- Description
- A PPSM file is a macro-enabled slide show created by Microsoft PowerPoint, a program that allows users to create slide shows and presentations. It contains a non-editable collection of slides. PPSM files are used for packaging view-only Open XML-based presentations, such as .PPTX files, for sharing with others.
- A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
