Thanks for your very detailed explanations majorassface.
I hide the ROM files into Reso Explorer now.
But what remains strange is that Windows XP Explorer via ActiveSync also show me all these files, when it was not the case one month before...
I will also set the cache for Opera on the Internal Storage. By the way, I do not use Opera very often so all these files are not its fault.
And I wonder why do some games add xxx.2bp files into Windows folder as well?!?
It is the case with SolitaireCity and Chainz, Dynomite, Cubis for example. Resco Explorer can display these very small pictures...
Grrrr!
