I'm so glad I resisted the urge to buy this app when it first came out a couple of years ago. Don't get me wrong, it has a gorgeous interface and it does give you a fairly smooth way to browse your files, BUT that is ALL you can do: browse. You can't delete, move, or copy between folders; you can't flag, group, or otherwise manager images, you can't assign ratings or edit in any way, shape, or form. What a joke! The most gorgeous interface in the world can't make up for such a lack of basic functionality. There are free apps that can do more than FileBrowse.
And considering the glacial pace of updates (there have only been two measly .1 releases in 2 years) and the $25.00 price tag, this app is ridiculously overpriced. I feel bad for the people who've wasted money on this thing.
