Here is a very useful little software that you can find lots of use for. Once installed on your computer, it exists as a little icon that opens like a normal folder. So you can think of it as a folder which resides both on your computer and in the cyberspace "cloud". Here are two major uses of Dropbox:
You can install Dropbox on all your computing gadgets: laptop, smartphone, iPad or Android tablet. Once installed, you can place any file in Dropbox. You can access this file from any one of your computing devices. Each time a file in Dropbox is updated from anywhere, it is also synchronized to all your other devices. The file actually resides both in the cyberspace cloud as well as on each of your devices that has Dropbox.
I find it particularly useful for sharing large files, such as a video recording or a whole bunch of photos. All you have to do is to put the file in the Public folder of your Dropbox. Then go to that file in Dropbox and right-click to get the link. Email this link to anyone. This will save you from emailing huge files to your friends, and they from having to wait for the download to complete. For handling many files, I find it useful to zip them up so that you only need to send one link.
