FAT32 ist an sich auf 2 TB begrenzt, unter W2000 kannst du nur 32 GB FAT32 erstellen.
Theoretisch kannst du also einen 2 TB großen Ordner erstellen, praktisch darf die Anzahl der Namen der Dateien aber nur maximal 64k -2 (65536-2 = 65534 Stück) erreichen.
Ein FAT32-Ordner ist also begrenzt durch 65534 Dateinamen, 2 TB Partitionsgröße und die Plattengröße, was immer zuerst erreicht wird.

According to the Windows Resource Kit however, the maximum number of
file entries is limited to 65,535 for each (sub)directory when using
FAT32
. . .
There are 64k directory blocks per directory. With a strict DOS 8.3 naming
convention, that would mean 64k files. However, long file names require a
minimum of two directory blocks, one for the 8.3 name and an additional one
for the LFN entry. Note however that the number of directory blocks required
by the LFN is based on the size of the LFN. As the length of the file name
increases, so does the number of directory blocks. Hence, with long file
names being used you limit yourself to a max of 32k files or less.
. . .
Any folder or filename over 13 characters will use 3 or more entries.
There is a limit on sub folders of 64K entries. (FAT16 and FAT32)
If you use nothing but 8.3 size file names, then you can get 65,535
(give or take 1) but in practice, the limit is usually reached around
20-30,000 files with an average mixture of long and sort file names.
. . .
The fundamental limit of FAT16/FAT32 file systems for any folder, no
matter what is the free space, is the limit of (65536 minus 2)
files+subfolders with short DOS names -- or approx. 20000
files+subfolders with the long Windows names.
The practical limit for long names may be less -- because of the
fragmentation of directory record after files deletion.
But each nested subfolder can contain the same count (65534) of
files+subfolders in turn -- this limit is the one-level limit.
