FileBrowse is a new, easy-to-use file/media browser for Mac OS X with many unique features, such as 3D icons/thumbnails, large in-context previews, and powerful grouping and sorting. 3D Icons/Thumbnails The standard file browser on the Mac is the Finder, which can show thumbnails of image files, but shows all other files and folders as standard icons. Because all items of a certain type have the same icon, it’s hard to distinguish the items. The icons don’t give any clue about the specific contents of the files and folders.
