Files in the Deleted Files section do not count against your storage quota. Once a file is deleted, you can no longer see it at www.dropbox.com/home. Dropbox saves a version of that file for 30 days.
Copy the files onto your computer and then delete them from Dropbox. That way you will still have saved whatever files you copied and they will be out of your Dropbox account.
Look for shared folders (that you're a member of) that might not be syncing fully.
Users have spotted a new toggle in the Dropbox setting for third-party AI. This feature allows Dropbox's AI partners to access your files, which is necessary to integrate them with the model.
Warning! - You should double-check the:
Dropbox Preferences | Import | Camera Upload | Change AutoPlay Settings
because Dropbox will automatically change all your computer's Control Panel AutoPlay settings:
Control Panel\All Control Panel Items\AutoPlay
Warning! - Keep your Dropbox folder on your boot drive (probably C:).
When Dropbox does not detect your Dropbox folder, it will attempt to recreate it in it's default location (C:\Users\YourUserName\Dropbox).
Dropbox won't work correctly should the Dropbox folder ever become inaccessible.
