Types is a small configuration application that lets you manage filenames, icons, and other file and folder properties. It also allows you to modify context menus. There are several user-supported language ports of Types, a nice feature.
Types installs quickly and has a very simple interface that lets you navigate to different folders and click on files or folders to examine their basic properties and modify them, or delete the files. The problem with Types is that it is very basic and offers limited functionality. There are other applications that give you more control and more options, but Types does what it says it will.
For what it does, Types works. For some, it will be enough for them to handle their icons and file properties, but most Windows users will want more capabilities and functionality.
