how can I delete kcore?

I have a huge file taking up over 600MB of space called kcore, a core dump from a failure of KDE, I think. I have tried rm -f, but it is denied. I booted into failsafe, logged in as root, tried it again, tried to chmod +w, and it said it changed, but when I looked at it again, it was still readonly. I cannot delete it! I dragged it to the trash, but it still didn't go away. I need that disk space. I don't want to reinstall SuSE 9.0. I just got it working on my laptop just right. What is the problem? --Bill

is it in /dev? if so, do NOT delete it! kcore stands for KernelCORE, not KDE.

I thought it was a very bad big thing I didn't need. So, the kernel core is over 600MB? I thought it was a relatively small thing, like the ntoskernel in XP. Well, I have over 800MB free now, so thanks again! Glad I did not succeed in deleting it. I had just run out of room trying to do a backup without enough space for it. Guess all I need to back up are my fstab, /etc/pcmcia and /etc/sysconfig to get back my work in case of a crash. Did I mention thanks!? --Bill

Hi, I have kcore under file:/proc and it's 519MB.
How can I delete it?

kcore is located in /proc/kcore and is NOT a real file generally. Try du -sh /proc/kcore and you will see that it is not real (0 bytes), but a virtual file that maps directly to your physical memeory. You can copy it and read from it as though it were a real file, however. It ussually does not take up real space.
