I've just noticed that a file I downloaded and can't copy onto my MicroSD card is not due to lack of space on the card, but due to the fact the file is a bit larger than 4GB.

I don't want to change the filesystem on the card to extFAT because I doubt that all of my devices including cameras will work with that fs.

Is there a tool designed to chunk files into 4 gig pieces to work around this very problem?
