Planning ahead is always a good thing. If you plan and follow through you can usually prevent most major problems.
Ancestral Quest allows you to designate where your files are stored. While there are default locations, you can choose to accept them or change them.
To change or add locations for all your files including a back-up file, go to "Tools" and then down to "Preferences":
Once there, click on the tab that says "Files and Folders":
At this point you are able to choose the locations for Databases, Import/Export, Backup, Reports and Web Pages. By clicking on the Browse button you can choose your specific location. Once you are done, click "OK" and you are brought back to your main family file data.
Adding the locate for your backup will help you know where they are always located. It is suggested that this be an additional device, either an external drive or a USB drive.
Enjoy the peace of mind knowing where all your files are saved to when working with Ancestral Quest.
