Just a thought here, but did you happen to fall for the "Sulfnbk.exe Virus Hoax" in the past? Do you have the "Sulfnbk.exe" file on your computer? Read the links below:
Description of Sulfnbk.exe and How to Replace the Program File
If it's there, then maybe the instructions at the links below will help you restore the long file names:
190418 - No Long File Names on the Start Menu After Windows 98 ...
I am running Windows 95 and using long file names, but they sometimes seem to get lost or deleted somehow
Hope this helps.
I posted this on the Win95 forum, but got no hits.
3 Gig SCSI
When I look at either a CD-Rom or floppy with this computer, I see only truncated file names in the DOS 8X3 format. Every other computer sees the long file names from the ROM or floppy.
The computer shows long file names as usual otherwise. If I copy or move a file from either the CD or floppy, it is stored on the computer in the 8X3 format.
Need some help here please---
