I have been sent some rar files. I was told to unrar them to make an ISO image to put on a disk. When I use winrar on them all I end up with is one large file, which, as far as I can tell is still in the rar format. Can anyone help?
One singe rar file made up of the individual ones. Cannot process this file in anyway to make sence.

I have had that myself from time to time.
I think that whoever makes the rar has the wrong file extension name initially.

It will be an ISO file and shoud burn ok.

Make a copy of the file, just as a safety measure, then rename the extension from .rar to .iso and burn as an image file.

You may have to open a folder and go to Tools/Folder Options/View and untick the box that says "Hide extensions for known file types" to show the .rar or whatever extension it is as part of the file name.

Hi Sandra
Should I rename all the files to .iso or just the one large file they make when they are uncompressed.
I tried just renaming the large file and that was not recognised as a .iso image.

Just the last one should have done it

When you started off you had lots of rar files all numbered as 01.rar, 02,rar, 03.rar etc I assume.

You should have them all in the same folder, preferably with no other files in.
If you right click on the lowest numbered rar file and select extract here then it should automaticallly unpack each file in turn and reassemble them into eaither a single file as an ISO or more often as 2 files, a cue and a bin file.

Is that the procedure that you used but it made a single file still called a rar ?
Is the extension a rar or is it just part of the name ?
It may have actually made a file with the .iso extension but still have rar in the name and in that case should burn as an image file without having to rename it.

Hi Sandra
I managed to extract the files to one single file called .iso. But this is not recognised in any way. I tried a programe called iso buster, it could not
find any files or folders in the iso image.
Kind regards.

you could try a program could alcohol 120% which should allow you to mount the image, but it is not free. Or, since you have the ISO you should be able to burn off this image to a cd or whatever

Hi Sam
Thank you for your reply. The iso image on cd is not recognised and iso buster says it cannot find any content in the image.
Thanks.

well try and burn it with Nero or something similar.

Hi Sam
The image on the CD is not recognised and iso buter cannot find and files or folders on the CD or the original file.

sorry am i missing something.. how did the iso get onto cd?? why is isobuster looking at a cd? Surely the iso image you extracted from the rar files is now in a directory on your hard disk? Or am I completely missing the point, which to be honest is pretty possible! :-)

If you have nero installed you will need to select the burn image to disc option. Then browse to where the ISO image is and open it (making sure that the appropriate file extension is in the drop down box below ie .iso or you could choose all files) and away to go.

It sounds like you may just have copied the file to cd not burned the image.

Then after that just put the cd in your drive and it should auto start with whatever the image contains.

sounds like a plan of action.

How big is the original multi rar file ?

Is it something thats not private that you could email to me so that I can possibly see what the problem is ?

Just click on the email link under any of my posts if you want to send it to me.

Hi
I will go over again. I was sent some rar files with the instruction to unrar and make an iso image to put on a cd. I have managed now to make one iso image from the rar files. This I have put on to a cd, this image is not recognised at all. I have used some software called iso buster, this can extract the files and folders contained in the image even before putting onto a disk. This software says that it cannot find any meaningful information in the image, either on the hard drive or on the disk.
Kind regards.

Ok then. I know how ISObuster works, have used it on many occasions.

So have you just plain and simply tried to burn the disc image onto a cd... i.e. the burner in disc image mode. Here is how I mean: http://www.wizardskeep.org/mainhall/tutor/neroiso.html (or http://trb.org/publications/burning_iso.html).

Instead of using isobuster you could use Daemons to mount the disc... here is the link http://www.daemon-tools.cc/dtcc/download.php?mode=ViewCategory&catid=5 - though watch out for spyware. I don't believe this will install them.. but it suggest it might install some unwanted s**te.

There is also, as I mentioned before, Alcohol.. but it is not free.
