Tried to get an answer in the Google forum but no reply:- https://support.google.com/drive/forum/AAAAOxCWsToTxRHTSl-92A/?hl=en I want to use the 100GB Google Drive for $24 per annum to store some 88GB of my music files; slowly growing but will be several years before it exceeds 100GB. The files are on three Andriod devices (one phone and two tablets, so 88GB on each), held on the external micro SD 128GB cards in each device. I sync them by keeping a careful watch on the state of each card and manually sync as required. It would be good if I could just amend one card, on the device I have with me, and let Google Drive auto sync all, as and when they are in wifi range. I am only talking about one main folder on each card i.e. card root > Music and its sub folders. Will Google Drive sync only to a specified folderm in this case Music? Any advice please?
