putting my name on a file

[kap]

I have been strongly advised to hard code (?) my name on every projects and files I create if I am to earn my credits with the boss. How do I do that? Currently, I am creating spreadsheets in Xcel and Access on a Windows XP machine to keep track all the small student loans, i.e. the funding source, who has it, how much has been spent, has it been paid, and how much is still owed.
