There are three disadvantages of online file sharing and storage. First, online file storage websites are like any other business, existing to make a profit. If the business is no longer profitable, it can dissolve or declare bankruptcy. There's no guarantee that the business will notify customers. Second, Online storage sites pop up every day. While most of these sites are legitimate, you can’t be certain the wrong person won’t access your data. The bottom line: people running the website will be able to view your data. It’s make that you don’t have a piracy. Third, If you need an Internet storage site that lets you upload unlimited gigabytes of data, you’ll pay for it. There are free services available, but these typically limit the number of gigabytes uploaded. Also, beware of services that don't charge for uploading data, but charge for downloads
