What is a QAF file

QAF files mostly belong to AutoCAD, Creo. QAF files are auxiliary files used in CAD systems to enhance workflow efficiency. They come in two main variations based on their internal format.

In one case, the file uses the JFIF format as a Quick Attach File in Autodesk AutoCAD. This variant functions as a thumbnail image file, offering fast preview access.

The other variant employs the XML format as a Quick Access File in PTC Creo Parametric. It stores structured CAD metadata that aids in rapid file information retrieval.
