Dropbox is a great application. You can download the desktop version on your PC and also you can download the app for Android and IOS devices. Whenever we go for travelling, business work, away from home we carry our data in pen drives hard drive and also we have a chance of losing the data for such cases dropbox is the best. Basically you need to save your data in Dropbox and you can view your data from anywhere in the world buy just logging into dropbox from the place you are and you can view your files and data from that place only while you had saved your data at your home somewhere else in your PC. This makes it handy for the user to view his or her data anytime without carrying pen drives and hard drives. Also it keeps your data safe. I personally use this application and having a great experience till date. Whenever I go to some place and I want to view my data I just simply open Dropbox in my Android and easily access my files that I want to . You just need to save your data to Dropbox from your PC and the work is done. I recommend to download this application both in your PC and Android or iOS devices. Thank you all
