All known file formats using extension .PRM

While Parameter File is a popular type of PRM-file, we know of 2 different uses of the .PRM file extension. Different software may use files with the same extension for different types of data.

The Print Shop Deluxe Graphic

The Print Shop Deluxe graphic file with extension .PRM is a proprietary graphics format used by Broderbund's The Print Shop software. It belongs to the Print Shop Deluxe Companion add-on and stores individual graphic elements (clip art) that users can import into page layouts like greeting cards, signs, banners or other design components.

Within the workflow of The Print Shop, these .PRM files are written when the program's Companion module installs or saves its built-in graphic libraries; they are read when a user inserts clip art graphics from the Companion's library into a project. They are not project files themselves, but reusable graphical resources.

Each .PRM file begins with the ASCII signature "PSDeluxe.pcc" at offset zero and contains the keyword GRAPHICS somewhere within the file, which allows recognition by TrID or other signature-based identification tools.
