GURPS Character Assistant is character-management software from Steve Jackson Games for the Generic Universal RolePlaying System (GURPS). The GCA4PARTY file extension identifies one of the application's native data files.
A GCA4PARTY file stores information about a GURPS party for use in GURPS Character Assistant. It is part of the program's character and campaign data rather than a general-purpose document format.
The format is associated with the Microsoft Windows version of GURPS Character Assistant. It is intended for use within that software and may not be supported by other applications.
Open a GCA4PARTY file in GURPS Character Assistant on Microsoft Windows. Use the program's file-opening or party-management commands to load it; opening the file directly may also work if Windows has associated the extension with the application.
If GURPS Character Assistant is not installed, the file may not be readable because it uses the program's native data format.
Open the GCA4PARTY file in GURPS Character Assistant and use any save or export options provided by the program for the data you need.
