In the meantime I have got my Nexus 7 tablet working using FTP. I use NetDrive on the PC to mount the tablet as a drive letter and FIle Expert on the tablet acting as an FTP server. Then use Calibre Connect/Share Connect to Folder and connect to "Android/data/com.amazon.kindle/files" on the tablet drive letter and everything works fine. A little convoluted perhaps but it works.
