Is there any other WBFS tools? It only copies a file correctly about 1/3 times which is very annoying.
What do you mean by it's not copying correctly? Does the program freeze or does the file become corrupt?
Without knowing anything, some people do experience issues transferring files from one external drive directly to another. Their issues typically get solved when they transfer form external drive to PC, then again from PC to destination drive.
There are a couple other programs: WBFS Intelligent GUI is one (I believe), and ncWBFSTool is another.
