How do I make a multi-volume archive?
I need to install a single huge file (maybe even bigger than 2GB). How do I make it into four 640-MB (CD size) chunks?


1. possibility:
pack the installer to a splitted self-extracting archive with winzip, winrar or similar.
2. possibility:
don't pack it into an installer, but let the installer copy it from the cd and kit/install it on the hd.


First of all it might be good to get confirmation, that installer process may be detached from CD (some kind of fork). I launched my package from network drive and then Disconnected it, as a result - "Error decompressing data! Corrupted installer?" Or Installer must be copied to tmp folder first like they do it on uninstall, I can see just created A~NSISu_.exe in Local Settings/Temp).


What about placing a specific file on each CD so the installer can differentiate between the CDs.

Then you start with CD 1 where the Autostart calls a batch (or something similiar) which copies the installer to a temp Directory and starts installing from CD1, after the files from CD1 you prompt the user to change CD - on which he can react with ok or cancel if the input is ok you check for the specific file on the CD and if its correct, you proceed -in the End you can close your installer and delete the installer.exe from the temp folder...

have i reinvented the wheel or was this what you need?
