Do you use DropBox? Have you ever deleted a file and wished that you haven’t? Help may be at hand. Log into your DB account and then go to this page. Here you will see a list of your deleted files from the last 30 days. Click on the file and you can then select the file to undelete. Alternatively you can choose to permanently nuke the file if you have security concerns.
I don’t know if it is a new feature of db but by using this link first, clicking on the button and following the instructions, you can request a file on say a forum. By using the special link you get, anyone can upload a file(s) to the specially created folder even if they don’t have a db account. Haven’t tried it yet but that sounds awesome.
