This is how I have my yableroot set up.

YABLEROOT = “C:\3D\YafRay\yablex\ emp”

#File System Operations

#RENAME

YABLEROOT = "C:\\3D\\YafRay\\yablex\	emp"

"""
#Examples:

#YABLEROOT = "C:\\Documents\\YFexport"
#YABLEROOT"/home/username/YFexport"

"""
VIEWERAPP = "c:\windows\explorer"
#CRAFTERFILE = "C:\crafter\data\preview.mat"
