File Extension


There may be a file extension the closing of the document that helps determine the kind of document in systems for example Microsoft Windows. In Microsoft Windows, the file extension is just a time that’s usually accompanied by three figures, but can also be two, one, or four characters long.

Some file systems implement filename extensions as a feature of the file system itself, and may limit the length and format of the extension, while others treat filename extensions as part of the filename without special distinction.For Example, the filename “myfile.txt” comes with an expansion of “.txt”, which is really a file extension related to text files.
