FileName Extreme has been release on the Apple AppStore by Holy Mackerel Software.
FileName Extreme is a 64-bit Xojo application for renaming file names, folders and extensions based on their internal picture and audio metadata. It also allows over 30 renaming types including case, remove, find and replace, sequential numbering, hashes and truncation.
Apart from renaming you can export reports of your file data to CSV, PDF, Tab and XML. It uses many MBS functions to get access to additional file data, RegEx, Sparkle updates and SQLite databases. It uses threads to keep the interface responsive. It uses Einhugur Window Splitters to keep the interface flexible. It uses the Rowlands/Tempelman code for Apple AppStore Receipt verification.
Of particular interest to many may be the ability to export the EXIF (Mac only) and Audio metadata including iTunes Artwork and Lyrics.
The application is available for download on the web site for Macintosh, Windows and Linux. It is also available from the Mac AppStore and has been submitted to the Windows AppStore as a Centennial App.
