Files with the PSQ extension are documents created using the PostScript concatenative programming language developed by Adobe Systems and used mostly within desktop publishing. PostScript files are self-contained documents that follow the DSC (Document Structuring Conventions) set of standards.

The PostScript Graphic format is mostly used for saving documents which may contain text, raster graphics, vector graphics and a set of page formatting properties. Additionally, PSQ files contain printing instructions and a thumbnail image. This allows users to print the files directly using a PostScript compatible printer (equipped with onboard raster image processor) without having to open them in an application first.

How to open PSQ Files

PSQ files can be opened with many vector graphics editing programs and drawing applications making them a popular choice for image transfer across different operating systems.
