What is a UXF file?

A UXF file is a model interchange file saved in the UML eXchange Format (UXF). It contains Unified Modeling Language (UML) elements in XML format that make up a diagram. UML files are commonly used in the software engineering field to visualize the structure of an application or system.

You can open a UXF file with various programs, such as UMLet, which uses UXF as a native file format. You can also open UXF files with a text editor since they are stored in XML.

NOTE: UML was designed to standardize the encoding, publishing, accessing, and exchanging of UML models. It was originally developed from 1994 to 1996 by a team of engineers at Rational Software. It was then adopted as a standard by the Object Management Group (OMG) in 1997.
