Crashes each time AFTER running all day long.
The task assigned was to list duplicates in a ¾
empty 1 TB (boot) hard drive.

I finally got it to run to completion, but there are oddities and complaints.

Firstly, it did NOT just scan the volume thatI selected - it scanned an external HD as well. That partially explains the absurdly glacial pace.

The biggest problem is that this is a virtually featureless application. It does not create a text file to save, it has no ability to delete files. etc. etc.


Note: There is a delete button, but mine remains grayed out while selecting a listed file.


Please ignore my last comment re: the delete button.
Indeed it does work. I failed to tick the checkboxes.
Highlighting the files was not sufficient to the task.

Thanks for your feedback. Yes, it would scan all volumes because they are mounted on /volumes which reside on boot drive. Fixed on version 1.1.
