By default, automatic backups are in the BACKUP folder that's in the same folder with your Quicken data file. You can check by going to Edit—> Preference —> Backup —> Automatic backups Open/Change backup directory.
You can search for files the have an extension of .QDF or .QDF-backup. How did you loose your data?
@Dori - so just to confirm or clarify - were you using Quicken with all the active files being stored on your flash drive ? If you open Quicken, —> File —> look at the very bottom of the menu and it should show the location URL of the last 4 Quicken files you used …. where does it show them .. what drive letter & location path ?
Were you keeping your active Quicken data file on the micro drive? If so, that's a really bad idea. It should be on the computer hard drive and backed up to a micro drive or better a cloud drive. Have you searched your whole hard drive for any Quicken files? Do you get an error message trying to open the 2022 backup?
