Dropbox Bug Restores Really Old Deleted Files

A disturbing event occurred this week when hundreds of old, previously deleted files started appearing in my Dropbox.com folder. Fortunately, I removed them from the folder before the contents exceeded my capacity. Some of the files dated back to 2011 and some even before that. I was fairly busy and put off examining the files when notices started appearing in the news stream about the restoration of the files and attributing it to a "bug." For Dropbox.com it could have been a very "convenient" bug had a number of the people faced with the problem been told to pay for more storage.

After carefully checking to make sure I was not going to delete any valuable files, the duplicates all went in the trash.
