I have no idea, because I don't use/need such large files.

From within a NTVDM in WinXP a DOS application can access a NTFS file which is larger than 2/4 GB.

Following should also be supported by FreeDOS
(copied out of my source code, not sure where I found it):

FAT+

FAT plus is a new standard defined by Enhanced Dr-DOS and Free-DOS
developers. It extends the capacity of FAT16 (not very useful) and FAT32
partitions (very useful, called then FAT32+ and supporting files up to 256
GB).

For files larger than 4 GB, in Enhanced DR-DOS 7.01.08 WIP the file pointer
can be set with the following new 64-bit DOS function, shown as a modified
excerpt of Ralf Brown's Interrupt List:
--------O-217142-------------------------------
INT 21 - Enhanced DR-DOS 7.01.08+ - "Long LSEEK" -
SET CURRENT 64-bit FILE POSITION
AX = 7142h
CL = origin of move
00h start of file
01h current file position
02h end of file
BX = file handle
DS:DX = pointer to (signed) 64-bit offset from
origin of new position
Return: CF clear if successful
DS:DX unchanged, new 64-bit position from
start of file written into memory at -> DS:DX
CF set on error
AX = error code (01h,06h) (see #01680 at AH=59h/BX=0000h)

Sounds like the Club Dr-DOS Wiki page about FAT+. However I don't know any FreeDOS developer helped Udo in developing the specification and interface. At least FAT+ is not supported by FreeDOS: neither the Kernel nor FreeCOM knows about/uses it. And I think DJGPP does not support it either.

Well, I went ahead and built it myself using both DJGPP 2.04 and OpenWatcom 1.7a:

http://rugxulo.googlepages.com/zip30dj.zip (with Bzip2 support, e.g. "-Z bzip2")

http://rugxulo.googlepages.com/zip30wat.zip (all PMODE/W, all Win32, and zip16 "low mem")

P.S. Things like ZIPSPLIT compile correctly in 16-bit but don't work (and never did, IIRC), just FYI.

	> http://rugxulo.googlepages.com/zip30dj.zip (with Bzip2 support, e.g. > "-Z bzip2") It works! Compression advantage seems to be with larger files. Results with small text files were bigger than without bzip2. With all files tested so far, deflate results are exactly the same as with older Zip versions.

BUT, it seems that "zip -f" or "zip -u" (my DOS builds only) don't work correctly under DR-DOS. However, FreeDOS or Win XP etc. work fine, no idea why (yet ... to the Batmobile!).

CWSDPMI and JEMMEX, but I don't think that's the problem since the OpenWatcom + PMODE/W DOS compiles also have the same issue, even on clean boot. They must've changed something since 2.32, which always worked fine. Very strange. (However, OpenWatcom Win32 of ZIP 3.0 + HX works fine although encodes ASCII-fied Unicode names, ugh.)
