Make Use of Gmail Space

I found a piece of software to make better use of Gmail's 2.5G+ space other than just storing your email. This is the link ->

It basically creates a virtual hard drive in My Computer and the user can make some basic file operation such as copy and paste in this drive, and all files moved to this virtual drive are actually stored in the Gmail server of your account. In the Gmail webmail page, the files exist in the form of email of single file attachments. So, it's an easier way to store files in your Gmail cyberspace than writing every email with those file attachments in the webmail interface. But be sure to use it carefully 'cause it may violate Google's terms of use of not using third party software to interact with the Gmail, that said, if too many files are uploaded and downloaded at the same time, the Gmail account may experience a temporary lockdown, or the Gmail site will be simply inaccessible to your computer with the prompt of "server error". The obvious downside of this application is that your internet uploading & downloading bandwidth determines the copying and pasting speed and that large files or files with long names are not able to be uploaded due to Gmail's policy on email attachment.
