FAT32 is fully supported and used as boot drive. Depending on the BIOS used, up to four LBA hard disks up to 128 GB, or 2 TB, in size are supported. There has been little testing with large disks, and some BIOSes support LBA but produce errors on disks larger than 32 GB; a driver such as OnTrack or EZ-Drive resolves this problem. FreeDOS can also be used with a driver called DOSLFN, which supports long file names (see VFAT), but most old programs before Win95 do not support LFNs even with driver loaded unless they have been recompiled. There is no planned support for NTFS or ext2 or exFAT, but there are several external third-party drivers available for that purpose. To access ext2fs, LTOOLS (counterpart to MTOOLS) can sometimes be used to copy data to and from ext2fs drives. NTFS support is partially provided by software such as NTFSDOS and NTFS4DOS.
