This week's batch of third-party Leopard software updates begins with Tidy Up!, Snapz Pro X, and Garage Sale.

Tidy Up! is a duplicate finder and disk tidying utility. Users can search for duplicate files and packages by a range of parameters, including owner application, content, type, creator; or tag, duration and bit rate of MP3s and AACs audio files. The software will also search the contents of iTunes, iPod and iPhoto databases and search Mail messages.

Now Leopard-compatible, the new version is faster than before and supports multi-tasking, it also implements a feature that ensure users don't accidentally delete the last copy of any file found using the software.

Ambrosia Software has introduced its Leopard-compatible Snapz Pro X 2.1.2. The update is free to all registered users of Snapz Pro X 2.0.x and is available for download here.

Snapz Pro X has become industry standard for desktop video and screen shot captures, and is used by many companies (including Apple) to produce their tutorial movies.

eBay auction software GarageSale has also been updated adding eight new templates and fixing several bugs, including one for Mac OS X Leopard.
