Is it possible to copy protected files from a MicroSD?

Hello,

I have a Nokia 6233 which came with a pityfull 64MB memory card with a few pre-installed things on like themes, games and a few applications all in an 'Extras' folder.

I have just bought a new 1GB MicroSD and have been having a nightmare trying to copy this 'Extras' folder as it seems to be protected.

I have tried making a Windows backup of the old card and then restoring it to the new one which at first seems to work, within windows the files appear to be in the correct place on the new card. When I put the card into the phone again I can see the 'Extras' folder and it's sub-folders but when I try to open a game or App it just says 'Invalid File'.

Is there anyway I can do this as I don't want to loose the games and apps.

Thanks for your help.
