Hello fellows,

I have some files which consists a setup program worth 11.1 gb in size.

I want to burn these files into multiple dvds. For example, 3 dvds having size of 4.7gb OR 2 dvds one can be 8.5gb in size and another one can be 4.7gb in size. Moreover, i want to burn these in continuous manner. So that during installation when dvd1 is finished, the pc will ask for next dvd in order to continue.

I tried using winrar to create the archive in 4.3gb sizes but in this case, during installation, i will have to first extract files from archives (in my hard-drive) and then can start installation, which I don't want.

I tried to create image from these files and burning to image recorder in nero express 7. But it can't create image of files more than 8.5 gb. Please suggest me ways on how to do that...

Thanks for any information in advance...
Regards Shouvik

is right to flag the tricky part: the “insert disc 2” prompt is not created by the burner, it is built into the installer. Multi‑disc installs are defined in the installer’s media metadata (e.g., MSI’s Media table) which maps files to specific discs and verifies each disc by its volume label. Without that original mapping, simply slicing files across DVDs will not make a continuous, prompt‑for‑next‑disc install work. If your setup is MSI‑based and already split into external CABs, you can usually reburn by keeping the exact file layout and disc volume labels the installer expects. If those labels or file placements change, Windows Installer will not find the next disc. See Microsoft’s notes on DiskPrompt/VolumeLabel behavior for details (Media table). Also, MSI packages must reside on disc 1 (Microsoft documentation).

A couple of practical checks and options:

  • If any single file exceeds a 4.7 GB DVD, a single‑layer disc cannot hold it. Use UDF when burning to support files >4 GB, and prefer a dual‑layer DVD for big single files (CDBurnerXP: Create Data Disc).
  • Disc spanning in burning apps only divides a collection of files across discs; it does not turn an existing single‑disc installer into a multi‑disc installer. For example, CDBurnerXP can span data across multiple discs, but when a single file is too large you must split it first (their guide shows using 7‑Zip) (Disc spanning, KB: burn extremely large files).
  • Nero’s DiscSpan can even split large files and write them over several discs, but you restore with DiscMerge before running setup; it does not provide an on‑the‑fly “insert next disc” install for arbitrary packages (Nero Burning ROM manual, DiscSpan).

Bottom line for : unless the original installer was authored for multiple discs, you will need to either (a) rebuild a spanned installer, or (b) use a dual‑layer disc or USB drive and install from a single source.

inno setup is used to create new installer...

in my case, i already have it and also i donot have the setup script that inno setup requires to compile the setup program...this setup is from diff. source and unfortunately i lost the discs...

all i need to do is to burn the files in multiple dvds so that it can be kept in continuous manner...

thanks for your rply...

usually a setup that spans multiple disks requires certain files on certain disks and in a certain format. Without knowing the exact specifics it's going to be very difficult to organize your disks. If the setup is very flexible that way, you could us a disc burner app that supports disk spanning such as, CDBurnerXP.
