Many users of Windows 9x were asking if there is a possibility how to run windows on different file system as FAT16 or FAT32. Well there is one possibility.

ifshlp.sys

this file is "Installable file system" helper.it recognizes which filesystem is installed and loads proper drivers for it...

the questions are?
1. Can it be upgraded?
2. which filesystems it can handle after upgrade?

there are drivers for NTFS in win9x, althought they need to be corrected, and there is possibility to use other filesystems if there should be a driver...

I am not capable to program new drivers of ifs helper ... but i am sure there is somebody.
