The DMSP file is a Roxio PhotoSuite project file. Roxio PhotoSuite is photo-editing software from Roxio, and the project file saves the work so it can be reopened and continued in the application.
A DMSP file is a project document rather than a general-purpose image file. It belongs to the Roxio PhotoSuite project workflow and is associated with Roxio Creator NXT on Microsoft Windows. The format is intended for use within Roxio software, not as a broadly interchangeable image format.
Open the .dmsp file with Roxio Creator NXT on Microsoft Windows. Use the program's Open command and select the file, or open the file from Windows if the DMSP file association is configured.
Open the project in Roxio Creator NXT and export or save the completed photo in an image format supported by the program.
