[Enhancement] Filename length during saving on disk

Bug Description

Hello. From time to time, when I have to save my books from Calibre to disk, the program writes me that the files are too big. As I can understand, it is because the filenames of the books are very long. I have thousands of ebooks and other documents in Calibre, and many of it has a very long filenames. So manually renaming the filenames is very uncomfortable.
Can you make that the program will rename the filenames itself automatically to maximally possible filename length, please?
Thank you.

P.S. Sorry for my bad English.

On what operating system is this. On windows calibre automatically
restricts file name lengths already when saving to disk.

On linux filesystem limits are 4096 characters. You sayig your filenames
are longer than that? Or are yu saving to some non-native filesystems
like a FAT32 filesystem?
