Why is unity taking up so much space?

    Unity takes 39gb on my ssd. I have 7 subfolders in the hub folder. 2020.3.42f1, 2021.3.9f1, 2021.3.10f1, 2021.3.14f1, 2022.1.23f1, 2022.2.0b16 and 2023.1.0a19. It seems to be these subfolders that takes up so much space. Why?

    Because you have 7 versions of Unity installed.

    It's pretty common to have a number of versions installed. I must have a few dozen by now.

    Each version is its own separate installation of Unity. An installation is around 5.5GB and you have seven of them therefore it's using about 39GB. That's not the only thing that will quickly eat up disk space. Assets downloaded from the store to be imported are also kept on the main drive.

    Can i delete some of them? I haven't updated unity for some time, so it must have happened the last time i updated unity.

    Go ahead. You can uninstall versions from the hub by clicking the gear icon on the appropriate version under the Installs section.

    One thing worth mentioning, if you installed a unity version, the .exe for the install itself will stick around (even though it's useless now, you already finished installing) - it takes a good amount of space. It's almost like another duplicate unity install. I always try to remember to delete it when I need some space.

    Is it best to install a version that has long term support (lts)?

    I went with version 2021.3.14f1, since that was the recommended version. I have uninstalled the rest. Unity only takes up about 14gb now.
