The need to display a file extension can be caused by both security reasons and the need to change this very extension. This function does not require the use of additional programs or learning programming languages.
Instructions
Step 1
The full name of the extension sounds like "file name extension". The task of the extension is to determine the format of the selected file and select a program to open it. Visually, the extension is defined as the last characters after a period, followed by a file name. For example, picture.ipg means a graphic file named "picture" saved in.
Step 2
When installing the operating system for the first time, file extensions may be hidden for security reasons. Accidentally or intentionally removing the file extension makes it completely useless, since the OS cannot choose the program that can open this file. However, the function of displaying extensions is built-in and can be easily activated by the user. To do this, open any folder and expand the "Tools" menu of the top toolbar of the window of the application being used.
Step 3
Select "Folder Options" and go to the "View" tab in the dialog box that opens. Uncheck the box next to "Hide extensions for registered file types" in the "Advanced options" section and confirm saving the changes by clicking OK.
Step 4
In Windows versions 7 or Vista, there is a slightly different method to enable the display of file extensions. Launch the Windows Explorer application and open the Organize menu in the program window that opens. Specify the "Folder and Search Options" command and go to the "View" tab in the new dialog box. Uncheck the box next to "Hide extensions for registered file types" in the directory of the "Additional parameters" group and confirm the application of the changes by clicking OK. This action will cause the extensions to be displayed when viewing the selected files.
