MS holds several FAT-related patents specific to the storage of long filenames (see ​http://en.swpat.org/wiki/Microsoft_FAT_patents for links). However, none of those should preclude us from reading the Windows LFNs so that they don't show up as blah~1.ext. As we store LFNs differently, we could at least read the Windows LFNs and when saving to a new LFN, then store using our method.

Currently, formatting a FAT32 volume involves running a standalone executable (fat32fmt.exe) with its own syntax.

Formatting FAT32 should be accomplished as with any other filesystem under OS/2, via the format command:

FORMAT X: /FS:FAT32

It should also be possible, then, to enhance PMFORMAT.EXE to support formatting FAT32 (not that such an enhancement belongs to this ticket or this project).

Writing large eas to a VFAT drive causes a system trap. The eas are a thumbnail created by Lucide. It also traps in fat32 when you try to copy a file with large eas attached (again a thumbnail created by Lucide). Steps to reproduce:

1. Place a pdf file without a thumbnail on the VFAT drive.
2. Open it with Lucide set to create thumbnails
3. When you close the file or Lucide (which is when the eas get written) you trap

The same thing occurs on a FAT32 drive if you copy a pdf that already has a thumbnail as part of its eas.

Note this was not happening with r280 but was with r276 and r277.

The following is the trap screen from the VFAT trap described above. I have a system dump of both traps above. I also have a system dump from just repeatedly accessing the drive from the drives folder which was also fixed by turning off eas. All these problems go away with eas turned off.
