Most of the time while we backup data from our computer to another computer/laptop, sometimes we forget which files/folders we have copied and bymistake we copy folder/files twice. The same was happened to me while backup my external 1 TB Western Digital harddisk, so its hard to remember all 1 TB data. I have copied several files to PC which occupies too much space because of duplication of same files. I searched a lot and find one software winmerge, that I tried and seems useful. Sharing it, how you can use winmerge with your computer to compare and merge duplicate files/folders.

WinMerge is an Open Source differencing and merging tool for Windows.

Say if you want to compare one folder from your USB drive & another from your Local drive of your computer, you can choose both of them.Once you click okay, it will start comparing folders from your selected location.
I have created some identical files with similar name for trial. It will show comparison result with left date & right date option with extension option.SO it would be easier for you to find out for you which files are duplicate.
