Notepad++ Date a Tab Opened

Question

I've come across a slew of threads about adding the date or auto-inserting the date, but I can't tell if there's a way to check the date of a tab that has already been opened.

Answer 1

Open the %appdata%\Notepad++\backup folder to see the list of open tabs.

Each file has the date/timestamp included in the name. If not, enable the Date Created column in that folder to know when a tab was created.
