I’m out of disk space, so I wanted to move the package cache to a location on another hard drive, however when trying to follow the official documentation (Unity - Manual: Customize the Asset Store cache location) I noticed that the Package Manager page is missing in preferences.
Any help would be much appreciated
Any errors in the Console?
What happens when you click on the gear in Package Manager that normally opens the settings?
Restart Unity? Which version?
What is Dreamteck? Maybe that somehow interferes with the remaining preferences.
Hi @lordubbe ,
Just to make sure, what Unity Editor version are you using? This UI should be visible in Unity 2022.1 and newer versions. You will not find it in 2021.3 LTS or older.
That could indeed be the issue. I’m using 2021.3 LTS 
Any way to do this in these old versions?
Absolutely, but it’s a more “manual” process. You can follow the steps described in the 2021.3 manual under the Using a configuration file header to move the UPM global cache elsewhere. The UI is new with 2022.1, but the underlying mechanism was added before and backported to the 2019.4 LTS, 2020.3 LTS and 2021.3 LTS.
Note: unfortunately, you cannot change the Asset Store package download cache location this way on 2021.3, that is only a 2022.1+ feature.
