Defragging While GW Is Running

Hey guys, I'm running a disc defragment and all of a sudden I experienced extreme lag which I deduced was caused by the defrag tool moving the GW.dat. I was wondering if playing the game while the file is being defragged could cause future problems.

Thank you in advance.

Defragging your computer takes up alot of disk space. So basically you WILL experience graphical lag while playing games while defragging.

Defragging is designed to be done when no other programs are running--you do know what defragging actually is, don't you?

Defragging while playing = BAD

btw, it won't work if the file is being accessed.

Right. Guild Wars does NOT defrag with a basic disc defragmenter, HOWEVER, you should never EVER have anything up and running while defragmenting. It takes priority over everything else, so you will lag, and it also moves system files and compresses other files. So that's why you're lagging like hell just defragging.

Try DiskKeeper 10. Not only is it capable of defragging the GW.dat file, it has intelligence that will keep it from launching if your disk is performing I/O functions, so you won't experience lag.

If you're defragging in the background with a the basic defrag tool with Windows, you are asking for trouble, as others have intimated.

I would set your computer to defrag when it wont be interrupted, like when you sleep. Probably should kill the internet and most automated processes as well.

Someone mentioned in a different thread a very small and useful utility:

You can ask it to defrag Gw.dat (open a command prompt in the "Guild Wars" folder and then type "contig -v gw.dat") and when this is done, launch the game and defrag the rest of your disk!

Wouldn't it be just as easy to close your game, start defrag, go fix a snack, come back and defrag is done then its game on!
I never have anything running when i defrag.
