The files with the PA extension have various applications, some of them listed below:
Print Artist
The PA files in this application are used as project files for the Print Artist software.
Print Artist is a software originally developed by Sierra Entertainment, today owned by Nova Development and allows the user to make cards, calendars, stationery and other assorted crafts and then print them with their printer.
PowerPoint
In this use case, the PA file is a file extension commonly associated with Microsoft PowerPoint as an Add-in Format.
Microsoft PowerPoint is a presentation program, originally created in a company called Forethought, Inc., designed to provide business presentations, however, it has become widely used in many other communication situations, both in business and educational and other scopes.
Basically, the PA file extension is a plugin that adds functionalities to the program.
Files with the PA extension function only when added to the PowerPoint program and it is not recommended to open them manually.
