What a sweet little app- and free! Yes, I found the interface a little unusual: I couldn't figure out how to get a new window then saw you just drag a new folder over. And I wanted to remove the word 'alias' from the end of a huge number of aliases, and it worked very well when I told it that 'alias' is an extension.
But so what? saved me a bunch of work and obviously a labor of love. I appreciate the work. And the price :-)
I'd like to give it a 5, but I know the developer agrees there's more work, and that is the only reason I gave it less than 5.
Did I mention it's free?
