Not only on that.

FAT is limited to 8.3 names. On commandline you have to handle them - on WPS it
costs some extra access.

I gave up any use of FAT about 10 yraes ago because it is so bad in compare to
HPFS.
I gavbe up to use HPFS for JFS about 6 yerars ago because HPFS has limits you
would never seen on JFS.

The chance to loose data is on FAT significantly higher than on HPFS.

I can boot more quickly from my eCS CD to get access to anything on the disk
when there is a need for.

You can boot DFSee frm DOS diskette when anything else will not help. But boot
to native DOS to do something with an OS/2 system is rubbish.

The swap file has to be on the most used partiton on the least used physical
drive to get best performance. On an WARP4 system this would be always an HPFS
partiton, on MCP or eCS this will be either JFS or HPFS but never FAT.

There are so many good OS/2 programs around that there is since 10 years really
no need to use a DOS program to do real work.

I use MDOS only to run the old DOS games I own.
