Tracing a file from a CD

[Jody7818]

I have this file on a cd that was copied from another cd. However, I have several CDs with the same file. Is there an easy way to find out which CD I used to make a copy of the file? In other words, do files or CDs have some sort of code that can be matched to another file or CD so that a user can detect from which CD the file came from?

i dont thing so. you cant find it from the cd but can use file properties. look all the files properties and write down dates that they created, modified. if you created them in spereate dates this can help. i hope it helps.
