File format associations control how Paint Shop Pro will interact with many types of file formats. You can have certain file formats automatically open in Paint Shop Pro. For example, when you associate the JPEG file format with Paint Shop Pro, all JPEG files will open in Paint Shop Pro when you double-click them from the Windows desktop. The associated JPEG files will also display Paint Shop Pro icons. For a list of supported file formats, see Paint Shop Pro 9 Supported File Formats.
