A nifty idea - set up your Gmail account so that it lets you use Gmail as a place to store things: files, games, music, images, programs, whatever you want to store:
GMail Drive creates a virtual filesystem on top of your Google GMail account and enables you to save and retrieve files stored on your GMail account directly from inside Windows Explorer. GMail Drive literally adds a new drive to your computer under the My Computer folder, where you can create new folders, copy and drag'n'drop files to.
Your Gmail account offers a gigabyte of space, so plenty of room.
