I almost never endorse products in this blog. Dropbox is an exception. This service provides free online storage of your data- up to 2 gb initially. You can access your Dropbox from anyplace there is the Internet- desktop, laptop, tablet, phone, etc. For example, the other day I left my flashdrive with all my class PowerPoints at home. However, I just logged into Dropbox from the classroom computer and downloaded the files. Another time I realized just before class that I wanted to do an activity which was not on my flashdrive; within a few seconds, I had logged into Dropbox from the class computer and downloaded that activity. Likewise, since I have Drop box downloaded on my laptop and notebook, I can alway make sure that the most current version of any file is available. I do not have to worry about updating or moving files from one machine to another. I always work from my Dropbox files so they synch up. In addition, I can easily share a file or folders with others. If you get others to join, you get additional memory; if you share files, you get more memory. For example, if you install Dropbox from the link below, I receive additional storage and you receive additional storage.
