Ok, I have something puzzling me. My /home partition on Slack 10 is about 30gig and when I ran "df" last night it was about 72% full. I haven't downloaded anything, but my /home partition suddenly appeared as full whilst I was logged in. My system became sluggish and applications froze because of lack of disk space, and running "df" confirmed this. The funny thing is that when I did a reboot, it showed that it was 72% full again. Slack stores temporary files for all users in /tmp so I know that it wasn't filled with temporary files. My adsl modem/router has not shown any web activity apart from when I browsed a few sites, so I doubt if my system was cracked into, but could this still be a possibility or could there be another explanation? I am completely baffled coz it's never happened before on any of my Linux systems.

Are you accessing picture files when you are on your system? It could be thumbnails.

Nope, I am not, thats the strange thing. I didn't download anything, checkout but the disk suddenly went from having a few gigs free to being full. It's really puzzling me coz like I said once I restarted the system all was okay. I wonder if there is an app misbehaving somewhere.
