Rider takes too much disk space
There are some special folders which are used by Rider to store its data (logs, caches, old snapshots, etc.) Typically, the size of those folders should not be significant. However, in some cases, size can increase noticeably. In these cases, you might want to delete obsolete files and folders.
If you’ve noticed that Rider occupies too much disk space, you can safely delete the following folders:
Rider2019.3.x or earlier versions

Contains installer log files. - %LOCALAPPDATA%\JetBrains\Shared\vAny\Sessions

Are those files the reason Rider complains about low disk space?
The notification surprised me, because there are 30+ GB available. Do you know more?
