About STX files

The .STX extension represents a frustration common in digital archiving: one filename used by multiple, completely unrelated industries. Most frequently (approx. 43%), an .STX file is a PLC project archive generated by Schneider Electric's legacy PL7 Pro software. These files contain critical industrial logic and configuration data, yet they are often proprietary binaries or renamed ZIP containers that modern text editors cannot parse. This can create major obstacles for engineers trying to migrate old automation systems without maintaining a Windows XP virtual machine.

Alternatively, you may be dealing with a title overlay file from Pinnacle Studio, a video editing suite. In this context, the file stores text styling, animations, and layout data for video titles. These are strictly internal assets; you cannot upload an .STX directly to YouTube or view it in a media player. Other legacy formats include design files for Roland Dr. STIKA vinyl cutters or disc label projects from Roxio SureThing.

Best Conversion Targets:

For Industrial/PLC: Convert the documentation or logic readout to PDF for long-term archiving, or extract the contents (if acting as a container) to standard source files.
For Video/Pinnacle: Open the project in the original software and export the title frame as a transparent PNG or TIFF for use in other editors like Adobe Premiere.
For Vinyl/Roland: Convert legacy cutter designs to SVG or DXF to ensure compatibility with modern plotters.

The STX Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our STX converter.
