I’m totally stoked about this Firefox plugin called Gspace because I’ve been looking for something like it for a while. Gmail accounts come with massive storage space – just over 2.9GB as of today. This plugin lets you use that space for file storage as if it were an FTP server. Free offsite backups anyone?

When selected (Tools -> Gspace, or via the icon on the bottom right of the Firefox window) the plugin opens a new tab that looks like an FTP client. When you use the interface to transfer a file to your storage space, behind the scenes the plugin sends a cryptic email to your account with the file attached. While I haven’t gotten this far yet, I’m thinking it should be relatively painless to create a filter that moves these cryptic emails into the All Mail folder so they don’t clutter up your inbox. Check it out and let me know what you think.

Update:  even better than GSpace, GMail Drive is a standalone Windows application that mounts your Gmail space as a drive letter.  Drag and drop files in Windows Explorer to store and retrieve them!

NOTE: the maximum file size for both applications is 20MB as that is the size limit GMail enforces on attachments.
