I'm surprised that DiskState was not one of the duplicate file finders. It uses MD5 signatures to compare exact duplicates either on a single folder on one hard drive or other folders across multiple drives. It has many other features that make it a valuable tool that I have been using for many years. Because it uses a MD5 signature, it cannot detect pictures that are essentially the same, but have minor differences.

If I say this Scooter Software app is the second most useful utility besides Windows Explorer or one of its many clones, I am not exaggerating one bit. Especially for someone who programs devices and needs to track changes on a daily basis. It's also great for doing incremental backups with the ability to synchronize in a custom semi-automated fashion. I know that there are some great configuration management apps that will allow you to back out to a more stable version when things start crashing. But if you're operating on a shoestring budget and you don't mind creative and inventive solutions that can be a useful substitute, then Beyond Compare is a useful and often versatile all-around performer.
