PlasTeX is a Python-based framework that processes LaTeX source and builds structured output. During processing, it can create a PAUX file containing auxiliary information used by the framework.
The file is a working file used as part of the PlasTeX processing workflow. PlasTeX can be used on Microsoft Windows, where PAUX files may be generated.
PAUX files are not generally intended for manual editing or distribution. They can be recreated when the associated LaTeX document is processed again.
A PAUX file is not normally opened independently. Run PlasTeX on the associated LaTeX source to use the file as part of document processing.
If inspection is necessary, a plain-text editor may be able to display its contents, but the file is intended for PlasTeX rather than manual editing.
A PAUX file is an auxiliary working file, not a document format intended for conversion. There is no usual reason to convert it directly.
To create usable output, process the original LaTeX source with PlasTeX. The PAUX file can be regenerated automatically when needed.
