“Optimize” from JWT Enterprises just makes files all use one segment. It does nothing for fragmented free space. It’s safe. All it’s really doing is:

1. open source file.
2. get size of source file.
3. create new file “_o” and set size to source file size (OS-9 makes it one segment).
4. read all of source file and write it in to destination.
5. delete source file.
6. rename “_o” to source file name.

OS-9 can be asked to create a file of $FFFF bytes, and it will return that in one segment if available. Very safe.

File System Repack from Burke & Burke is what I am running now, on a backup, just to see how it works on 128MB. His “cbm” Compress Bitmap program crashes, printing out garbage. I was fearing that Repack would have the same problems, but I ran it one one pass, and dcheck shows the file system is still intact. Maybe…
