Is there an app that can transfer files wirelessly for a ds

A psp has an app that can transfer things wirelessly between a psp and a computer.
Does ds have any apps like that? Cause i dont have an sd card reader on my laptop
and my desktop is in the basement and is to far. and my usb adapter, for some reason only works with
one of my micro sd and ironically, it doesnt work for the one it came with in the r4 but another
micro sd card my other r4 came with.

There is, but it kinda sucks. You're better off finding a micro sd to usb adapter, which should have come with your card.

Lol explained it in my paragraph that my usb will only work for my 1 gb but not my 2gb
(And the 2 gb came with it.)
And the app cant be that crappy how long does it take to transfer 128 mb?

I suggest getting a new usb adaptor if this is the case.I don't think there is an app for transfering ds to pc...well there might but I doubt it would be any good.128mb...that would take maybe...an hour on the ds :(What brand is the reader?

I suspect the microsd that doesnt work is an SDHC and the reader does not support SDHC.

They are both made by kingston. other than the size, it they should be the same.
