In the Windows operating system, at default settings, extensions for registered file types are hidden. Therefore, it often becomes necessary to find out what extension a file has.
Windows does not display registered file types, the user only sees the file name. These are the most file types in the operating system.
In order to get information about what extension a given file has in Windows, you need to right-click on the file. In the context menu, select “Properties”. In the “Properties” window that opens, in the “General” tab, the user will see the file type.
The icons of some files in Windows may look similar to each other, so enabling the display of file types makes sense for two reasons: for convenience and for security purposes.
Many antiviruses recommend displaying file extensions for greater security, as viruses can use harmless file icons. The user sees a familiar file type, runs it, and that file has a completely different extension.
For example, files with the extension “.torrent” and “torrent.exe” are often found on the Internet. Externally, the icons are very similar. Therefore, after launching such a file, an inexperienced user runs the risk of downloading to his computer something completely different from what he was going to download (movie, game, program, etc.). If the file extensions were displayed in the system, then it would be immediately obvious that the file with the “.exe” extension is disguised as a different file type.
You can enable the display of file extensions in the operating system using several methods: the first method is universal for Windows 7, Windows 8, Windows 8.1, Windows 10, the second method works separately in Windows 7 and separately in Windows 10, Windows 8.1, Windows 8.
