Alex, I appreciate your help and information very much.

Further developments: I sussessfully burned that iso image with Nero 7 on
the rig with 4GBs but then I decided out of curiosity to repeat it with the
script. The burning failed. It seems I got a completely prestine, empty disk.

In the task amnager I observer memory usage mounting slightly over 2Gbs but
not as much as 2.65 Gbs that could be expected from the source iso file. I
suspect there is another issue involved. Perhaps WMI cannot handle such big
files no matter what. Nero 7 employed buffering which was evident from the
fact that the memory usage never exceeded 800 Mbs as was apparent from a
progress bar at the bottom. on this superfast quad it took about 3 min.

Yeah; this is a classic example of why pipelining is so useful; any tool that needs to manipulate something in a chunk is eventually going to run into trouble with large enough chunks.

I am wondering if you have any experience in handling iso files via any .NET
classes or even scripts. I do have Winimage.exe installed and it opened the
disk file momentarily and displayed the tree directory but I want to examine
other options. I've been looking for a chance to get a handle on iso files
one way or another.


For open source .NET software, the place to look is always Codeplex (http://www.codeplex.com). I'm having trouble with their site search this morning, but googling gave me a C# ISO image creator:

There is also a .NET 2.0 burning library here:

Doom9 (http://www.doom9.net) has a lot of links and background information, but most of it is focused on DVD video burning. It's still a useful place to find various tools and some source code.

Freshmeat has several specific tools for ISO handling, usually in both Windows and Linux versions, with source code. These are most often written as


Perhjaps you know of a web site where the complete file format is described
in detail, metadata including.

Many thanks.

I think you're fine. The right way to do this reliably for virtually anyone
would be to find a unique string in the ID, then use that as a comparison
check before burning, but in reality I don't see it being a problem.
Generally static CD drives are the first items on the list and won't move it
appears.

Haven't used it enough to have a strong opinion, yet. ;) My first scripting
experiences in the early 90's were on a then-ancient PDP and some
Sparcstations, but I've always worked in the Windows world - and for
everyday use, I've felt Windows desktop systems are clearly superior since
the introduction of XP. I installed it as a virtual machine for some testing
primarily.

There is no such thing as "too much RAM". ;)
