How can I protect my excel file from copying?
Is there some way when someone copies file to another computer, that excel
file will not work?

Thanks very much

I think your only protection against someone opening the workbook would be
to use a password during File, Save As.

Yes, but what if someone use copy, paste to floppy disc. In that way excel
is not pretected.
I am asking this as I've seen one excel file which is protected in one way.
I don't know how but is not working on my computer.
It has excel file to enter data, and when you click button makes report in
another excel file.
I would like to have some protection in my excel, even in this way. Is there
some way that excel when opens checks folder from where is open, and if it
is not in right directory doesn't work, or something similar.

Thanks in advance

Yes, but what if someone use copy, paste to floppy disc. In that way excel
is not pretected.

But what good does that do this person? Without the password he cannot open
the file because it is encrypted. It is true that there are programs that
break passwords but if you choose a truly random password like "2#fH^;l45xa"
the password breaker may have to work for years...

How does having a button on a worksheet that runs a macro protect a
workbook? _Any_ kind of protection scheme that involves macros is
inherently very weak. All you have to do is disable macros and it's gone.

I guess I will put password something like you wrote.

Thanks Jim
