Vista Tutorial - File Extension Type Icon - Change

Information

This will show you how to change the default icon for a file extension type of your choice to whatever icon you want it to be displayed as in Windows Explorer instead.

NOTE

This will change all of the icons for that file extension type in Vista, not just the shortcuts of them. To see what the file extension is for a file, see: How to Show and Change a File Name Extension in Vista Some Common Icon Locations: Unknown file icon - HKEY_CLASSES_ROOT\Unknown\DefaultIcon Folder icon - HKEY_CLASSES_ROOT\Folder DefaultIcon

Tip

You can also use the free configuration utilty program named Types to easily change a file extension icon to what you like in a easy to use window instead of through the registry.

WARNING

You will need to use a 256x256 pixel icon that was made for Vista for them to display properly at all of the available icon view sizes in Vista. For more about Vista icons, see: Icons in Windows Vista Some programs will automatically reset the default file extension icon back to the one it uses even after you have changed it. This will not work for these. If you change the default program for the file extension, it will also change the icon for it to whatever the program you selected as the new default uses.

NOTE

For this tutorial, I am going to use just the file extensions .txt and .mp3 as an example. You can change any other files extension you like. Just substitute the file extension you want to change in the steps below instead.

1. Open the Start Menu.

2. In the white line (Start Search) area, type regedit and press Enter.

3. Click on Continue in the UAC prompt.

4. If Using the Default Program by Vista -
NOTE: You would use this option if you are using the default program that Vista uses to open the file extension.

A) In regedit, go to: (See screenshot below)
HKEY_CLASSES_ROOT\.txt
NOTE: Substitute .txt with the file extension you want to change instead.

B) In the right pane of the file extension, look at the Data value to the right of (Default). (See screenshot above)
NOTE: For example it is txtfile for the .txt file extension type.

C) Go to step 6.

5. If You Changed the Default Program -
NOTE: You would do this option if you have changed the program used to open the file extension to a 3rd party program instead of the one Vista used by default.

A) In regedit, go to: (See screenshot below)
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.mp3\Userchoice
NOTE: Substitute .mp3 with the file extension you want to change instead.

B) In the right pane, look at the Data value to the right of Progid. (See screenshot above)
NOTE: For example it is WMP11.AssocFile.MP3 for the .mp3 file extension type by default. Your value will vary depending on the default program you have to open this file extension.

6. In regedit, scroll past the file extensions and go to: (See screenshots below 7)
HKEY_CLASSES_ROOT\txtfile
NOTE: Substitute txtfile with the Data value from step 4B or 5B for the file extension you want to change instead.

7. Click on the arrow next to txtfile to expand the key (folder).
NOTE: Substitute txtfile with the Data value from step 4B or 5B for the file extension you want to change instead.

8. To Backup the Default File Extension Type Icon Settings -
NOTE: To restore the default file extension type icon settings from this created backup below, right click on the .reg backup file and click on Merge. Next, approve the merge and log off and log on to apply the change.

A) Right click on DefaultIcon and click on Export. (See screenshot below step 9)

B) Select a location to where you want to save the backup (reg file) at. (See screenshot below)

C) Type in a name and click on the Save button.
NOTE: Be sure to type in a name that is easily recognized by you for that file extension.

9. In the right pane of DefaultIcon, right click on (Default) and click on Modify. (See screenshot below)

10. Select Option One or Option Two below for what icon you want to replace the file extension icon with.

OPTION ONE:
Change File Extension Type Icon to a Saved Icon

A. Download and save a icon of your choice to a location you wish to store this icon at.
NOTE: See the Warning box at the top of this tutorial for about what kind of icon to use. The icon must stay at this location for as long as it is being used for the file extension.

B. After step 9 above, type in the full path of the icon file location from step A and click on OK. (See screenshot below)
NOTE: For example, I used a icon file on my desktop. Sometimes you will need to add ,0 (number zero) at the end of the full path for it to work. For the example below, C:\Users\User-Name\Desktop\txt file.ico,0

C. The registry will now look similar to this. (See screenshot below)

D. Go to step 11 below Option Two.

OPTION TWO:
Change File Extension Type Icon to another Vista Icon

A. Download and install the free program IconViewer.
NOTE: This program will add the Icons tab to files (ex: imageres.dll) that contain a icon library in them so you can see the icons available in it.

B. In Windows Explorer, navigate to C:\Windows\System32\imageres.dll and right click on imageres.dll and click on Properties.

C. Scroll through the icons and make note of the icon number of the one you want to use to replace the file extension icon with. (See screenshot below)

D. After you had made note of the icon number, close the Properties window and the Windows Explorer window.

E. After step 9 above, change the number after - at the end to the icon number in step C and click on OK. (See screenshot below)
NOTE: For example, I wanted to change the icon for the .txt file extension to be icon number 19 from step C instead. If you do not have %SystemRoot%\system 32\imageres.dll,-### in Modify, then change it to this with the number (ex: 19).

F. The registry will now look similar to this. (See screenshot below)

G. Continue to step 11 below.

11. Close Regedit.

12. Log off and log on, or restart the computer, to apply the changes.
NOTE: For the .txt file extension example, the left screenshot below is for after Option One, and the right screenshot is for after Option Two.
