IsoBuster can create image files. Supported features are creation of a cue-sheet file per CD/DVD image and file splitting.
Split Image files in multiple files during creation :
For several reasons it can be interesting at times to create image files split up in several files.
E.g. Image.bin, Image.bin01, Image.bin02, Image.bin03, Image.bin04
IsoBuster can load these Multi-File images without a problem and you can still get all the data from these split up image files.
One of the reasons for this feature is creating DVD image files on a Windows 98 FAT32 formatted HD.
FAT32 can only cope with max 2 GB files and DVD images are often 4 GB or larger.
It is common practice in this case to split up the images in chunks of 1 GB each, hence 1 GigaByte (1GB) or 1024 MegaBytes (1024 MB) is the default setting. However you can create image file as small as 1 MB. The smaller the setting, the more files will be created, so be careful that you don't overload your system by creating more than 4000 image file chunks.
Note.
IBQ files are automatically split up around the 1 GB file size boundary, if the size is set greater than 1 GB or not set at all.
Create Cue-sheet files (*.cue) :
Cue-sheet files (*.cue) were originally designed for CDRWin but they are commonly used and combined with image files to have a feel for the track layout of the CD. Cue-sheet files (*.cue) are in fact text files (you can open them with any text editor). The actual CD data is always contained in a different file (*.bin, *.iso, ...).
So if you open a *.cue file with IsoBuster, IsoBuster will know the track layout of the image but will get the actual data from another file (*.bin, *.iso). This file's name is also contained in the *.cue file.
IsoBuster can also create these files. Default, IsoBuster will prompt you each time after you made an image. However you can also set the option to always automatically create a cue-sheet file after creating an image, or you can set it to not be bothered again.
Cue-sheet files have limitations !! They're nice to get the track layout of a session, but they do not support Multi-Session discs. IsoBuster however adds features to the cue-sheet file so that Multi-session discs are supported as well. These entries are preceded by "REM" so that other applications (that do not support Multi-session cuesheet files) do not complain. However, if you load these cue-sheet files with IsoBuster again, you get the full potential of these added features and you can see all sessions again properly.
Additionally to the option to create cue-sheet files after creating an image, and totally independent from this option window, the right mouse click on a CD/DVD icon option also provides a means to create a cue-sheet file, without creating an image itself. This feature is nice to create and share a layout of a disc without having to create the entire image. There's once catch, cue-sheet files list the amount of bytes per block that were extracted in the image. If you end up using a cuesheet file created with this option you have to make sure that the block size matches with the image itself.
Create MD5-checksum files (*.md5) :
MD5 technology is great to flush large numbers of data through to in the end get a 16 BYTE checksum that is very unique. MD5 technology is used a lot as a means to identify if a file is still exactly the same as before. Many files these days are accompanied by a *.md5 checksum file which contains the 16 BYTE checksum. Third party checksum testers can then be used to verify if the file is still exactly the same as before, e.g. to verify that the file hasn't been altered, edited, corrupted during transfer, ... .
IsoBuster also features MD5 check and creation functionality.
It is possible to specify in this option to always create an MD5 checksum file after an image file has been made.
The just created image file is then automatically opened and a checksum file is created from that image.
More on topic :
When an image file is opened by IsoBuster, a user can choose (right mouse button click on the CD/DVD icon in the left pane) to create an md5 file from that image or to verify that image with an existing md5 file.
IsoBuster can even create an md5 file from a CD or DVD before an actual image has been made, the user can choose between as if the extraction would occur for user data only (2048 bytes/block) or raw (2352 bytes/block).
If an md5 file is opened with IsoBuster as if it were an image file, then IsoBuster will treat the first file mentioned in the md5 file as an image file and will automatically do the MD5 verify for this file.
If an image file is in fact a combination of more than one files, then IsoBuster will handle that all automatically.
ISO / BIN / TAO :
Traditionally, IsoBuster has always created TAO and BIN image files. An image created with user data only was a TAO file, an image with raw data was a BIN file. To avoid confusion and because ISO can be basically either user data or raw data, it is possible for a user to set that IsoBuster always creates ISO files, no matter if the content is raw or only user data. It is adviced then to also create a CUE file, as that file contains more information on the way the image was extracted.
Files associated with IsoBuster :
IsoBuster supports a wide range of image files. During installation you can set which files should be associated with IsoBuster. File association means that, if you click a file with a certain extension, that file will automatically be launched inside IsoBuster. The option here enables you to associate when you forgot to do so during installation, or to deactivate association when you so desire.
