I'm trying to transfer the Lumberyard's user guide into my Kindle Paperwhite. Unfortunately, this user guide is too large for my Kindle: 2680 pages - About 90MB.
But how ridiculous, Each of the split files (XXX_Part1.pdf, XXX_Part2.pdf,...) has size about 80MB (almost same as the original PDF - 90MB),
80MB - Each!!!
Even the first file (XXX_Part1.pdf) only has 2 pages, but the size is still ~80MB.
This is clearly unacceptable, how can I fix this? How can I create smaller split files?
