Hi, Val Monaghan
I just wanted to add to this. As MsJenniferS mentioned the options that were given are what you can do.
The Google Docs file can only live in the Cloud, meaning it can only live in Google Drive. There is no way to save it to your local computer hard drive.
You only have the ability to download the file as a file other than a Google Docs file. You can select any of the options available on the Download menu. It works this way by design.
I hope this helps,
Ben Liebrand
