About PrjPcb
Since Protel DXP in 2002, an Altium design is a project: a .PrjPcb that lists its documents, the .SchDoc schematics, the .PcbDoc board and the libraries, with the settings for its outputs, its variants and how it checks itself.
The PrjPcb is text, in the sections of a Windows INI file: each document by its path from the project, then the project's parameters, its classes, its rules for checking the schematics and the files Altium makes for the factory. The design itself is in the documents it names.
Drop the project's folder on Filepeek and the board opens first, as it's made, from the top and from below, with every schematic and library in the file list beside it, each a click away. A schematic opens with the sheets it names. The .PrjPcb on its own opens as text.

Questions
How do I open an Altium project without Altium?
Drop the project's whole folder on this page. Its board opens first, as it's made, and its schematics and libraries are listed beside it, each a click away.
Why does my .PrjPcb open as text?
The project only names its documents, and the design is in them. On its own it opens as text, which shows the documents it lists. Drop it with its folder to see the board and the sheets.
Why is a sheet missing?
Each sheet is a .SchDoc of its own, and the project names it by its path. Drop the folder with every file the project lists, as Altium keeps them, and every sheet opens.
