"*MLDonkey* is currently not able to compute MD4 hashes for
those files on the windows platform past the 2GB mark
so those files will never finish. You should read this thread:
http://article.gmane.org/gmane.network.mldonkey.user/3028
The people in this thread discussed and produced the
original patch that enabled MLDonkey corectly using files
> 2GB on Linux platforms but it was always clear that it was
no use for Windows."

Maybe this can help:

http://gnuwin32.sourceforge.net/packages/libgw32c.htm
If you want to use large file support (i.e. to replace the standard 32 bits
msvcrt functions by 64 bits),
add the defines -D_LARGEFILE_SOURCE=1 -D_LARGEFILE64_SOURCE=1
-D_FILE_OFFSET_BITS=64

http://gnuwin32.sourceforge.net/install.html
Large-file support

Packages newer than 1 April 2003, have been compiled with large-file support
(LFS). These programs should be able to access files larger than 2 GB, up to 9
EB (exabyte) = 9,000,000 TB (terabyte) = 9,000,000,000 GB. If you never use
files larger than 2 GB, there is no need to upgrade packages just because
large-file support has been added. Note that the current MS-Windows
implementation of file systems allow for maximum file sizes of 4 GB on FAT16,
128 GB on FAT32 and 16 TB = 16,000 GB on NTFS (there may be smaller maximum
sizes for MS-Windows versions earlier than XP).
