My online file sharing and storage program of choice is Dropbox. It is a free program and when you register you get a reasonable amount of space for free. If you want more you have to pay for it.
If you use Dropbox to store your files you can work on them directly in Dropbox, just open your work, make your changes and click the save button.
Great if multiple users need to use the one file and this is especially handy for those really large files if you are short on space on your work servers. All you need to do is invite the user to the folder or file you want to share with them.
You can update files without having to save them off and then re upload them. If you register, don’t forget to download Dropbox to your computer, you won’t have to sign in via the web again to access your files.
