For the price it’s “adequate"

This is a fairly good tool, especially for it’s $0.99 price, but not nearly as robust as I need it to be. Like virtually all other OS X tools for deduping, this fails to offer sufficient selection criteria for determining which duplicates should be removed. It’s auto-select, while great for novice users, would NEVER be used by a serious user because the entire purpose of deduping is to keep the files YOU want to keep and get rid of the others. Auto-select seems quite indiscriminate in it’s selection process. I would expect a de-duplication tool would group duplicate files and then allow me to select in each group based on path length, filename length, file size, age, text string and then allow me to invert my selections, protect certain folders (so they’re never deleted), etc. Duplicate Cleaner Pro for Windows is one of the better tools… wish they offered a Mac version! I’d pay $30 for a de-duping tool that was as robust this!
