What Is File Type Association?

A file association associates a file with a specific application that is able to open the file. Similarly, a file type association associates a type of files with a corresponding application. The file type is commonly determined by the filename extension. For example, the .docx files may be associated with Microsoft Word.

A single file extension might have more than one association for performing different actions. Specifically speaking, an application might be associated with a file extension to open this type of files, but another program might also be associated to open and edit the files.

File type association is very helpful, but it might get corrupted. As a result, a file will be opened with another application that is not suitable. In this case, you should remove file type associations for the file to stop opening the file with the associated app by default.
