Google Drive and OneDrive do not use the file name as the unique identifier of a file but, rather, some unique id generated when the file is created. Therefore it is not possible to correctly update the file in the online store by simply deleting the existing file and uploading a new one with the same name as the new file will have a different id. Another reason relates to the need not to lose or change the original RK for encryption of the file content. For this reason NSCM offers a separate option for updating the file, by clicking “Update” in the file context menu. A new window will be opened:
Click button “Browse” to select the new version of the file and then click “Update”.
