Limiting files to a single computer
Dear Anyone,
I have prepared a few excel files linked together and am planning to sell it to a company. But they may copy and give these files to other companies to use on their computer. I want to protect my work. Giving passwords to open the files is not a solution because the first company to whom I sold the files may also give the password with the copy it makes. So, I thought the only way to differentiate one computer from the other is the Hard Disk serial number. If I could only link the opening of the files (or the whole folder in which they are) to the Hard Disk serial number, the problem would be solved! In this way, a copied file or the whole folder) will not work on the other computer, unless, I intervene and link the files to the new Hard Disk serial number. Any Ideas of how to do this? Or any other way is welcome. Thanks whoever answers. Berj Boshnakian |

How do you find a hard disk serial number? Even if it could be found, it
seems it would be pretty easy to circumvent that. Excel files aren't secure applications, after all. Dave -- Brevity is the soul of wit.
