Works fine here, even displays a 2.8GB file which kind of surprised me. FAT32 volume is 31GBs.
Perhaps there is a broken short name? Winos2 does display the 8.3 short names for long names, which is nice as they just don't show up with a JFS or HPFS volume.
Could be the version of the fat32 driver as well, I'm using the latest which may not have been released yet.
I do have the patch that Doug mentioned installed and DOS sees,
O:\>dir q:
The volume label in drive Q is FAT32.
The Volume Serial Number is 1709:2826.
