Example? ES File Explorer.
I'm sure I'm being extremely dense! I have a Samsung Galaxy S2, and it has some videos stored in the phone. I recently put in a microSD card, hoping to be able to shift the vidjs and also some other stuff onto the card within the phone. So far I have only succeeded in moving the contacts file onto the SD card. There isn't any hardware problem, it is simply that I cannot ever get up a menu which offers me the option of exporting to the SD card (except for the contacts).
I hope somebody can explain what I have to do! (I can shift data out of the phone with wifi, bluetooth, and the USB cable - but how do I move data within the phone?)
I don't know if this is an Android or a Samsung query, but since it is so very basic I'm sure that doesn't matter.
