It would help if you tell us which os you are using.

In general, the proc directory is a make-believe file system.

First that means that it is a seperate file system. If / and /usr are filesystems and / is tight on space, freeing up space in /usr does not help /. Ditto which /proc and /.

But /usr is at least a real filesystem. If you free up space in /usr, well then you have some space in /usr where you could put some files. That is not true of /proc. /proc is not real disk space and you cannot put files there.

/proc is a representation of the processes that are running. Yes, you can tune a kernel and limit the number of proceeses that can run. That will make /proc smaller.

Before you do that, look at /proc immediately after a boot. It will be much smaller. But you won't have any more disk space.
