From the developer:
Xiafunge is a utility for changing the extensions of files.
To use: Drag one or more folders (or files) on top of the Xiafunge application in the Finder or the main window. Xiafunge immediately begins to traverse the folders and all their subfolders changing the extension of all files that match the "from extension" to the specified "to extension." Use the Preferences window to configure the conversion.
