[@Peter E] Thank you for pointing out the misleading of “disk-free” statement. GDocsDrive itself takes only about 3MB disk space, and the temp files generated when editing GDrive files with local apps will be deleted automatically. Comparing to the heavy Google Drive, which can cost tens of Gigabytes of your hard disk, GDocsDrive only takes several Megabytes. It is almost “disk-free”. Whatever, the “disk-free” statement is technically wrong and misleading, we will try to find another alternative description.
