[PROBLEM] Running out of disk space

[Darkguy]

Thanks - but that search only yielded the two video files that were being downloaded last night.

BUT: right now, all of a sudden, df -h only shows 1.7 GB of 7.4 GB being occupied (which sounds about right); is it possible there is some sort of script/cron job running every 24 hours that looks into reported disk space vs. actual disk space and frees up the discrepance (like some sort of TRIM)?

If so, is this some command I could also run manually if need be?
