Do you need a lot of disk space for those target files?
5-6 Rust projects just filled up my 16GB thing.
Well, someone suggested me to use a specify target path if I am focused on one project. (Because target files of different projects override each other.)
But I did not do this because I am a Rust noob who do not really "focus" on just one project.
Btw, I dual boots Mac and Linux. So the amount of target files double.
