To be able to load faster, Origin stores data in so called cache files. Origin checks on startup if those files are available and if so, they are loaded. If they are not available, they are created.
Over time these files accumulate out-of-date data and because of this, it’s best to delete them from time to time (just as you delete your browsers cache from time to time)
Which files are those ?
Make sure Origin is not running anymore by clicking on the Origin menu in the system tray and choosing Exit.
The files to delete can be found here:
- C:\ProgramData\Origin — Everything except for the following sub directory: DO NOT DELETE: C:\ProgramData\Origin\LocalContent
- Origin folder in C:\Users\<username>\AppData\Local\
- Origin folder in C:\Users\ <username> \AppData\Roaming\
Deleting these folders has no influence on the games in your Origin library. Those are saved to your account and have nothing to do with the actual Origin client.
The Diagnostics Tool for Mac does the same and more.
