# exFAT

8 Hacker News commenters recommended exFAT and 7 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months.

**Verdict:** Recommended as the most portable file system, with native read and write support on Windows, Mac and Linux. Critics agree it lacks journaling, so it can corrupt data after a crash.

## Why people recommend it

## What people warn about

- No journaling, risks data corruption (5 comments): "exFAT has the lovely feature of potentially not only corrupting the file, but also corrupting the metadata for the surrounding system as well."
