Is it safe to delete Arc cache?
Web pages, images and scripts that Arc saved so websites load faster.
Safe
Its owner recreates it by itself when it needs it, and nothing you made is lost.
~/
What it is
Arc is built on Chromium, which keeps its web cache in the Caches folder under the same name as the browser's data folder in Application Support. Arc downloads anything it needs again, so your spaces, pinned tabs, passwords and history aren't affected.
If it's removed
Websites load more slowly the first time you visit them again, while the browser downloads their content again. You stay signed in to websites, and your bookmarks, history and passwords aren't affected.
How it's removed
Moved to the Trash, where you can restore it. Quit Arc first.
The free analyzer finds it and explains it. Removing it is Pro, after a review sheet that lists every move and command. It starts checked in the Cleanup checklist, except inside Documents or Desktop.
