Introduction: Why You Might Want to Share a Dropbox Folder With Someone
It is a good idea to share a Dropbox folder with someone you trust. You can make one folder for your “personal” documents, and another to share with co-workers or family. If you don’t want the documents to live in your Dropbox folder, you can also share a folder by emailing a file. Here are some reasons why I think it’s good to share a Dropbox folder:
1. We all have sensitive/personal documents (e.g., tax documents, marriage certificates, maternity photos) that we’d rather NOT share with coworkers or family. If you do share a Dropbox folder with others, be sure to decide beforehand whether you want the other person to have access to read or modify these documents.[1]
2. It’s easy for co-workers to leave viruses on your computer due to their frequent logins on shared computers, drive-by downloads from websites and email attachments. There are hundreds of viruses available in the wild, and new ones are being released every week. Since sharing a Dropbox folder can potentially enable other people to download a virus into your computer, it’s important to think twice about whether you want your folder shared.
3. Dropbox is set up to sync everything (documents, pictures, videos) in your account to all the computers that you log-in on. You can access Dropbox on mobile devices or any computer with an internet connection (while you’re away from your desktop computer or laptop). If you share a Dropbox folder, anyone who has access to your computer will be able to access these documents on all the computers that you choose to sync with. Be warned that you can’t decide which files will sync with which laptops and mobile devices.
