The File extension basically represents the type of file that appears after the name of the file i.e. quehow.html, here the “.html” is the extension of the file and can be changed easily.
The motive behind changing the file extension is that, it could also be readable by other programs, in which it is changed. Below are the steps that explain how to change a file extension in windows 7 by performing, few simple clicks on computer.
Steps to Change a File Extension in Windows 7
Step 1: Select the file and right click to copy it in another location, so that your original file will not be changed.
Step 2: Go to the desired destination where you want to copy, and right click on the free space and choose the “paste” option.
Step 3: File is now copied but you can see at the picture below that extension of file is hidden.
So, to enable the file extension follow this step otherwise refer to step 6 directly.
Click on “Start” and then go to “Control Panel”.
Step 4: Select “Appearance and Personalization”.
Step 5: Uncheck on “Hide extensions for known file types” and click on “Apply button”.
Step 6: Now, the extension of a file is visible, right click on it and select “Rename”.
Step 7: Then type the extension in which in you want to convert your file, I have typed “html” and you must make sure that extension is compatible.
Step 8: A Dialog box will appear, read it and click on “Yes”.
Step 9: File is now converted to html format. Open that file to check weather its content is visible or not.
Sometimes due to the unacceptability by the program in which it was converted, its content is not properly visible.
