If you have multiple computers (and multiple Operating System platforms) like I do it is very useful to sync folders between them so you can access current information from any computer. With Dropbox you can even securely access these files from someone else’s computer using the Dropbox web service. Another very valuable capability is immediately sharing files with others via a shared folder. For distributing photos for example, this sure beats sending multiple emails and is quicker than uploading to online services.
Lifehacker has an article on even more things you can do with Dropbox including such innovative things as syncing passwords across computers and accessing shared portable applications.
Dropbox is free so try it out using this referral link to get extra storage space. It is simple to setup with just an online registration and installation of software that works on Windows, Linux, and Mac.
I am sure you will like it since it is easy to use and it just works. Simplicity is something we all can appreciate to reduce the complications and stress in our lives.
