Not really sure that it's heavy on the CPU usage. I haven't noticed if it is, but my system is pretty good for warcraft.

I've not used any sounds with IS Boxer, sorry.

There isn't really an advantage to multiple folders from a performance point of view. Multiple folders, with symbolic links, gets you different configuration options. However, you can do file virtualization with IS Boxer.

It is really easy. In the top pane, expand virtual files and then click on Config.WTF. Then in the top pane, expand characters and drag them down to the bottom left frame. I virtualize my files as, "Config-ToonName-ServerName.WTF".

If you'd prefer to use your F drive, instead of your C drive, you can change the path. Right click the Inner Space crosshairs, on the task bar. Select Configuration. Go to the Game Configuration tab. Select World of Warcraft from the drop down menu. Then select default profile, from the drop down menu again. Edit the "main executable path" to the F drive folder.
