
- Of course, it may just be me that finds this a problem so I'd be glad to
- here about other peoples' experience with DELDIR and UNDELETE.
-
- BTW, I have a 486DX/25 (12Mb RAM) with a 10ms 245 IDE drive so I
- definitely think that this is a problem with OS/2 and not my hardware.
- I have no other performance related problems.
