Discrepancy in timestamp of two files
Win10:
Hello,
I discovered a timestamp discrepancy when I look at a directory in Windows Explorer vs. Command Prompt. (Filenames scrubbed.)
Here's how it looks in windows explorer. The first file pair is in the PROJECTS folder, the second pair in a subfolder, to which I copied the files via the GUI (not command prompt):
And here's how they look in the command prompt:
Directory of P:\Projects
12/17/2018 04:53 PM 22,465 xxxxxxxxxxxxxxxxxxxxxxxxxD
02/22/2019 04:54 PM 23,726 xxxxxxxxxxxxxxxxxxxxxxxxxK
Directory of P:\Projects\TimestampDiscr
12/17/2018 04:53 PM 22,465 xxxxxxxxxxxxxxxxxxxxxxxxxD
02/22/2019 04:54 PM 23,726 xxxxxxxxxxxxxxxxxxxxxxxxxK
In the main PROJECTS folder, you'll note that the timestamps for the first two files differ between the WIndows Explorer view and the Command prompt view. (4:51p and 4:53p vs 4:53p and 4:54p)
However, after copying the files (the second two files you see in each example), the timestamps match. The COPY command apparently reset/refreshed the timestamp.
Does Win10 store more than one timestamp for files? (They are all PNG files.)
(Interestingly the time of day of the 2nd file in the Windows Explorer view of the top-level folder ( 4:53 PM) matches the time of day of the 1st file in the WIndows Explorer view of the subfolder.)
Thanks,
Steve
PS-On Friday, I thought I had seen the files not appearing in alphabetical order, but that's not happening now.

Yes, Windows stores multiple timestamps for files. 8 of them, to be exact.

"NTFS MACE (Modified, Accessed, Created and MFT Entry modified ) values . NTFS comes with 8 time-stamp values 4 of which resides in $Standard_Information attribute (SI) and the other 4 in $FILE_NAME (FN) attribute of MFT entry."
Windows Explorer can be configured to show which of these you want to see.

To add to the confusion, Explorer can display dates stored inside the file, in particular for multi media files ...
@Qlemo - by multi-media files, does that include PNG files created with the snipping tool,and possibly modified by MS PAINT? Thanks.
Open the properties of an arbitrary file in Explorer, and you'll see if there are additional informations in Details. For PNG, this is true, there is a recording date there. The software creating/modifying the file needs to manage that info, otherwise it is empty or unchanged.
In a test here, neither Snipping Tool, or MS Paint wrote to the date/time metadata tags in a PNG file. Paint.Net did write to a number of them, but not the date/time ones.

And the newer Snip & Sketch tool in Windows populated some of the other metadata, but not the date/time stuff.

@Bill - are you saying that if my PNG file is dated 2/21/19, 4:49 PM and I update it PAINT today, it will remain with visibiel date of 2/21/19, 4:49 PM? I've seen that behavior rather consistently.
Thanks.
Thanks.
No, I was referring to any date/time info stored in the meta data content of the file itself, not the basic operating system attributes associated with all files. Those will follow normal activities and be updated by Windows.
