I'm in desperate need to free up some disk space on my Macbook, so I went on Steam to delete a few of the heaviest games I haven't been playing.
Then I noticed something puzzling.
I had ~15GB free on my SSD when I went into my library and deleted CS:GO. According to Steam itself, CS:GO was roughly 8GB. I deleted it, by choosing "Delete Local Files". Having just deleted it, I checked and I now I have ~18GB free!
Steam told me CS:GO was using 8GB, but I only recovered about 3GB by deleting it.
How is this possible? Did I do something wrong? Are there "hidden files" or something similar that I can manually delete to free the remaining 5GB? Is it because CS:GO is a Source Engine game?
Before deleting CS:GO, I also deleted Borderlands 2 via the same method, and although I failed to specifically check how many free GBs I had before and after deletion, I'm confident that the same thing happened. I'm pretty sure I didn't get back the ~7GB it was using.
In essence, I'm worried that Steam is not freeing up space adequately when I delete my games. I'm thinking of deleting Steam as a whole, since I haven't been gaming all that much recently anyway. I wonder if that would fix this problem.
