When connected to a computer to load or delete files it mounts as an MTP device. Adding and removing files and folders within the standard pre-installed folders is fine but I've discovered that if I create a folder of my own and copy files into it, I cannot delete them.<br><br>Using Caja or PCManFM (on 15.10) I just get a message "libmtp error - could not delete object".<br><br>The folder and file permissions cannot be viewed from the file manager either. The panel just says "The permissions of MyFolder could not be determined".<br><br>Does anybody have any suggestions as to how to get full control over the folders and files on this device?<br><br>Thanks<br><br>Nige<br id="FontBreak"></font> </div></body> </html>
