Question: Reading File Dates

I want to read file dates (for data files) from inside Maple.  Specifically, I want to automate the comparison of access dates.

I thought I'd done this in the past, but my attempt to recreate it has led me to think that I am remembering incorrectly.

Is there a way of doing this?

I don't deeply care about portability (I'm working on Windows 10 and that would be good enough), but since I'm asking the question please comment on the easiest way to make this portable.

I am aware that by default Windows 10 doesn't update the access date.  On the machines I care about, I have changed the configuration so Windows is updating the access date (often enough for my purposes).  I have PowerShell scripts that work correctly.

Please Wait...
