Individual documents can be downloaded here:
https://www.archives.gov/research/jfk/2017-release
They are organized by document number, so are pretty much useless without a reference.
Here are the links to the zip file parts. I haven't downloaded all the files, but it looks like the total size is over 20GB.
WARNING: It is not possible to open the archive until all 11 files are completely downloaded!
Completely download all 11 files to the same directory then open jfk.zip to unzip all.
Download times may be significant due to the large size.
