Access/Modify File Info/Properties of a Text File [C#]

[Shaitan00]

Goal:
Given a Text File “Test.dat”, I need to retrieve the date on which the file was last Modified & Copied to a specific location,

Problem:
The file can be transferred (copied) via any method to the specific location and must retain the required information however protocols like FTP change/destroy the original Created/Modified/Accessed date thus rendering them useless.

Possible Solution:
Use one of the other fields (in Summary for example: Keywords or Comments) to store the Timestamp prior to copy, this way windows should not be able to destroy the information. Please confirm.

Create a new field (in Summary for example) to store the timestamp. Please confirm.

Given these requirements, if it is even possible, how could I write/read from the File Information, like the File Summary Properties for example?

Check System.IO.FileInfo Class .

I wish it was that simple, already checked FileInfo Class and the information is not there.

Actually IPropertySetStorage Class is what is needed.
But to crazy for my requirements.
