What's the difference between "date opened" and "date modified?"

[eroxx]

I saved a file into a folder that I had not once opened, and yet it said that it was "opened" at the time that I saved it ... Can someone clarify?

Folders apparently must be "opened" to save something to them.

I'm using hazel to make rules, and that's why I'm wondering the difference ..

In folders, think of date opened as actually meaning date accessed. So ANY activity inside a folder will update this date, even copying or moving files. Date modified, of course, would only update on a folder if you were to rename it, for example.

What about files in general?

With folders, think of it as a closet, you open something to take something in or out. You can't just defy the laws of physics and squeeze something through the closed doors With all other files, unless you actually add, delete or modify data, "Modified" isn't going to change.

Hazel is awesome!
