A. This depends on if the file is being created on aFAT or NTFS partition. The maximum filename length on a NTFS partition is 256characters, and 11 characters on FAT (8 character name, . , 3 characterextension). NTFS filenames keep their case, whereas FAT filenames have noconcept of case (however the case is ignored when performing a search etcon NTFS). There is the new VFAT which also has 256 character filenames.
