Thanks skwire i've download it now. Is this the latest version ?
I've test it and i saw the icon change in only the last directory under the root dir.
I'm wondering if your program can change the icon if there is no file (but the desktop.ini) in a sub-directory but only an another directory and so.
In fact i would like that the folder containing only a subdirectory and no individual files counted as empty.
It's seem akward at a first glance, but if we issue a "shift" "*" under a root dir it will expand all of the subdirectories and then we will be able to easily visualize wich subdirectories that contain at least a file and witch are empty
