Works perfectly,

Great add for finding and removing duplicates. This app has saved me tons of space.

Great litle app for the money!!!

This is an app that has a lot of potential and it works great on local drives and attached USB drives for finding duplicates and lets you prioritize the deletion based on location, age and a lot of other cool features and I like the quotes that is fun and the auto select is the bomb and works excellently.

But I have 2 complaints about this product thats why I didn't give it a 5 star rating. It doesn't show you a status of which files it's scanning so you can see it's progressing. It would be nice to have a percentage of files scanned as well as it doesn't scan networked drives very well especially if they are large drives. I tried scanning my file server a 1TB partition because its a G5 Mac PPC processor and there isn't a version for PPC to run it locally. Another thing that would be nice is to be able to set the network bandwidth it can use as well as memory although this app already has a very small footprint and uses very little memory. I was thinking it would be nice to allow it to use as much memory as it could to complete the scan quicker.

All in all though my hats are off to the developers for this app. It doesn't ever crash or hang on me and again the auto select is awesome because I always find several hundred sometimes thousands of duplicates when I'm consolidating my photos, music and movies from 3 different computers into one place.

Oh and one last thing many other duplicate finders make you select which files you want to delete when you have thousands of files that would take me a week to select and delete them all. ****************************
