easiest way to change the file extension using a program specifically designed to work with files.To open it in Windows can be a number of ways - for example, right-click "Start" button and the pop-up list of commands select "open Windows Explorer."
From the left column of the File Manager interface drive that hosts the object to rename and then, sequentially opening the folder in the same left-hand column, go to the directory containing the file.
If the extension of the desired object is not displayed in the file manager, open the drop-down list of the "Sort" on the left column of the Explorer and select "Folder and search opti
ons."If your OS is not in this list, expand the menu section "Tools" and select "Folder Options."In both cases, it opens the same window in which you need a list of options on the "View" - look for the line "Hide extensions for known file types."Remove the check mark that line and click OK.
clicking the desired file, right-click, select "rename", go to the end of the name (press the End) and correct extension.Press the Enter key you commit the changed file name.
The same operation can be done from the command line, even if the mapping file extension is disabled in the settings of Windows.Calling the command line simulator is implemented through dialogue startup programs - press simultaneously Win and R, to open the dialogue.Then type cmd, press Enter and the terminal command line will be opened.
Use the rename command to rename or abridged version of ren.This requires the full path and name of the object being edited, as well as a new file name extension (for the second parameter to specify the full path is not required).For example, if a file called someFile.doc placed in the root directory folder text disk F, then to change its extension to the doc to txt, enter the following command: ren F: extsomeFile.doc someFile.txt and pressing Enter.
