How do I write a letter for closing the old passport file?
No, I don't have any specific requirements. Can you give me a general template that I can follow?
Of course, here's a simple template that you can use: 

Dear Sir/Madam,

I am writing to request that my old passport file be closed. My passport details are as follows:

Name:
Passport Number:
Date of Issue:
Date of Expiry:

Please let me know if there are any additional steps I need to take or if there is any other information you require from me.

Thank you for your time.

Sincerely,

[Your Name]
