GSpace

GSpace Firefox extension allows you to use your Gmail Space (2.8 GB and growing) for file storage. It acts as an online drive, so you can upload files from your hard drive and access them from every Internet capable system. The interface will make your Gmail account look like a FTP host.

After the installation, you'll get an option called "Gspace" in your "Tools" menu, which opens the GSpace window.

It's great for storing/sharing files with your friends. Also very good to backup photos and music files (as you can view/listen to them from Gspace). It can turn your gmail account into online storage tool stuffed with handy features.

Gspace has four different operational modes;

1. File Transfer Mode: download/upload
2. Player Mode: listen to your stored music files using gspace’s built-in media player
3. Photo Mode: view and browse through pictures and albums stored on gspace
4. Gmail Drive: manage Gdrive files
