The other day, I was having trouble installing a kernel update because my root partition was getting kind of full, which I thought was odd because most of my big files were on another partition (a DOS partition, actually, shared between Windows and Linux as a place to keep games, pictures, MP3s, et cetera). So I did a little checking and discovered that my home directory was a couple hundred megs, which didn't make sense to me as the total of all the visible files was a lot less than that. Then I started checking the sizes of INvisible files, which led me to the .thumbnails directory, which contained the majority of the offending files. Many of them were thumbnails for images I no longer even had on my hard drive in full form. There were so many of them that 'rm *' failed because the shell couldn't handle that many arguments! Is there anywhere in KDE to set a maximum size for this directory, or a time-based expiration, or something? I found the per-image setting, but I don't want this thing to regenerate to a huge size if my brother decides to sift through porn. Or is this directory being managed by another program?
