Understood and agreed.
There are clean-up routines that are already in place and this is an addendum. This server is strictly internal so we do not encounter issues related to hosting, e-mail, spam, FTP, etc. However, we do run a plethora of programs and special applications. Unfortunately, in busy times dictated by "just get it done", not every process is written, ran, or tested to par.
Most of the clean up is handled by other routines so if the box does reach the eightieth percentile it's at the point where humans must intervene because (1) there's old junk hanging around that cannot be dumped automatically (or isn't being found by the cleaner-uppers), or (2) our work has actually ballooned to the point where we truly need more space. Ergo, this program is aimed at aiding in that decision: remove, archive, and/or expand?
