One of the easiest ways to make some extra cash online is to upload and share files with other users of the internet.
This is available through some websites which offer you free space to upload your files and let others download it, these websites pay you every time a certain number of people download any of your files.
We all are familiar with some of these websites like Rapidshare and Upload, but not all of these websites pay you for using them. One of the best websites which pay you for sharing files is "DepositFiles".
All you have to do is to create an account and upload some files, then let others download these files through your links in social networks like Facebook or bookmarking services like twitter. You can also post your links on forms and blogs to let more and more people download your shared files so you can earn more money out of these downloads.
Finally, you have to know that these sharing websites allow you to upgrade your account from free to premium, which gives you more features and allow you to earn more out of your sharing activity.
