One way “syncing” to Google Drive
Sometimes you only want to upload or download your files to or from Google and not do a full sync. The main reason for doing this is backups.
Syncdocs can easily do this. In the ‘Preferences’ menu look at the options in “Customized Sync Control”.
For example, if you only want to upload files to Google, then un-check “Download Google files to this PC”.
For more info on these options, see the Google Drive Backup guide
