This is what I'm using in a quick action: G:\Converted\$ifgreater(%_bitrate%,1400,$ifgreater(%_birate%,5000,%_bitrate%,'-=24.bit=-'),)\$upper(%_extension%)\%artist%\%_directory%
But it only moves music files within original folder not music files in subfolders?
%_directory% always refers to the current folder.
If you have files in subfolders (?) then this is the current folder.
You could rename the _DIRECTORY with an absolute path in which you $replace() a part of it with the new data and keep the rest.
More details may follow with actual examples of the current path and the desired path.
