Seems to work

I read some of the reviews saying it didn’t work, but gave it a try anyhow. As near as I can tell, it seems to have done the job. It identified over 1 GB in duplicate files, I compared a few, verified that they were truly dups in different folders, let it move them to the trash, saw them all in the trash, then emptied the trash. Seemed to work fine for me. Seems like one of those programs you’ll use once and be done with. There’s a paid version, but the free version seemed to work well enough for me.
