I do not use Google Docs as my primary storage, so basically I am even satisfied with the free 1 GB storage. But, after getting news from various sources, I logged in to my Docs account with curiosity to see if I have been also graced to have some more thicker storage on the free Docs platform. But it was sad. I could not find any changes in my account, neither in space consumed and left section.
With a bit of frustration, I searched for why and how Google is expanding the storage for free accounts. I found this and tried.
I uploaded a small file to my account and checked the storage details again. Now, what I saw was not so much useful for me, but I was happy to see this. My space increased from 1GB to 5GB instantly.
This expansion is due to the newly launched Google Drive, which is similar to services like SkyDrive and Dropbox.
Now afterwards, all new signups will get initial free space of 5 GB. But existing account holders may require to use this trick for the expansion.
Don't waste much of you time in reading this post. I am over. Try yourself this right now if you are running out of space. But don't forget to notify me if it (not) worked.
