how to change file formet in pc

File extensions tell your computer what a file is and what types of software programs on your computer should open the file. The easiest was to change a file's extension is to save the file as a different file type from within a software program. Changing the file extension in the file name won't change the file type, but will cause the computer to misidentify the file. In Windows and Mac OS X, file extensions are often hidden. This article describes how to save a file as another file type in almost any software program, as well as how to make the file extension visible in Windows and Mac OS X.
