THINK Pascal was a Pascal compiler and integrated development environment originally developed by THINK Technologies and later published by Symantec for classic Macintosh systems.
A QPRJ file stores project information used by THINK Pascal, such as the organization of a Pascal programming project and the files or settings needed to build it. It belongs to the project rather than being a standalone source-code file.
THINK Pascal and the QPRJ format are legacy technologies and are no longer in regular use. They are associated with classic Macintosh software rather than current macOS development tools.
Open the .qprj file with THINK Pascal on a compatible classic Macintosh system. Current versions of macOS do not run classic Macintosh software natively, so a suitable vintage system or emulator may be required.
QPRJ files are project files for THINK Pascal rather than standalone source-code files. If you need to migrate a project, recover its Pascal source files and recreate the project in a compatible development environment; the QPRJ project structure may not transfer directly.
