Hallo, my next topic, is there any well-made file duplicate finders, or maybe more for photos? Since I'm a wallpaper whore and like to collect as many wallpaper pictures as I can. Is there one though that actually looks on the content of the picture and not just checking the file name or date? Share your experiences or advice on which one you may recommend. Please and thank you.

You could use file size in bytes as a standard of measure, but it won't help in cases of false positives (unlikely) and different scales of the same picture, although detection of similar pictures is possible as shown through numerous web services such as IQDB and TinEye. I just don't know if such a standalone application exists.

picasa -> tools -> experimental -> find duplicates.

Easycleaner has a duplicate file search, but that's based on exact duplicates.

I just manually do it.

I'm using ACDSee Pro 2.5 for all my photo organizing needs. It's awesome for quickly browsing and/or (batch) editing a large amount of pictures and also has a duplicate finder. But afaik it finds only exact duplicates, not similars.

Picasa is probably your best bet. It appears to also be able to find similar pictures.

I use this. Only works for images though.

Yeah, Picasa seems to work well. Thanks a lot guys.
