Are you backing up your files? If not, you’ll someday wish that you had. Flash drives are cheap. Keep one dedicated to backup and put all of your documents, photos, and data files from applications like Quicken on there every day, if possible. No need to overwrite files that haven’t been charged, but copy over the ones that have, as well as the new ones.
I lost around a hundred cartoons in the 90’s due to not backing up. Now, I back up in two places at home, and also remotely. When it comes to backup, there’s no such thing as too much.
