File types

File type is a generalized classification of any file, which, as the main criterion for dividing to the groups, uses information about the contents of these files and extensions of their names. There are several main types: graphic (for example, JPG, GIF, PNG), text (TXT, RTF, DOC), archives (ZIP, RAR, 7Z), library (DLL), etc.

Usually, Windows can only detect the most common files of a certain type. For example, system "understands" only JPG, GIF, PNG, BMP, and some others (about ten) of the graphic files. Then, as there are several dozen of image formats!

Unknown file formats often have an extension that tells us the name of the program, which allows you to open files of that type. However, this is, alas, not always. The developers, for example, usually have a practice of giving a new names, enhanced with a hint of that information is contained in the file...

In any case, if you do not know how to open an unknown file, you can proceed in two ways. The first is to find a reference to the file extension in the Internet (for example, "open XML"). Maybe not with the first try, but you will find the information you need. The second way is to use a special applications.
