Argh! I really have to start searching GitHub before entering my "coding mode". Thanks for the script!

Is there a way to set a sub folder for syncing? Since I use the full access instead of App folder. Thanks.

I found that this script would crash when it attempted to sync files in the Inbox directory, since the script does not appear to have write permissions for this directory. Here is an attempt to mitigate this problem by preventing the script from writing to Inbox. It is a quick solution, which stops the script crashing, and allows it to sync all files except the Inbox directory.
