Review for Folderpane Tools by Sandel-ua
Rated 5 out of 5 stars
Greate tool!!! Thanks...
But one think..
Highlight this with RED color --> "This extension must be configured before use. To open the options window, open the Tools menu, select Extensions, and double-click on the extension."
I spent about 1 hour before figured why it didn't worked
