PSPMASK is a proprietary format of Corel PaintShop Pro and such files include "masks" used for protecting certain areas of an image from editing. Masks can be displayed in various shades of gray that cover the actual image, where the darkest areas are most protected and white ones are unprotected. PSPMASK files can only be opened using programs from the Corel pack.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple PSPMASK files as once.
