How to Change File Type in Vista

Windows operating system determines file types based on file extensions. An extension is a string after the period in the file name that is usually three characters in length (.doc, .pdf, for example). File types allow to establish a link with target applications (.doc links to Microsoft Word, for example). By default, Windows Vista Explorer displays file names without extensions that make changing file types a bit tricky.

Instructions

1. Open Windows Explorer and navigate to the file that should be changed.

2. Click "Tools" in Windows Explorer, and then "Folder Options."

3. Select "View" tab in the folder option window.

4. Scroll down the list under "Advanced Settings" and find the option "Hide extensions for known file types." Uncheck the box for this option and click "OK." Note: Windows Explorer now should display all file names with extensions.

5. Right-click on the file chosen in Step 1 and select "Rename" in pop-up menu.

6. Place the mouse cursor in the file-name box, which is now accessible for editing. Delete the current extension and type in the new one. Press "Enter" and then click "Yes" to confirm the change.
