WTF Folder Problem

I have been having big trouble with my game crashing over time for the last few days. I narrowed it down to my WTF folder. I multibox with my 5 shammans, things are going smooth, and after 30min-1hr the game slowly slows down in fps and slows my computer down until the game crashes. Then i go and delete my wtf folder and its as good as new for a good 30 min lol. Is there a way to run the shammans on different wtf folders? or maybe on different Warcraft installs completely? If not does anyone know of this problem or a solution?

Edit: It is not my storage space i currently have 938g of free space.

I run all kinds of groups (5x same chars and several mixed) from the same WTF folder most with alot of addons activated and never ran into the issue you described.

After deleting your WTF folder do you restore any files/directories/addons or bring up the clients with the folder basically empty?

Did you try a chkdsk on the partition that folder resides on?

After i delete the WTF only thing i do is log into each character so the suite can see the characters and i only have 1 addon when is jamba or whatever, and the partition is primary on my main hd that it is on.

Look in the WTF directory (and sub-directories) and see if there is a file that is recently updated. Also look for really huge files.

The crash report from the game would probably help, if you cant figure this out
