Hi. Excellent work and idea here, thank youjuh9870. I just molded your code and now it has Drag&Drop capabilities and the ability to go back to previous folder with middle mouse action in directory icon or forward to show child folders. It means that you can go from c:\ to any child folder with left mouse action and return to its parents directories all the way back to c:\ or even to "My Computer" again. You can still use right mouse action to open folder in explorer window or left mouse action to execute a file or program. Now it also shows thumbnail pictures tiles for image files and not its program icon. there is no need now for the user to specifies a path in variables.inc
A little problem though, there is a bug especially when changing disks when you go back to "My Computer" root directory and pick other disk, but once you go back to %USERPROFILE%, it then behaves normally. It started to happen when I integrated back and forward functionality and only few times when you go all the way back to "My Computer" or going to windows directory. It doesn't happen all the time, just once on a while. At one point or another it will either not show all items in the folder, show too many, or create incrementally more icons than needed.
It might be the follow path approach or something from the Lua scripts, I'm not sure.

You need to install ImageMagic https://imagemagick.org/

It is a merge of two great folder explorer skins developed by
juh9870 "EXpandable" https://github.com/juh9870/EXpandableFolder and Qwopjoans "RainExplorer" https://www.deviantart.com/qwopjoans

I managed to have them work together.

You will find at first a folder that you can expand its content with a mouse over action and execute a file with left mouse action. You can also navigate back and forward with a middle mouse action.

You'll see a small click box located in the upper left corner of the skin with whom you can show or hide a file explorer by clicking it with. The expandable folder will show the folder name of your last navigation in the file explorer once you hide it.

It has the following capabilities that aren't available in original skins :
-Drag&Drop functionality
-Thumbnail pictures and not just the icon file associated in both expandable folder and file explorer
-EXpandable folder navigation with middle mouse actions
-And much more!

I hope you enjoy it!
