Ya multitool looks nice.

IS will let you virtulize the wtf file:

[Innerspace] ISBoxer Toolkit - Zero to Hero in 30 minutes Setup.

Maybe thats not what you want to do but maybe it can be.

I use this sync program (not for wow) but it makes lots of failures but it does get 90 percent of your files there and when it makes a failure it dosnt hurt if you set it up to write to a temp file first.
