A PostScript page description saved with a .plt extension (ISR Caddsman plot files do this). Not the HP-GL plotter format that shares the .plt extension - Filestar converts it like any PostScript file, e.g. to PDF.
The Portable Document Format (PDF) is a versatile file type designed to present documents in a manner independent of application software, hardware, and operating systems. Created by Adobe in the 1990s, PDF files can encapsulate text, fonts, images, and even interactive elements like hyperlinks, forms, and multimedia content. This format is widely used for its ability to preserve the original formatting of a document, ensuring that it can be viewed and printed as intended across different platforms.
