By keys he means USB stick / usb key..
If it's formatted as FAT32, then it won't allow filesizes over 4GB. You didn't answer his question, how big are these files?
Do you need them as a RAW files, what format are they?
Can you shrink them down with handbrake to MP4/MKV files? Or do you want them as they are.
Also, I think you can set a split size on ShadowPlay, so might be a good idea to do that for future? Only problem with that I suppose is re-joining which is more difficult with a video file compared to a zip.
Okay, I've split one of the big files.
Do I need to use handbrake to convert to so it can be played / edited, as the file type now says .001?
Winrar or still 7zip?
