I have written about a way to manually repair file type associations in Windows by using two commands and the Windows command line. While this works in most cases and is certainly faster than using a software for the matter it has its limitations.
WAssociate is a software that is able to change file type associations of all file types in Windows. The software requires a little bit of knowledge of how file types are assigned in Windows but is well worth that time. It displays all known file types and their associations by pulling the data from the Windows registry.
It is possible to select the application that should be used to open the file type and to add additional parameters to the command as well. This is a good way to quickly fix several file type associations. It is possible to create new file type associations by typing the file extension in the ‘Extension’ form.
