Greetings,

I have an idea I would like to develop but I don't have any idea on how to. I would like to attach some information to any kind of file, I mean, I would like to develop an application where I could give it a file and it just appends some information (like an specific userID, my harddisk serial number, my NIC MAC number, etc) to it and then I could easily extract it too.

I know (and I have even implemented it before) there are systems that do this with PDF files, but I would like to do this with ANY kind of files (or maybe with images, documents but not just PDFs). Of course, the file should be opened normally and function perfectly as it was before appending that extra data.

Any idea on could this be done in C??? Thanks.

It sounds like you want to wrap the file with data which would mean anytime the file was opened it would need to go through your program before it could execute again.

Yes, that's my idea, wrapping some kind of data that doesn't permit you to open the file until it's checked.
