For example, if you're converting from Quicken 2015, the subfolder is named \Q15FILES. If you ever need them again, you can find them in the Quicken\QXXFILES folder, where XX equals the last two digits of the number of the Quicken version you used before conversion. As a safeguard, Quicken backs up your original data files in the same folder as the converted files are. When you update a file, you will no longer be able to use it in the previous version of Quicken. You can also move Quicken files between computers. If you need help determining where another data file is, Quicken can help you find a file. Quicken displays the folder containing the current data file (the Quickenfolder by default) so you can select the data file you want to convert. If you have additional files on this computer to update, choose File menu > Open Quicken File. When you first started Quicken for Windows, it looked for the last Quicken data file you used and walked you through the process of converting it.
