Poor help and untrustworthy results

The help is really thin on this product and several important command/status fields are not defined anywhere on their online help that I could find. You must have 100% confidence in something you’re using to handle your files—I don’t. I tried to compare (never got nerve to sync) four different drives that were mostly the same. This software found missing files that were not missing and vice versa. It also didn’t flag missing files to be copied consistently. In all fairness, I also downloaded a trial of a more expensive compare app not on the Apple store. It wasn’t totally consistent either and comparing the same two drives gave different results with the two apps. Sync is hard, I’m not sure anyone does it perfectly. But I need better than I’ve found.

FYI I was trying to restore my Mac mini disk after a failure of an external SSD boot disk that failed after a month of use. The drive failed and I didn’t notice that the mini had at some point reverted to booting from internal HD. So I had some new and old files on HD. I was able to put the SSD in another enclosure (SSD itself was OK) and it had a mix of new and not up to date files. I also took four days to download the backup from my auto online backup service. So these files were mostly the same. The two apps along with Finder and Find Any File were used to compare the different versions. Constency was not a word to describe the results. Regretably, the online backup service was the worst copy. Word to the wise. Do archival copy saves not file syncs for backups.
