Yes, NTFS (not windows per se, this only works on NTFS partitions) can
handle filepaths up to 32k. But: the shell can't! So every program using
the shell (file open/save dialogs for example) won't be able to handle
such paths at all. So that bigger limit is basically useless.
The only workaround (if you accidentally create such a long path with a
program not using shell API's) is to SUBST a subfolder to a drive
letter. Then you can handle the shortened path from that drive letter on
with the shell again.
