To open an existing MegAlign Pro project (.msa):

Do any of the following:

  • From the Welcome tab, click Open Project on the left. Then use the options on the right to Open alignment project or open a recent document.

  • Drag an .msa file from the file explorer or desktop and drop it on an empty MegAlign Pro project window or tab.
  • Choose File > Open from the menu.
  • Click the Open a file tool ().
  • Press Ctrl/Cmd+O.

The following video (which launches, by design, at the 3:05 minute mark) demonstrates how to open existing MegAlign Pro and classic MegAlign projects.
