I mistakenly deleted the D:Data drive from Windows File Explorer and lost all of my Dropbox folders and files. I thought a D drive would be an external drive and that all of my files would still be in the DB cloud. But no, they're all gone but worse than that, they did not go to the Deleted folder, they just disappeared, so it doesn't look as if I can restore them. We have the Basic plan with 2TB of storage so I ought to be able to restore deleted files but I didn't delete them from an open file, I deleted folders from Windows Explorer. Have I permanently lost all my files?
