I had produced an archive that I could locally extract all files, but my 4.5GB OBSERVATION,csv file was at an invalid offset within the archive (observation was the second largest file to MEASUREMENT.csv at 24.0GB within the archive). I tried reinstalling zipR and possibly also tested compression using Windows native zip folders.
The solution that eventually worked for me was to use 7zip from the command-line
7z a MySiteArchive.zip -tzip -mmt -r0 *.csv DATAFILES/*.csv
testing of the archives was performed with
python -m zipfile -t MySiteArchive.zip7z t MySiteArchive.zip
and -
7z l -slt MySiteArchive.zip
unfortunately, I did not record what R version or zipR library version I was using at the time.
