Hello, I’m Virginia, I have 20 years of expertise in fixing my own & friends’ PC problems.
Sorry to hear you’re experiencing problems.
Date created is the date when the file was originally added or created using an app or program.
Date Changed/updated is the time/date when the file was transferred to another device (from phone/camera to PC or between drives) or when it was last edited via an app or program.
I hope this answers your question.
