Dear Ben,
this is correct, but I agree it's really bad described.
I will do a feature request for using an array of pathes
without concatination by strjoin.
I have this tested on unix and I hope I have transformed this right
for windows.
path=get_dir_tree('c:\',level=10)
path='c:\'+path
path=strjoin(path,';') ; it's : on unix
print,file_which(path,'copyToClipboard.exe')
c:\gs\copyToClipboard.exe

hope this helps.
