From the developer: "SwapShaker is a powerful file manager for Kazaa, Morpheus, Grokster, AudioGalaxy, LimeWire, and other file sharing services. The program is a flexible tool which can perform a wide variety of functions on shared files including moving files from shared directories within 24 hours to reduce legal liabilities, automatically playing mp3 files after they are downloaded, and moving old files from a shared directory once it reaches a specified size. SwapShaker features a friendly interface and file rules are easily defined similar to message rules in an email client."
