Hello Richard,

Thank you for your help. I get back a number. It is working.

Do I understand the code right: F_open creates a file handle which you pass to GetFileInformationByHandle.
DwVolumeSerialNumber is a volume serial number, all files on that volume will have the same dwVolumeSerialNumber.

Do you know what happens if you xCopy one SDCARD to another.
Does the dwVolumeSerialNumber remain on the copy the same?

Thanks again,
Otto

Every SD card has its own serial number

if you "xcopy" all the files from one to another, you do not copy the serial number , you can just retreive it

Richard, thank you. That is good, that is what I need.
So I can use this number to protect the software.
Thanks again,
Otto
