is it true that the FAT32 only supports these file timestamps?

  • Creation time (birth time)

  • Modified time

  • Change time

  • Access time does not exist on FAT32.

With exFAT all 4 timestamps are supported:

  • Creation time (birth time)
  • Modified time
  • Change time
  • Access time

It would be good to know how the behavior is on current Windows 10 (20H2) and it has been tested in real.

Yes, if the file system is FAT32, the entry of last access time cannot be written, or be changed.

The specifications of the exFAT file system include:

Timestamp granularity of 10 ms for Create and Modified times (down from 2 s of FAT, but not as fine as NTFS's 100 ns)

Timestamp granularity for Last Access time to double seconds (FAT had date only).

Timestamps come with a time zone marker in offset relative to UTC (starting with Vista SP2)

  • Thanks for the answer. Do you also know about change time, so in NTFS is change time -> MFT Entry modified. Is it also supported in FAT32 and exFAT or is there not? Other question do you know if there is file manager (GUI) on Windows 10 (20H2) where I can see all 4 timestamps regardless if the file system stores the timestamps or not? Jan 21, 2021 at 13:06
