File format associations control how PaintShop Pro interacts with many types of file formats. For a full list of supported file formats, see Files supported by PaintShop Pro.
Adding and removing file format associations
You can have certain file formats automatically open in PaintShop Pro. For example, when you associate the JPEG file format with PaintShop Pro, all JPEG files open in PaintShop Pro when you double-click them from the Windows desktop. The associated JPEG files also display PaintShop Pro icons.
Changing file format extensions
File format extension changes do not take effect until the next time you start PaintShop Pro. File extensions that have been associated with PaintShop Pro will have an asterisk (*) after the name.
What if I want to open a file in another program?
When you associate a file format with PaintShop Pro, you can still open the file in other programs by using the Open command in the program of your choice.
