A file with a DSK file extension is a disk image file created with an older disk imaging tool. Usually, a DSK file is an image of a 3.5 inch floppy disk. A disk image application is required to extract files from a DSK file. WinImage is a Windows disk imaging application that creates DSK images and extracts files from a DSK image. The application is free and can be downloaded from the winimage.com website.
Open the WinImage application.
