Open PSI File
A PSI extension file provides access to online help documentation for PrimalScript, a visual script development program.
PrimalScript is an industry leading Universal Script Environment (USE) developed by SAPIEN.
This software works as a system, database or network administrator, web developer or end-user developer.
It is a suite that has multiple technologies, languages and file formats at the same time.
The PSI file contains a topic header, file description, and links to online help.
PrimalScript's Nexis window displays the PSI file data as a folder, or as a directory tree.
When opened, the content of the PSI file is displayed as a dropdown list of text and links.
