R Green Blue has released
FileBrowse, a file and media browser for Mac OS X. It costs $25.
FileBrowse lets you view files and media content on your Mac using features lacking in the Finder, such as thumbnails for most common file types, including images, movies, songs, PDF, RTF, Word documents, and Web pages. The software renders 3D icons and thumbnails using OpenGL. Folder icons show miniature icons and thumbnails of the items inside, and large previews are available for most common file types. The software also allows grouping and sorting by kind, date, color label, artist, album, camera and other attributes.
A 30-day trial version is available for download. System requirements call for Mac OS X v10.4 or later; FileBrowse is a Universal binary that runs natively on Intel and PowerPC-based Macs.
