If you can provide the first 50 or so bytes from the beginning of the file in hex, someone might be able to identify the program that created it.
One way to create a file containing a hex representation of the contents of one of your CD files is to use this command, which comes with windows. certutil -encodehex cdfile hexfile It only works with files having a size of 21,510,272 bytes or less, otherwise it produces nothing. The limitation seems to be that the size of the output file cannot exceed 102,400,000 bytes. If you add another operand, the number 4, the format of the hex output is reduced and the input file size can be up to 32,768,000 bytes. certutil -encodehex cdfile hexfile 4 Bill On Sun, 18 Apr 2021 12:12:36 -0500, Hilario Garcia wrote: >I have a CD with download of several PDS files.
