Can an SD memory card, like they use in digital cameras, hold any type of data?

Are there any limits to the file extensions they support? For instance, can they be used to hold applications written in languages like C++, assuming that the program's small enough?

Okay, cool, that's what I thought. Makes sense, thanks everyone!

Yes, it is merely a data storage device for storing binary data.

Files of any type can be stored on it.

They can hold ANY form of data that a computer can recognize.

should be able to they can hold most things

yes my dear a memory card is a memory card meant for storing data

Of course they can fit anything. I use one for my psp, and i hold full programs sometimes, just depends on the size of them. i can store full games with my 3 gig SD. good luck.

When installed in your computer is becomes just another "DRIVE".
