Changing file associations in Windows XP and Windows Vista can be a tedious task. You first have to load the Folder Options in the Tools menu, select the File Types tab afterward, wait for the list to load, scroll down until you find the file type that you want to change, click on the change button to change the file association and browse the computer for the new application. You better take a day off if you want to change the associations of several file types.
Types on the other hand is a lightweight portable Open-Source software that runs on Windows XP and Windows Vista that makes it a tad easier to change file associations in both operating systems. It comes with a window that can actually be changed in size which means that it is possible to display virtually all file extensions on
the screen at the same time.
The default application can be changed easily. Other options include changingthe icon of the file type and deleting obsolete ones from the system.
