Convert multiple NRG files to ISO files

I have multiple nrg files which I would like to convert to iso or just extract the files to a directory (similar to what winrar does for iso files)
I would like to that that in one action (i.e. not per nrg file) preferably from the shell.

I need to ask.. Why would you ever need to convert NRG to ISO. There are always programs to handle opening them.

If you just want to see the NRG image, then why not use Daemon Tools.

The program allows you to mount any sort of image and lets you see it as if it was a CD then you can just copy the content, just like copying stuff of a CD/DVD

Virtual Image drives are the way forward. If you desperately need to convert, then whip up a script so you can do many at a time, otherwise there is hardly anything out there with support of a lot of NRG to ISO. It’s hardly ever used, that’s why I’m suggesting virtual drives.

Hope it helps

The ONLY program that handles NRG files is Nero.  So unless you run Nero and handle each NRG file individually, you will not get these files into any other format.  NRG is a proprietary format that NERO invented, and no one else has tried to copy it, because, after all, it is only a list of files and directories, packed into a specially encoded database that only nero can intrepret, so why should anyone else bother?

So, because Nero is the only one to handle the format, and it allows only manual handling of these files, the only thing you can do is handle the files one by one -- sorry.

Not sure if the following addresses your "one action" requirement, but take a look -

I got it by googling "nrg to iso".

Free Tool: ZipGrep

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

One of a set of tools we're offering as a way to say thank you for being a part of the community.

Get a copy of isobuster, it can read nrg files and it extracts them into iso's. It names them tao, but that is the same as iso and all you need to do is rename it to iso after that.

"... I would like to that that in one action (i.e. not per nrg file) preferably from the shell ..." ==>  Not aware of any utilities to do it as a batch.   NRGtoISO (as already linked to above) works fine --> I've used it to convert a few downloads;  but it's a simply little Windows utility that you have to "point" to the source and destination file.   If you have dozens of files to convert, it will do the trick easily;  if you have hundreds it would be a bit of a pain;  if you have thousands, you need something else !!
Hmm ... if that utility works with the command line "nrg2iso sourcefile destfile", we could whip up a script to run it on multiple files one by one.
Gary CaseRetiredCommented:
... yes, you could even pipe a "DIR *.nrg" output to a file, and then cycle through it line by line.

BUT ... it doesn't work as a command line utility  (I was fairly sure I tried that some time ago when I used it;  but just to be sure I just tried it again).
Maybe because iso is the standard and he has to distribute the files to customers?
The thing is, Daemon Tools, or Alcohol 120 or any of those, just emulates as if a disk has been placed into a drive. Therefore you can distribute Daemon Tools to all of your customers. They then mount the nrg, or any image file, go to My Computer and its done. The disk is there! And just copy stuff right off of that virtual disk. Rather than converting to ISO then trying to unpack it with WinRar. That’s silly and is a longer process, in my books! :P

The thing is that Winrar can extract files from ISO files just as if they where zipped files.
So I can extract many ISO images into files on my HD at once.

Having 10 nrg images what Marc5000 said takes longer to mount each image.

I found UltraIso which does the job.

Oh UltraIso, basically the same as MagicISO but hey. I was going to recomend that, but i didnt know if it could handle lots of NRGs
Oh well!

So who gets the points, or is this a dud?

Except MagicISO doesn't seem to be able to convert multiple Images at once and UltraIso does.
