after a long research, I finally found out that pathnames cannot be longer than 256 characters even in the latest Microsoft Windows 7. I really don't get it why there is such a stupid limitation, since NTFS can handle up to ~32,000 characters path length without any problem since more than a dozen years! Isn't there any possibility to change that? Or are there any practical solutions to avoid that?
260 characters are just very few for even simple use cases like some nested photo directories with long file names.
