I was using it to compare two relatively large volumes. But 46GB of memory and 20GB of swap file usage later, I killed it. Waste of time.

All this Lite version does is say, after a Looooooong scan is that there are differences, but then when I manually review some of the data in flie explorer, some of those differences were just file modify dates (meaning when it was wrote to that folder).To actually see if folders were different I had to use a completely different app.The intent of a Lite version is to intice you into buying the full version... Yes Agreed, but given I had to use a competitor solution to actually understand the results of this app,..... I ended up just sticking with their product and upgrading to their full version.Also another massive issue with this app is that if you click anything, it suddenly ditches the existing result and starts its long re-scan all over again.For a Lite experience this was poor, and it turned me away from considering the full version very quickly.

This app requires another app, FileMerge, in order to actually tell you anything about the difference between the files. Otherwise, the error is simply, “These two files are different. They have different content.” and there is a button, “Compare with FileMerge…” But even when I have FileMerge (which is a tool in Xcode) installed, FileMerge fails to load the two files I’m trying to “diff”. I sent a report of the problem to Apple today. I will update this, if the problem is resolved...,

Highly recommended. Thanks for your good work. Very efficient, fast, effective program.
