I have the same problem need to decode ~cr to .jpeg files. I have also formatted my 64GB SDHC card and no way of decoding my original pictures. I tried CardRecovery which said free download but that's all that was free the "download". I do not have any money so cannot purchase the software or decoder software... they go to a lot of trouble telling you they have the answer to your problem and then there a catch by the time I realised I'd have to pay for software/decoder programme, I had already formatted my SD?HC card.
