My husband tells me there is a machine that would rewind the APS film back into the canister. Unless you can access one of those, he says you'll need to destroy the cartridge to extract the processed film, then store it as you would regular negatives.
Why not simply contact a reasonably local film developer to arrange for a cd copy to be made? You'd have the cd copy and your film would be re-rolled into the cartridge. Kodak, for example... The film is still available; I assume processing is also.
