ISO disk contains more than just a file, it also contains all the hidden data that you are never aware of including any file structures, a bit like when you add a file to the hard drive, all you see is the file, BUT, behind that file are many hidden entries like in the registry for installed programs, metadata etc, an ISO contains an exact image of all this data as well as the file
Thanks 8210 guy for explaining this to me with your best efforts.
THere are 2 cases:
1) when you directly burn the CD with any data file
2) you first create the image file of the data and then burn the image file to the CD
Is there any difference between these two cases in terms of internal file structure that you explained above so that image file has file structure (hidden data) + data file and directly burning only has data?
Also one thing, I just want to know if there is any other better forum for these type of queries because I am observing that only you are responding to my posts/queries and no one else is bothered about these.

A lot of here on the forums will assume that you have done your basic research into the areas that interest you. As you know using a search engine effectively is a skill that can be an enormous help in finding out information, and obtaining different views.Also one thing, I just want to know if there is any other better forum for these type of queries because I am observing that only you are responding to my posts/queries and no one else is bothered about these.
For example with your questions on .iso file formats, we assume that you will have started with reading up on various articles like for example:
http://software.iver...sofISOFiles.htm
Having obtained a brief overview from the above and similar articles, its a good idea to then research personally the individual areas on which you seek clarification, also using your favourite search engine(s)
Many members of the forum (who like yourself have expertise in a particular area) will respond to a specific question if they feel that the questioner has completed all reasonable individual personal research and reading of the published material but despite their best efforts is continuing to have issues with a particular point.

Another thing to remember is that there is not always a 100% conclusive answer, many times variations in a users requirements can alter the answer, so sometimes you have to take a general understanding as an answer as opposed to more specific one, thirst for knowledge is great, but there are times when knowing specific things has no real benefit to the average user, not unless they are going into that area as a profession, in which case those who would employ them would train them so more specific knowledge can be gained, but the average person on a web forum would not need to know anything truly specific generally speaking, they just know what they need too so they can achieve the end goal.
As too your query here, I believe I already explained as best I can above there:-
So in simple terms if you want to just save files from you're PC to a disk, then simply burn it as a data disk, if you wish to increase how much data you can add, you can manually compress the files using tools such as WinZip, WinRAR or 7-zip, and burn the compressed file too disk.an ISO disk contains more than just a file, it also contains all the hidden data that you are never aware of including any file structures, a bit like when you add a file to the hard drive, all you see is the file, BUT, behind that file are many hidden entries like in the registry for installed programs, metadata etc, an ISO contains an exact image of all this data as well as the file
But an ISO disk is unlikely to be required by the average person as best I can see it, my limited understanding is by the time you'd need to burn an ISO disk from you're own files, you would then know what and why it was needed, sorry if this is too generalised for you, but it's my conclusion from what I can see so far, hope it helps.

Tahara,
this you have just copy pasted from other urls. ok, can you tell me one thing: when you say " iso is a byte-for-byte copy of the low-level data actually stored on a disk."what do you mean by byte for byte copy here?
Also, what is the difference in this if I copy instead of making image file?
Have you read the whole thread?
Great detective work!
Another explanation of an iso image could just have easily come from any number of sources including http://en.wikipedia.org/wiki/ISO_image
An explanation of a byte (a small collection of bits) can also be found at wiki or many other sites. I don't think anyone will mind if the explanation is copied and pasted, even without a ulr reference as after all, it's just what an iso is or a byte is :-)
