Extracting .gar files?

[land0n12343]

I have a .gar file, It works with a modified version of N3DSCmbViewer but one of the folders in the .gar is called "C:" which causes the program to flip out and not allow me to mass extract the files and folders, any other way to open .gar and extract contents in few clicks instead of right clicking on every file in N3DSCmbViewer?

I tried another too called GAR-ZAR unpacker but it doesn't work... I wish I could just rename the folder in the .gar
