Xiafunge for Mac

From Limit Point Software:

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. If the "from extension" is blank Xiafunge will append the "to extension" to any file without an extension. If the "to extension" is blank Xiafunge will delete the extension of any file that matches the "from extension."

Xiafunge is a member of the Limit Point Software "Utilities Bundle" which includes all software at http://www.limit-point.com/Utilities.html. A single donation unlocks all the utility software, upgrades are always free and new products always included.
