Hi Alphie,
Yes, unfortunately, there is currently an issue in generating WACZ files over 4GB. I am looking at ways to fix this. There are currently several options:
- Split into smaller files by pages, if possible, and then download individual WACZ files. We can help you combine the WACZ files into one.
- Download the files as WARC/1.1 and then convert to WACZ, however, that will not include the page info.
I’ll see about improving this in the next version of the extension. In the meantime, if you downloaded the individual parts and need help combining, let us know and can help with that.
Sorry for the inconvenience!
