Creating a file that cannot be opened?

Hi, I need to create a file that can be uploaded, but not opened. Does that make sense? I need something to go wrong when people try to open it.. can I create it in a different kind of document? Or just put a ';block'; on it?





Is there a way to do this? Thank you.Creating a file that cannot be opened?
what do you mean?!


to upload a file... ';you'; (or anyone else) must *open* it.


by ';open'; do you mean to load it into some sw? from where... from the web? or on a local machine?


you can lock a file... but if it is locked for reading, it cannot be uploaded to nowhere.

Encrypt it with a custom algorithm, and only you can open it. ;)





Unless of course you meant unopenable by anyone including yourself. In which case delete the decrypter... :P
