# What does the "Tidy large folders & clear caches" step of Run Tuhi do?

It's the Free Up Space engine running as part of Tuhi: it moves folders that your rules already match to your fast drive, leaving links behind so they still open from the same place, and then clears well-known app caches.

It only moves what your rules cover — it doesn't pick new folders on its own — and if your fast drive isn't connected, the moving part has nowhere to go. To see or change which folders your rules match, see the [Moving folders FAQ](https://storagestudio.us/faq/moving-folders/).
