Deleting big files is really slow

Hi. I'm new to Fedora Core 6, and I'm also quite new to the Linux world in general. So please explain things to me as you would explain them to a child

I've tried erasing a big file (FC6's own DVD ISO) I have on a VFAT partition, and it is really really slow. It says "starting process" but then it stays on 0% forever while the HDD is doing some hard work. After a couple of minutes I decided to cancel it. I then opened a konsole, used rm -r to delete it and it deletes it on half a second :\ What's the problem?

Oh, I'm using 2.6.19-1.2895.fc6 and KDE 3.5. The partition is mounted in fstab as:

/dev/hdd1 /media/hdd1 vfat user,rw,exec,auto 0 0


PS: How the hell do I disable spell checking on Konqueror? It's driving me crazy!

vfat isn't really optimized to handle large files. In fact, I'm a bit surprised you can put a DVD iso on vfat, I thought there was a 4GB filesize limit...

Anyway, typically, large files like DVD's should be stored on xfs, jfs, or other filesystems that handle large files better.

If done from the GUI, was probably copying it to the trashcan - twice the I/O.
The "rm" just does the job, but isn't recoverable.

Oh, on Fedora there's one trash can for the whole system, not one for each drive like on Windows? Interesting. Anyway, that has to be it then. Thanks a lot.

The ISO is 3.3GB by the way so it fits on a vfat partition.

Anyway I'm thinking of formatting a 250gb drive with 2 partitions. I want it to be easily accesible from a Windows PC (on a network), but then I would have to use vfat, isn't that right? And I will effectively put big files in there. Anyway I don't think I'll ever exceed the 4gb barrier.

Still researching the post-scriptum though :\


delete, file, vfat
