Storage matters & STICK KU1

[QuasarSL]

Hi,

My STICK has a Mini SD card. Which I was going to replace.
I realise that Mini SD is being replaced by micro SD.
However you can stll get Mini SD cards. But in larger sizes than the supplied (if I remember correctly) 256mb.

My questions are:

Is STICK KU1 able to use the larger Mini SD cards say 1Gb or above?

Is STICK KU1 able to use all of that storage space?

Does the card need formatting?

Thanks,

Keith
