Import texture folder Mac

[okto]

Hi everyone,
could it be possible to import new texture per folder in Mac?
it's kinda waste time to import it one by one and beside my Mac keep getting slower and slower when doing that ( i dont know the problem)
i try to use the ruby script massmaterialimporter.rb and put it in library>app support>SU8>SU>Plugins
but only the folder name that shown in paint bucket tools. not the file.
please tell me what it suppose to do

thanx everyone..
