As far as I know you cannot except to password protect the document and/or the computer, so that no one can use it except by knowing the password. It depends upon the program how to copy protect the actual report. But I have never been told about anyway to make a document that cannot be copied in one fashion or another.
Terrel is right. As far as I know you can't. You can trun on password protection so that you have to log in. You can also set up you screen saver so that you have to type a password once it becomes active to access you computer. Thats about the best you do and I think I could still copy your files if I really wanted too. Most people probably wouldn't know how though.
You may want to consider the purchase of a 'portable desktop' a powerhouse laptop with connectivity through a replicator port (which lets the laptop fully emulate a standalone machine) that you take with you when you leave...
Not to be nosy, but why would you be involved in a situation where you were unable to trust the persons sharing office space? 8O
You may be able to cripple the floppy in the BIOS.
You should see a screen flash by when you start up you computer that asks if you want to change the system settings. Access is different for each machine, sometimes pressing the <F5> key at start up will get you there.
The down side is that if the harddrive dies you may not be able to boot from a floppy to fix the problem.
If you have an internet connection on the computer if some one wants the file they could just email to thier machine.
You might have better luck getting one of the computer untility programs like Norton and encripting the directory where you store the files and password protect that directory.
