The file name EXTENSION (spelling counts in Web searches!) identifies the format of the file and the program that should normally open it. For example, a file with extension .DOC is in Word 97-2004 format and should normally be opened by Microsoft Word. Many programs can open files that are normally opened by another program. For example, most word processors can open .DOC files - a market requirement because there are so many Word users. To do this, it may be necessary to modify system settings (the software may provide users help in doing this) or to launch the application first, then open the file from within it. File name extensions were originally limited to three characters in DOS. Early versions of Windows, which were built on a DOS core, continued this limitation. Many extensions are longer today, such as the .DOCX format for Word documents introduced with Word 2007/2008*. Prior to OS X, the Mac OS did not use file extensions though it allowed them so files could be easily exchanged with DOS/Windows systems. It used internal "type" and "creator" data instead. With the introduction of OS X, the Mac OS uses them in much the same was as do Windows systems: to select the default program to open a file. _____________________________ *Word 2007 is the Windows version; 2008 is the Mac OS version.
You're computer is regonising a file as an "Unknown File" only because it has no understanding of that file extention. Right click the file and select "Properties", find the extention name (Eg, .exe) and search for software that will read that extention name. If you're having further problems consult someone on a Technical Help Forum.
The file extention of any application on a computer is: '.exe' .exe = simply means executable.
What is in it.
A console is saved in a file with an .msc file extention, and a snap-in in a console can itself be a console.
File extention (.bak, .backup or similar) Size, depending on how big the backup is.. it can be as big as two terabytes (tb).
The name of the file is either 'Temp' or 'Locals'. These files are temporary in nature and keep the association between computer names and IP addresses. Since IP settings and computer names change often, the file simply reflects the latest settings when saved.
Do a search for the file name.

The file extension is the two, three, or more letter code that is after the period in a computer file name. It is used to "tell" the computer what type of file it is and what program on your computer will "open" or "run" it.
