Bug [SOLVED] Unity using all disk space whenever I open a project

So I recently installed a new version of Unity (2022.1, not beta or alpha) and I installed the UWP and WebGL and I ported two 2D projects to the new version from 2020.3 LTS, and it said that I needed to import a newer version of URP, so I did. After I did that, it said I had less than 1 GB of disk space, and sure enough, I had 400 MB.

I tested this for a new project using the 2D URP template and it did the same exact thing. How could I reach a resolution? This has never happened to me in the past!

 

How big are your drives and how big are the projects in question?

Unity projects get rather big; you need some reasonably sized drives to accommodate.

 

There's a handy utility called TreeSize (free version) which maps all the space used on your drives. If you have a small drive it should help you free some space. My main system drive is only 500gb so used it a lot to clean up space but I try to keep this drive just for programs rather than projects.

My projects are kept on another drive because they get quite big. Library folders take up the most (why can't PackageCache be centralised rather than copying for every project???) So, I've used TreeSize to delete a load of Library folders for projects I haven't accessed in a long time. When I say big, I mean up to 9gb for a small project, per project. So bear that in mind too!

 

My drives are quite small but I have a 128 GB drive and the project, two are literally just a 2D template and one when built is less than 30 MB so I assuming somewhere around 500 MB in the editor. I do not know exactly though

 

Dont think you should delete out of appdata but its your call what you delete if you are sure its temp. Temp files usually in temp folder

 

I just went from 4 GB of space to 7.12 GB, thank you so much! TreeSize definitely helped me. I haven't tested Unity but I will soon

 

How big is your drive? Maybe uninstall games or software no longer in use. Its important you have a sizeable amount of free space on disks otherwise its rewriting a small area many times / wearing down disk life.

 

I can finally use Unity! Thank you so much! I have a 128 GB hard drive but I want to upgrade it soon.
