The best solution depends on what exactly you mean by “duplication”.

If you need to compare whether the content of directories is the same, then I'd recommend an external tool like WinMerge or SearchMyFiles.

If by “duplication” you mean that the names are in some way similar, then the easiest solution might be around an Excel table, in which you would express the condition of “duplication” with a formula for each folder name that results in a suggestion whether that folder should be deleted. Then you can sort and visually compare those directory names, and override the suggestion as needed.

To be more concrete: For the formula, it often can be useful to apply a regular expression – see https://strugglingtoexcel.com/2013/1...ssions-in-vba/. If, as one might infer from your example, duplications just differ from the original by an appended space and number, then you can easily get the original name with the formula 
=RegExpReplace(RC[-1]," \d*$", "")
. In the next column, you can then search with MATCH() whether that name exists in any previous row, and if so, write something like “move” in the cell. Then you can have your macro read that value and handle each row accordingly.
