Uploading multiple data files to OneDrive App (android) automatically adds duplicate files into existing folders of data.
When uploading data to OneDrive Android App, the app default setting is to automatically add files into existing data folders. it does not check these data already exist (filename nor fn+size) in that folder and it automatically adds duplicate data into these folders. it does this by appending 2 to the filename. It would be useful if the facility to replace existing data, to copy all data (+ therefore duplicate it), or to skip transfers (where these data files already exist in that folder) could be presented to users. Furthermore the help does not mention this at all, nor gives you "settings" in which users can modify this default setting.
