How to find same filenames (with different extensions) and delete all other files ?

[gidhap]

I want to clean up some directories with lots of pictures where (in the same directory) I have pairs with same name but different extensions (both to be kept), plus a lot of other files which I do not need any longer.

Example:
eagle.dng keep
eagle.RW2 keep
test1.jpg delete
bear.jpeg delete
moose.dng delete
caribou.RW2 delete

I am totally new to WinMerge and tried to play with filter but I don't get it yet. Any help appreciated

Unfortunately, WinMerge does not have the ability to find the same file names.

However, WinMerge can sort by file name, so if you disable Tree Mode and sort by file name, it will be easier to find the same file name.
