minch-dev / WinCopyPasteDates

Windows context menu items that allow you to copy a given file's date stamps and then paste (apply) them to any other file. Applies all three datestamps, 'modified', 'accessed' and 'created'. Helps me to preserve dates for archival purposes. Might be usefull for anyone else as well.

creation date inconsistency #3

Closed minch-dev closed 2 years ago

minch-dev commented 2 years ago

For some really unobvious reason the rename cmd directive changes the file's creation date to... ehm... ~batch file's creation date~ the previous file's date of the same name that gets deleted at the beginning of the batch script. That must be the strangest bug I've ever encountered and something you wouldn't expect from some basic function like this.

Basically as far as I understand this is the bug in NTFS journaling system itself. I've already seen this behaviour before, when you delete some file and rename some other file to the name of a deleted one the creation date for some reason is getting rewritten by the deleted file's creation date. Indeed that's some really strange behaviour and for an old and proven system like NTFS filesystem is it's pretty unexpected to have programming errors like this at all.

Fixed, also added .lnk files support while I was at it.

And just when I thought the issue is fixed, NTFS strikes back with the same issue again.

Oh, basically it's a "feature" of NT based systems, wow, nice. https://web.archive.org/web/20140528165711/https://support.microsoft.com/?kbid=172190

These paired operations can cause tunneling on "name." delete(name)/create(name) delete(name)/rename(source, name) rename(name, newname)/create(name) rename(name, newname)/rename(source, name)

Fixed with the help of timestamps and random numbers, let's hope it's a final fix.
