• Sage 50 data is stored in a MySQL database.
• Each database consists of a SAI file that contains profile information about your company data, and a folder with an . SAJ folder that contains your actual company data, including financials and transactions

• In order for your data file to open, both the SAI file and the . SAJ folder must be stored on your computer on the same directory or location
• To open your data file, all you need is to double-click on the SAI file and you can access your data file
• The SAI file is only a shortcut to let Sage 50 know to open the .SAJ data in the same folder the SAI and .SAJ is located in
• If you rename the SAI file dissimilar to the name of the SAJ folder, the data will not open

• in the example above, double clicking on Test123.SAI will tell Sage 50 to find a database named Test123.SAJ instead of Test.SAJ
