James, first just wanted to thank you with the past help, it has at least enlightented me on how CAP files are stored but am still having trouble storing the information which is important to me... looking at it, i do not need to modify mkhybrid to use the latest version of libhfs i just need mkhybrid to store fdLocation and fdFldr information from the FileInfo struct to the iso, which as i can see it is currently not doing.

any info on how this can be accomplished or what direction i should be looking into, would be greatly appriated.

-thanks again for the time -Bill
