When downloading Ubuntu(Desktop version), for example Ubuntu 16.10 (Yakkety Yak) Netboot.
After choosing arhitecture for example (i386) download directory opens and there is list of files:
Index of /ubuntu/dists/yakkety-updates/main/installer-i386/current/images/netboot
- boot.img.gz
- ldlinux.c32
- mini.iso
- netboot.tar.gz
- pxelinux.0
- pxelinux.cfg/
- ubuntu-installer/

Where can I find explanation what is the meaning of those files ad which one is correct for me ?
