large RAW files don't open after in camera formatting (solved!!)

[COCO]

It had been a long, hot day of filming ...
Accidentally formatted CF-cards in camera (5DIII). Shots beyond 4,29 GB don't open, can't be converted to DNGs, some are zipped. This must have happened to someone before - hopefully there is a solution. Haven't tried Treasured or FCS Maintenance yet. Would dare to add mdat data and moov atom on my own, if there was a manual.
Grateful, not dead yet.

Update: Found a thread mentioning the cocenate - method. That fixed my problem. Thx

COCO, which its formatting? Directly from the camera?
You may have some scruffy block ... try to use a tool for low-level formatting, and then use the SDFormatter. If not, try the Paragon alignment.
Probably the files were corrupted ... the most you'll be able to do is extract some DNG's... an important tip is to not turn off the camera after recording a sequence, because it may still be processing what will corrupt the entire sequence. The ideial is to do nothing, and wait maybe 5 seconds only.
ps: try exFAT, too.
