I was finding difficult to share huge mb file to my colleague so this problem was solved by drop box, where I just have to share the files in drop box and my colleague were able to see the files which saved a lot of time.
The best part is that drop box provides a huge space which helps me to save a space in my laptops and other hard disk as it provides 48 gb free, which I think more sufficient and this software is free of cost. I have seen my friends where they buy tabs just to save the files in it which I think just a waste of money instead drop box can help us and replace it.
As one have have to login so it is very difficult that data will be leaked and I have never faced any issues where the data gets hanged or something.
Really one can get reliable and be tension free!
