Greate tool!

The Hungry Ghost

This a great tool to find duplicates of files. The developer understands all the complexities and subtleties of duplicate files. This makes for a simple and easy to use app.
A couple of wish list items:
And although there's a great mechanism to filter files before you start, I'd like to be able to mark certain files to ignore (just per run of a comparison), that way items that I've decided should stay can go away and not clutter up my view while I try to find problem duplicate.

Not convenient at all


It looks like a well-built app for someone with a lot of time to invest in this but for a normal user, this app is very inconvenient to use. I keep getting errors that I don’t have authorization to delete certain things (not system files, rather PDFs I have on my desktop, etc). If this app was only a buck, I’d understand but for $15, no I don’t have the time for games. To charge such a price, I expected to get what I asked right upfront, not having to figure out this overly-simplistic UI that just doesn’t do what I need. Or if it does, it does a good job of hiding these options.

Not Compatible with OS X Sierra


I used this app for years and was well pleased, but when I upgraded my OS X to Sierra, Chipmunk stopped working.
One feature I found most useful was the ability to delete all duplicates found within a given folder. I have yet to find another app with this ability.
Hopefully the author will soon update this app so that it is compatible with Sierra.
