What causes that Open/Save dialog?

Have you ever wondered why for some files you get the Open/Save dialog when you are saving an attachment in Outlook, and for others you don't?

Now you have the power!

1. Open Windows Explorer


2. Go to Tools and then Folder Options


3. On the File Types tab, select the extention type you are interested in and click Advanced


4. You'll notice a check box called Confirm open after download. If this is checked you will get the open/save dialog, if not it will just open with the registered handler.

The settings you change here are saved in HKEY_CLASSES_ROOT in the registry for each specific extension. For example, if you change the .txt extension, the changes are saved in the \txtfile key.

Cheers!
