DropBox synchronizes files across your internet connected devices. Windows, Mac, Linux doesn’t matter. iPhone, Android, iPad doesn’t matter. Stolen computer? No worries with Dropbox. Dropbox is a simple, effective file-synchronization tool that does what it is designed to do flawlessly. Many users set up an account simply as a backup tool. Works well in that mode, but there is so much more that you can use it for. You can share a file with someone else with only a few clicks. You are provided with 30 days of “undo” history, so that you can recover that file that you deleted two weeks ago by mistake.
