Types of data and file extension

by JimBb In reply to Types of data and file ex ...

A 10-point question that needs an answer that will never fit in this box...
There is no real relation, theoretically you can give any extension you like. However, by default most applications will look only for file-extensions that indicate a fileformat they can understand. Word for example will look for *.doc, *.dot and so on. I could create a file called something.jim, and if I want to open it I need to put the filter to "all files". For this reason it's easier to stick to the proposed extension.
Windows will open the application that is associatetd to a certain extension if you double-click a file in Explorer. Another reason to stick to the "default" extensions. But here too, just hold the shift and right-click a file and you can open any file in any application.
And about the types of data... Any application has its own format, most of the times the formats even differ between versions. In other words: the list is infinite. There are web sites that give you the defaultapplication per extension, http://camalott.com/~rebma/filex.html is an example.
