Size of the WinRT Roaming Folder

Revision 2
Hello!

I need your help guys and girls :-).
I´m messing around with Win RT to make some apps....well, I like to use the roaming folder to store some textfiles. So, I´ve read that it (the roaming folder) can only be 100kb at all?! this is not much, and some textfiles will be bigger then that? what should I do, or I´m missinformed?

thanks a lot!! :)
greetings
