Seek and Replace 2
A place for every file, and every file in its place.
Seek and Replace 2 is a simple app that does only one thing (but it does it very well): it replaces files with new versions of them.
Select in Seek and Replace 2 the folder where you want to search, and then drag the files you want to search into the app. Seek and Replace 2 will replace all files with the same name in the search folder with the new version, matching them with the file name.
