packages take up 10GB, and runtime cache > 5GB... there is no way to do so...
pls either give us control or change it to installation location...

PLEASE sort this out - I have to fight dozens of apps who all lazily insist on polluting my C drive, which is a space limited SDD that windows also insists of polluting with files I can't delete. App developers should never assume a particular location is a free for all.

Please.We need this.My c drive only left 5 GB volume.

https://docs.unity3d.com/Manual/upm-cache.html

The current Linux location is "$HOME/.config/unity3d/cache".

Instead it should be "${XDG_CACHE_DIR}/unity3d/", and fallback to "${HOME}/.cache/unity3d/"

Would be nice to also have an option to use Cache Server/Accelerator for the package cache! We waste a lot of disk space on each single machine that is used for our Unity projects.

Please either give us control or stop abusing our local storage as for install packages they should be downloaded from your server "on demand" every time.

Same here, C is a small SSD drive, full of Unity packages...
I know several people having the same issues, can you please just add a setting for this? (any workaround like a registry key or a config in Unity Hub, or even each Unity version, would do!)

Please add this soon OR at least supply a workaround. We're willing to configure some files in Unity if need be, but having several tens of gigs of drive taken on the Windows partition when you have many heavy assets is very problematic.

Please fix this issue asap. My c: is full of that package crap.

My C drive is setup as a Windows partition with limited space and I'm always forced to cleanup unity files. I can't download my Unity Snaps asset that I bought because of this issue.
