Using ES File Manger I can sweep all pictures/video files onto a micro SD card. It would be nice if I could A: test SD Card installed and if so B: save directly to either Photo or Video directory. Obviously this either needs an alteration to camera setup/config file OR a cron to run (LINUX like). How would I go about achieving this? Doing this would go someway to preventing FULL SD cards!

PS I have still not solved problem of accessing external_SD card using USB connection from Linux (UBUNTU) Laptop - tried Filezilla and PCmanFM, the latter actual shows and icon for external SD card - but files and folders content are from internal SD Card.
