A strictly theoretical question...
Would it be possible to add some code, a sub-routine or procedure or whatever you call it, to a file--to a text file, an image, a sound file, whatever--that would cause it to be deleted at a certain time in the future? And add it in such a way so that it would not be obvious to anyone just opening the file?

I'm just curious, is all and this may be a really stupid question because of some obvious reason that didn't occur to me.

Thanks

Sort of possible. It usually involves some sort of certification that is held on a public server. The file is encrypted (look for public key encryption) If the certificate is deleted the file will not open. Mostly files like PDF also DRM'd files

For built in code, could be a sub-routine that creates a new file to delete the original. This would be very like a virus signature and probably picked up by AV. Linux would defeat this unless the whole thing had 'root' privileges (which the user would need to sanction).
