Hi, Terri.
A Quicken "file" is actually a set of related files, all with the same name and different extensions. The number of files in the set, and the extensions, can vary, depending on how YOU use Quicken. There will always be a file with the extension .qdf; there may also be files with extensions like .qel or .qtx and others; I also have .idx and .qph. In any case, Quicken refers to the set of files as "a file".
The default name for all the files is QDATA, but you can choose any name you like. Your main file might be Terri.qdf, with other files named Terri.qel, for example. In addition to backups that you make, Quicken will automatically create a backup set each week; these will be in a folder that Quicken creates and names BACKUP (all CAPS) as a subfolder under the folder that holds your main data set (Terri.qdf ? ).
In addition to the automatic backups, you may (and should) make periodic backups to one or more locations of your choice. At least one backup set should be on saved separately from your computer. This can be on a CD, a USB thumb drive or a removable hard drive - or even on a floppy, if your fileset is small. Your backup can be in a separate folder or on a separate hard drive in your computer, but if your computer gets stolen, your backup is gone, too. :>(
