Logical File Structure
- 32 bits allows for a theoretical 4 GB file (assuming byte addressed files). Notice on xi, however, that the “df” command displays some file systems that “break” the 32-bit barrier :)
- As discussed earlier, files also have metadata (name, type, size, owner, group(s), permissions, timestamps, disk & data block pointers, etc.).
- UNIX: stat() and fstat() return metadata; ls command displays them.
