# Will clearing caches with Storage Studio make my Mac faster?

Not directly. Clearing caches frees disk space, which helps if your startup disk was nearly full — then macOS has room for virtual memory and updates again. But caches exist to make apps faster, so right after clearing, an app's first launch can be a little slower while it rebuilds what it needs.

Storage Studio only clears regenerable cache data that apps recreate automatically — never your documents or settings.

If your Mac is slow and the disk has plenty of space, look at memory or busy apps instead — [ask Tuhi](https://storagestudio.us/faq/performance-battery/can-tuhi-tell-me-why-my-mac-is-slow). More in [Freeing space](https://storagestudio.us/faq/freeing-space/).
