If you are a Dropbox user, you might want to check your public folders. You might be inadvertantly sharing documents and photos with the rest of the world. By default, when you install Dropbox, there are two public folders that are publicly searcheable by search engines.
The most obvious shared folder is Public. That’s a no brainer. To my surprise, anything under the Photos folder is also searcheable by search engines. Here’s my case in point. Open this link. You will see thousands of search results of Dropbox users and their photos.
If you are going to use Dropbox to store photos and documents, do not use the Public and Photos folder. Unless you want to share it with the rest of the world. Place your photos and other documents in a separate folders instead.
If you want to share photos and documents, it’s better to share it privately with individuals, as opposed to having everyone access to your files. Credit to ghacks.net. Check out the comments on that article as well.
