Use the 7Dlauncher and hit the [tool tab]
Click open game folder>then open the Data folder> then right click on the world folder.
Then scroll down to [send to] then [desk top (create shortcut)].
*This will send the world folder (as a short cut icon) to your desk top* Drag it next to your 7d2d icon.
Then go through the steps again, with the 7Dlauncher and do the same for your [save] folder and make that a shortcut as well.
This way you'll have an easy way to open the folders directly to remove the different world maps and your saves for those world.
