Google Drive is an online file storage application similar to Dropbox, but with a twist.
In addition to standard file storage Google Drive offers several additional features including file revision history, built in compatibility with Google Docs, and a powerful search tool to navigate your files.
Google Drive is free to use and comes with 5GB of storage. Additional storage is available for a yearly fee.
