File Naming
- Virtually all modern OSes use a hierarchical file naming system.
- Note that the separator character distinguishing path components is different (/ = UNIX, \ = DOS/Win, : = Macintosh).
- Different limits exist as to what are legal file names and how long they can be:
- DOS FAT filesystem: case insensitive “8+3”/component.
- Win95 FAT: Kludge of the first order; up to 255 chars.
- WinNT NTFS: case insensitive; up to 255 chars.
- UNIX: case sensitive; from 14 (old limit) to 255 chars/component.
- Macintosh: case insensitive (even though stored sensitively); up to 31 chars/component.
