There are two ways to manually open an Analysis file: from the Home Screen or in Analysis Mode. You can also automatically load the last Analysis file at startup. You set the default folder for Analysis files in the Analysis Options.
Under the Analysis header, select Open an existing analysis. The right side of the screen will be divided into two sections. From the top section you can select your most recent Analysis file. The bottom section lists files you've opened or created in the past. If you don't see the file you're looking for, click on the more files... selection in the bottom section.
Click on the Open Button in the Desktop Toolbar, or select Analysis | Open | Analysis. You can also select a recently-opened file from the list in the Analysis menu.
ValuSource Pro can automatically load the last Analysis file at startup. See Startup Options.
