Question Keep largest size of copies and move others to a backup folder

[DynV]

There's a folder with some files having different copies of it, ie abc.ext, abc (1).ext, abc (2).ext. Those with different copies are about the same subject but some include more detail than others. In the--vast majority--of cases a larger file yield a better result, so I'd like all other copies to be kept in the small chance it's not the case. After the moving of smaller versions is done, I'd like for the remaining files that were a copy (in the example abc (1).ext and abc (2).ext) to be renamed as the original filename (in the example abc.ext).

Thank you kindly for your assistance

One of those 2.

Please notice the files were renamed in the following example; the content of them is differentiated by their file-size.

1. BEFORE
   \
   o.ext 50 KB, o (1).ext 75 KB, o (2).ext 60 KB, p.ext 180 KB, p (1).ext 150 KB, p (2).ext 300 KB
   \backup\
   [empty]
2. AFTER
   \
   o.ext 75 KB, p.ext 300 KB
   \backup\
   o.ext 50 KB, o (1).ext 60 KB, p.ext 180 KB, p (1).ext 150 KB
