So here is the problem: I'm using Ubuntu 20.04 on WSL2 on Windows 10, and I noticed that after removing files on Ubuntu I was not getting the space back that was taken up by the removed files. For example: Before I deleted files on Ubuntu it showed on Windows explorer that my free space on the (C:) drive was around 46GB. Then after I deleted around 10GB of files, which in my case where some temporary Gatsby sites, it resulted in even less free space, around 45GB. Which I thought was very weird.
So I guess my question is: How can I get back those unused bits? Is there some terminal command which I can use or can I do something via the windows gui or something.
PS My previous question got closed for a lack of detail. I hope this time around it will suffice. Also please do not downvote this without some comment on why, but at least give me some information as to why.
