Caches
This folder stores temporary cache data used by Microsoft OneDrive on macOS to speed up syncing, sign-in, and local file access.
What is Caches?
This item is the cache folder used by Microsoft OneDrive inside its macOS app container. OneDrive is a cloud storage and file sync service that helps you keep files available across your Mac, the web, and other devices. The data here is created to improve performance during everyday use, such as syncing changes, loading account information, handling Finder integration, and working with Files On-Demand. Cache folders usually hold temporary files that the app can rebuild when needed. Users most often encounter this data when reviewing storage usage, troubleshooting sync behavior, or cleaning up app data on a Mac.

Safety overview
Status: Mostly safe
This is cache data for OneDrive, not your main synced documents folder. Removing it is usually low risk, but it can force OneDrive to re-download temporary data, rebuild local cache files, or take extra time to resync. If OneDrive is running, deleting cache contents may interrupt current syncing or cause temporary sync issues until the app recreates what it needs.
Recommendation: You can remove this folder if you need to recover space or are troubleshooting OneDrive on your Mac. Quit OneDrive first, then reopen it afterward so the app can rebuild its cache. Keep it if OneDrive is working normally and the space used is not a problem.
