Services like Dropbox and Box still have large user bases (for now) and those files need to go somewhere. If you’re worrying about all the photos and files you keep on these services, don’t just yet. That’s a separate task all on its own.
For now, just explain how you use them and what you want done. For example, you can say “I was a very active Dropbox user for many years before transitioning to Google Drive. You can disconnect the account on my computer and everything in those folders will remain intact. Add those to the rest of my digital files, which should be sorted and stored in one place.” (Again, we’ll do this in another task)
Identify all your cloud-based storage accounts, the level of importance for each account, what should be done with them, and how you plan on granting access. If you use a password manager you can write it directly in the notes field, if you use a digital document you can put it there, and last but not least you can put it in the Digital Accounts section of your Everplan.
