Today, Dropbox keeps these deleted files and old file versions ("undo history") forever. For many people this creates clutter, and it also wastes space.
Because of this, beginning August 1st, our new policy will be to keep 30 days of undo history. If you’d like to have unlimited undo history, then you need to upgrade to one of our paid accounts.

以上是Dropbox的新邮件通知.大概意思是对于免费用户,已删除文件最长只保留30天.如果要永久保留只能升级到付费的版本.不过对于免费用户来说我想一般的删除文件保留30也是可以实现日常工作的需求了.
