It looks like file date/time is the key to getting Google Drive to update the file.

I created a TrueCrypt volume inside the Google drive. As soon as I did that, Google copied the file up to the cloud. From there any changes I made to the volume after mounting it in TrueCrypt did not trigger an update.

However, as soon as I updated the date/time stamp on the TureCrypt file Google saw the change and updated the file.

Better, but I'm still looking for a way to encrypt individual files to/from a Google Drive.


Note: To update the date/time on the file I used the old batch file command:

copy /B filename +,,
