Thanks Drage, I tried your suggestion and it works.
For what it's worth, there seem to be 2 ways of using this functionality with my version of ImgBurn which is 18.104.22.168
[INDENT]Using code as per your example, a fully qualified file name for each explicit file to copy, whereas quoting a path only, causes everything in that directory to be copied. It doesn't allow wildcards though.
Also, I saved a dummy IBB file with my settings, which I can use as a template, and by studying this file I see an additional syntax can be used to save the files in different directories to the source, or to rename the files while copying if I should wish.
[INDENT]This form uses notation such as "D|" to indicate that what follows is the directory to create, and "F|" to indicate a file to copy. It also appears to use the bar "|" as a delimiter to divide the line into sections for specifying the source and destinations of each file.
I will have to go away and a think about how to describe it in a clear and systematic way, although I'm sure one of you oldbies could work it out before I have a chance to get back here.
This second syntax somewhat defeats the purpose of quickly compiling a file list for a burn, but it was interesting to find out, and I could probably, given time, work out how to generate a properly formatted list using a batch file or my database.
So thanx for pointing me in the right direction.
