Part 1 is 26.3 M Byte
Most parts except the last are about 1G Byte
The last is less than 1G byte.

Part-0002.calibre-data is 12.4 GByte. Copying that to Linux Server HDD is not a problem (ext4). Copying it to a USB stick via LAN seems to get connection timeout at about 4.3 G Byte. Direct export to that USB stick also failed.

Because the USB stick is FAT, a file can't be more than 4G byte at the power of two, 4 GiB minus one byte, or 4 294 967 295 bytes, hence fails at 4.3 G.

Calibre 7.8 on Linux Mint 21.3 x86-64

Not sure why part2 is so much bigger unless it's the FTS database in one piece?

FAT32 is common for interchange betwen different OS.
