Disable file extension check

Hello,

Is there a way to disable the "Are you sure?" warning when you change file extensions in OS 10.5.7?

The server at my workplace only recognises one file extension (I don't know why, I just know that's the way it works). And I need to repeatedly change file names.

For example: The file MAG.feature_v1.doc has to be MAG.feature_v1 when we save it on our server.

When it's changed we need to change the filename to MAG.feature_v2, and the warning pops up.

I'm tired of clicking that confirm button 20 times a day, so is there a way around it?

Thanks.
