There are many ways to open a previously saved project :

From the "File" menu, click on Open...

This function will show the "Open project" window. Select a file to open and click on the "Open" button.

 

Within the ...Active Takeoff\My Projects folder, you will find a folder for each saved project. Within each of these folders are an Active Takeoff project (qpl extension, red arrow) and the project's plan files (png extension, blue arrow). To open the project, click on the qpl file.

 

Recent projects can also be opened quickly from the "Recent projects" from the "File" menu or directly from the "Start" menu.

The Active Takeoff(.qpl) project icons can also be double-clicked or drag-and-dropped in the Active Takeoff interface when it is open.

 Finally, a .qpl (Active Takeoff save format) project file can be double-clicked from a Windows explorer. This operation will automatically start Active Takeoff.
