Usable, free ISO file editor that runs on Windows?

Question

I need a free (libre) utility for Windows that allows a person to edit an ISO file.

The goal is to be able to:

• Mount the ISO file with the ISO filesystem being readable and writeable.
• Make changes to files in the ISO filesystem as needed via the utility.
• Unmount the ISO filesystem with changes being saved to the ISO file.

How can I do this? Is there a utility, or do I need to build a toolchain?

Answer 1

there is no "free (libre) utility" that does all this.

you can use 7-zip to extract ISO images, WinCDEmu to mount an ISO image and InfraRecorder rebuild and write the ISO Image to disc.

7-Zip, Win CDEmu and Infra Recorder are free open source programs (which is pretty much as 'libre' as it gets :), prortable versions of 7-Zip and InfraRecorder are available.

Answer 2

I don't know of any free software that allows you to mount an ISO as a read/write drive. ImgBurn though is a free tool that will allow you to extract the contents of an ISO, then modify the files, then re-create the ISO.

Answer 3

A .ISO file is specifically designed to contain an image of a CD-ROM. Therefore, there is no easy way to mount one as a modifiable disk.

It may be possible to use a CD-ROM Emulator (ex. Daemon Tools) to mount an .ISO as a CD-RW, and use CD-Burning software to modify it. However, I do not know if changes would persist (it would depend on your CD-ROM Emulator).

What are you trying to do, anyways?
