help: Restrict access to Excel files

[thunder_anger]

Dear all

after i worked hard on my file
i want the file to open just in one computer and if copied to another computer it won't work

is that Possible?

Encrypt the file with a good encryption tool (such as TrueCrypt). Don't rely on Excel passwords or macros. Anyone interested enough in your file to copy it and put it on their computer will quickly bypass ordinary Excel security which is very weak.

Another approach might be to keep the file in a directory with restricted access so no one can get to your file in the first place.
