The process file system (PROCFS) resides in memory and contains a list of active processes, by process number, in the /proc directory. Information in the /proc directory is used by commands such as ps. Debuggers and other development tools can also access the address space of the processes by using file system calls.
Do not delete files in the /proc directory. The deletion of processes from the /proc directory does not kill them. /proc files do not use disk space, so there is no reason to delete files from this directory.
The /proc directory does not require administration.
