TypeShuffler is a drag and drop utility that allows you to change the creator code, file type, and file extension of files. It also provides you with a configurable database of creator codes so that you can quickly change files to your preferred codes, types, and extensions.
You can drop any number of files onto the TypeShuffler application to change their type information. In addition, you can also drop any number of folders containing files.
When TypeShuffler is first opened, it will display the type information of the first file that it finds among the files that were dropped onto it. In the top/left corner of the window you will also see the icon that is associated with the current type information. This icon will be updated whenever the type information is changed.
