Ignore the message, its only a nag, you're the boss of the computer.

Remember, if you change the file extension you won't be able to open it in the application which you normally use for that file, but you can always change it back.

If you are in Windows Explorer it depends on the View settings. If you can see file extensions such as .doc or .jpg and you rename the file you should use the same extension after you rename the file. This ensures that the programme that created the file e.g. Word can open the file again.

If you are changing the name of a lot of files adding the same extension every time becomes a drag. You need to change the View properties to "Hide file extensions of known types" In XP you go to Control Panel>Folder Options and under Advanced Options scroll down and tick the relevant box. I think it`s the same in Windows 2000. Otherwise, If I remember, in Explorer go to View>Options and look for a similar tick box.

Oh I forgot - the computer then puts in the same extension as previous when you rename it but it`s hidden from view. Unclick the option again and you`ll see what I mean.

"how can i correct this."

The answer is to make sure, when renaming, that you keep the existing extension as part of the name, with no added full stops.

e.g. if the original is called,


don't change it to,

Change it instead to

Photo of Fred.jpg

Dont change it to,

Photo of Fred 25.12.04

because then it thinks the extension is .04

Hope this helps.
