Using cloud storage is very convenient when you are using more than 1 computer. Google Drive or Dropbox provide that facility where you can store your files. You can access and update the files on the cloud storage from any computer. But it’s sad to know that Google Drive and Dropbox have stopped supporting computers running on Windows XP. You have to upgrade to Windows 7 in order to avail of the cloud storage facility.
Windows XP is very outdated and people shouldn't be using them. Even in Virtualbox I run Windows 7, not XP and that's with limited resources available to Windows 7, and it all runs smoothly.
