Windows 7: How to edit existing or create new iso bigger than 4gb

How to edit existing or create new iso bigger than 4gb

I have created a All-in-one install source with all 32bit and 64 bit editions of Windows 7. I then edited each install index (11 in total, Starter, Home Basic, Home Premium, Professional, Enterprise, Ultimate 32bit and 64bit except Starter) with updates and drivers using DISM. The resulting install.wim file is now over 4GB. What I want to do is edit an existing iso file delete the original install.wim and put mine in its place but my usual way to edit bootable iso's (magiciso) seems to not allow files over 4GB in size. If anyone knows how to edit an iso and put files bigger than 4GB I would be very appreciative. Or if I have to create a new iso that is fine too. I have it on a USB working fine but I want to have all my work backed up in a bootable iso.

Are you working on a 64 bit machine with NTFS file structure

I havent checked but im guessing that the app your trying to do it with is 32 bit and i think you would need to use a native 64bit program so it can recognise files over 4GB

What would 32bit application have to do with 4GB size of file? Plenty of 32bit applications do not have 4GB filesize limitations. You are confusing the amount of RAM on a 32Bit OS limit. Just for fun I just checked and had a 4.4GB iso file on a NTFS filesystem I used the same 32bit app (magiciso) and burned just the file to a disc. No problems so the issue is still a mystery to me. So no one has bothered to do what I did and update all the editions of 7 with drivers and updates? Thanks for your response either way, Pauly.

You need to make a list of files you need at the start of the image and call oscdimg with the -yo option. Its all in the WAIK documentation.
