back again guys. is it ok to ask something else from inside this post? if so, can someone guide me with this please?
thanks to the help already received, i have got es file explorer on the OUYA and working. i put a couple of game downloads into a folder on an sd card inside a card reader. i can see those games. my thinking was then wrong, i guess. i was given the option of installing those games and i thought they would be installed where they should be, on the OUYA. that appears to not be the case. i have no idea where they went, but going to 'PLAY' showed me nothing (with the sd card inserted or not inserted). all i was directed to do was go to the 'DISCOVER' option to get some games.

so, am i right in assuming the games were not installed on the OUYA? if they were, where are they? i uninstalled them, thinking they had somehow been installed on the sd card? wrong thinking, perhaps? how do i get to install the games from the sd card on to the OUYA so they are seen there and can be played? i cant see any option of copying them from the sd card individually or together in the folder to somewhere on the OUYA.

next question is, how doyou delete things from the OUYA? remembering that i had 2 versions of es file explorer that i downloaded on to the OUYA which didn't work, i cant se any option other than to install or uninstall. i would like to get rid of them completely, keeping on the OUYA just what i need to keep. any way of doing that?

many tnx again guys. if i have done wrong by asking further in the same post, tell me what to do and i'll start a new post
