I think Graham Utilities? Or FATOPT.exe from FM/2 (File Manager) Utilities.
Why would you use FAT anyway? HPFS is the native OS/2 file system, it works so much better. Really!

That certainly is a matter of opion. Yes it may be less prone to fragmentation but for some reason OS 2 seems to load quicker and have less disk thrashing on FAT16 than on HPFS. At least thats what I've found on my last OS2 install(accidently did an easy install). Still testing though. And FAT16 is read by most other OSs as well.

Merry Christmas.

Mark, your findings about boot-speed and thrashing indicate a memory bottleneck. Since HPFS is an installable file system driver it needs additional memory for the driver itself plus up to 2 MB for cache.
So, due to the increased memory demands of the (additional) HPFS file system, more memory paging to and from disk will happen at boot time in a system with very little memory (below 8 MB)
On a "plain vanilla" installation, the size of the page file \os2\system\swapper.dat is an indication of the overall memory situation: If there is enough memory in the system for the base system and you did not set any special paramters on the hpfs.ifs line in config.sys, swapper.dat will not grow beyond 2 MB.
