Is there a way to know the creation date of a folder?

Solution 1:

I don't think creation date is stored. There is a modification date associated with any file, which you can see by running ls -l in terminal (Ctrl+Alt+T should open it). But if you modify any file inside the directory, I believe this modification date is touched.

EDIT: Here's a more precise answer: https://stackoverflow.com/questions/14842195/how-to-get-file-creation-date-time-in-bash-debian. Seems like you can see creation date, using debugfs. But only for ext4 fs.
