- I don't know what this is. Since it's in a subdirectory, I'd assume
- you can move it, since there's no gurantee where subdirectory-based
- files end up.

- The aaaaa.* files are for the "secret credits" screen. You can even
- delete them if you want to. (To see the credits, select the WPS
- desktop and type CTRL-ALT-O)

- I'd be really careful about these. Moving them about on a DOS system
- results in an unbootable disk. I don't know what OS/2 Boot Manager
- does with them, though.

- I wouldn't unfragment it, but if someone has experience indicating
- otherwise, go ahead.

- Isn't this the OS/2 boot sector? I wouldn't unfragment this.
- Besides, Boot Manager probably creates it or something when you do a
- BOOT /OS2

- These should be moveable. I've overwritten them a few times while
- upgrading the system. I don't think that would have worked if they
- had to be in a fixed location. (I renamed them and then copied the
- replacement in, so they used different sectors)

- I didn't think any DOS backup programs do this.
