I often have a need to add an additional file or folder to a disk when burning an iso file.
The process I used to use was to burn the iso file, then copy the contents from the CD to my HD, add the new files or folder, then burn a new CD from the folder with the modified files, wasting a CD along the way.
Then I found virtual drive programs like Alcohol 120% that would allow me to view the contents of the iso file,
copy the files directly to my HD without burning a CD, add the new files/folders, then burn the CD.
Currently, it appears that Imgburn cannot burn the contents of an iso file directly to a folder on a HD, or allow a user to add any files/folders to an iso file.
This would be a great feature for individuals like myself who would like to add to or modify the contents of an iso file,
such as adding a readme file, adding a documentation folder, adding a serial number, etc. to the original contents without
having to waste a CD to do this.
