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.

Sometimes due to the unacceptability by the program in which it was converted, its content is not properly visible.
