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?

@matt wilkie do you have a Winrar registered version? – avirk Jun 27 '12 at 17:44
No @avirk, I don't. I generally use 7zip. Why, does registered winrar edit ISOs? – matt wilkie Jun 27 '12 at 18:02

It's shopping for a product recommendation. That goes either off topic or not constructive @mat – random Jun 29 '12 at 16:09
@random: I'm not trying to be difficult, but I must admit I don't understand. The FAQ says "shopping or buying", but this cannot apply to freeware. Polling isn't mentioned, but even if it was the dictionary makes it almost synonymous with voting, and certainly there was no voting requested here or an opinion poll. How is asking for recommendation same as polling? And remarking that SU, by its vote system, is nothing else than an opinion poll system. – harrymc Jun 30 '12 at 15:23

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.

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.

I tried ImgBurn today. It's closed-source and adware-ridden. I've uninstalled it. – bukzor Mar 2 '14 at 3:29
Yes, when I originally posted this, although it was closed source, it wasn't full of adverts. It has since gained more and more adverts so I'm also looking for an alternative. – pipTheGeek Mar 4 '14 at 9:44
I've used InfraRecorder and am quite happy. It's open source and has all the features I want. – bukzor Mar 4 '14 at 22:21
Poweriso + MagicISO + UltraISO + WinISO (filesize limit); ISOpen (FREE); SecureCD creator (FREE); ISO master + gBurner (trial period); – tazo todua Mar 25 '14 at 13:50

UltraISO : On June 2009, PC User magazine Australia offered v9 full version to its readers.
Here are the registration details.

Name: PC User readers  
Serial: 4BF9-8D1E-1786-30A8

Do take note that this registration details will NOT work on the trial installer that is downloadable from UltraISO's website, but the original version can still be found by googling for uiso93pes.exe.

TotalMounter is advertised as a free ISO editor, but I have no experience with it.

Folder2Iso does what it is named for, and can be used instead of an ISO editor.

is there a citation for the PC User magazine offering? ...just thinking it would be a good idea to back the claim up, making it clear this isn't warez or similar. – matt wilkie Jun 27 '12 at 17:50
This UltraISO freebie is plastered all over the Internet, but impossible to find out its source, since PC User was apparently sold. One source is here. – harrymc Jun 27 '12 at 21:38
Re: Folder2Iso; the Folder2Iso page itself says clearly About : Folder2Iso just creates an iso from any kind of folder (with the subfolders). Nothing about editing. Re: TotalMounter; Cool. A virtual CDVD-RW software has been elusive for a long time. My only concern is with the terrible writing on the page. It looks like a non-native English-speaker wrote it, but there is no indication of the company being foreign. Oh, also, it seems to be free due to built-in ads. – Synetech Jun 28 '12 at 6:05
@Synetech: Folder2Iso: I just wanted to mention it as last possibility, when having no other solution, to edit the folder and then create the ISO. Not the best, but at least free. – harrymc Jun 29 '12 at 14:03

New answer:

There's practically no all-in-one utility to achieve this on windows, although some alternatives for Linux exist. Your best bet is to extract the files, change them and them generate a new ISO, or work with 7Zip.

Old but updated answer:

You clearly state that you want to mount and then edit your image file. So:

  • For a FOSS/Libre utility, try ISO Master or AcetoneISO.
  • I'd suggest using a freeware or even shareware utility, like 7-Zip, MagicISO etc.

An old question but I recently stirred the pot as I'm looking for updated answers. :) The feature set of AcetoneISO looks rich, but is linux only and this Q is specifically for Windows. 7zip has already been mentioned. MagicISO is new to this thread, mentions editing as a feature, but while inexpensive is not free. – matt wilkie Jun 29 '12 at 16:07
Is AcetoneIso a free iso editor? maybe not.. – tazo todua Mar 26 '14 at 22:21
@Solutioner: It's FOSS although it's not an editor indeed. Best and probably only free alternative for windows is 7Zip. ISO Master is free for linux and shareware for Windows but you have to find it on download sites such as softpedia. So, either one uses a shareware utility (lots of them: WinISO, MagicISO, PowerISO) or extracts the iso, changes the files, and creates a new one. No easy and free all-in-one solution exists (let alone a portable one...). – Astyanax Mar 29 '14 at 13:01
