> Will this help in legally binding claims?

Not her words, but it can help prove that something existed at a point in time. It doesn't necessarily mean that you were the first but it does mean that you had it at that point in time. As I understand it, in copyright practice you take a work you've written, put it in an envelope and send it to yourself. The postmark shows that it existed at that point in time. (You don't open the envelope until some sort of legal procedure makes that required.)

Exactly, it's a light-weight way to record that you had a file without storing the whole file.

I should mention the word "Dibs" is a bit slang for meaning "i had that first" https://www.reddit.com/r/NoStupidQuestions/comments/nz92om/w...
