Nope.  There is a limit on the size of a FAT partition of 2GB.  FAT32 wasa
created as a replacement partly for that reason.

[whooper at butters whooper]$ sudo /sbin/parted /dev/hda print
Disk geometry for /dev/hda: 0.000-19077.187 megabytes
Disk label type: msdos
Minor    Start       End     Type      Filesystem  Flags
1          0.031   9452.307  primary   fat32       boot, lba

Information: Don't forget to update /etc/fstab, if necessary.

[whooper at butters whooper]$ df -h

[whooper at butters whooper]$

Now there is a limitation for a single file under some OSes of 2GB on
FAT32 partitions.  Maybe that is what is confusing you?
