Text document symbol query

I just have a quick question of something small I don’t understand. In my drafts folder I have a few text documents set up. The symbol for most of them is just a page with writing (I assume this means because its a text document in which I have writing) and some have the same page symbol but it is folded down in the corner, what is the significance of this?
I use Windows.

I hope my question makes sense.


‘You can tell if a text document has any associated snapshots by its icon. Documents
that have had snapshots taken of them have the top-right of the paper icon folded down
in a “dog-ear”.’

This is from the tutorial, and is possibly what you are seeing.

Ok thanks! You are correct! I looked through the manual but couldn’t find the answer, thanks very much!
