Windows 10: FILES COPIED CHANGED THE CREATED AND MODIFIED DATES TO THE DATE COPY WAS DONE???

Files created over many years were copied form PC WIN 7 to a portable hard drive then my new PC WIN10

File creation dates and modified dates changed to the date copy was done.

For my purposes this is disastrous.

One answer was I should have used "move" instead of "copy". My understanding is there is absolutely no difference.

Why does it do this and
how can I remedy please?

There is a program called File Date Correctorthat is badly reviewed so hard to trust it and when I went to install a trial copy WIN 10 put up a warning saying not to trust it.

Any help is appreciated

:)

 

Random "date modified" changes in copied files

Thanks for your answer.

I followed your advice and found that actually the issue seems to disappear when in safe mode (both F4 and F5). I tried copying some
exe and js files and I got no date changes.

As soon as the PC was booted normally the issue came back again. Copying the very same files to the very same destinations I had their original "modified" dates immediately changed to today and copying them again, overwriting or deleting+copying, I had their
original dates kept unchanged.

Moreover, I noticed that once overwritten and "fixed", the files seem somehow "switched" for good: if I try overwriting (or deleting+copying) them again the original dates are kept, as if someone had... learned the lesson, at least for a few minutes AND
as long as I use the same destination folder.

Choosing another folder OR waiting a few minutes makes everything start over again.

 

How do I modify file date created?

Hello Robert,

You can modify the date created by copying a file. The file's created date becomes the modified date and the current date (when the file is copied) becomes the created date. You can copy a file on your PC to check.

Let us know if you need further assistance.

 

Random "date modified" changes in copied files

I noticed, a few months ago, that sometimes my copied files (from Win10 x64 system disk C: to external NTFS USB disk D: used for manual backup purposes) do
not keep the same "date modified" as the originals (as usual) but get that date automatically changed to the date (and time) of "today", i.e. the day when the copy operation is performed.

Which is obviously a mess, because the real "date modified" (on which comparison and backup procedures rely on) gets lost.

I got aware of such a weird thing thanks to a file-comparison program I've been using for many years in my manual backups, which suddenly marked some files in D (even if just copied!) as different from their counterparts in C because of the different dates.

While investigating, I noticed that this seems to happen in a quite random way. I can drag and drop an old file from C to D, see that the copied file has got today's date, drag and drop it immediately again (overwriting) and see that the
copied file has kept the same date as the original. Sometimes I have to repeat the overwriting two or three or more times in a raw before I eventually get the same result.

So: the exact same user action produces quite different behaviours, which clearly isn't good at all, especially when coming from an operating system.

Furthermore, the problem seems to "prefer" some file
kinds, such as "exe", "js", "ini", "bat" ...

I really did a lot of searches but sadly I did not find any useful help.

I hope someone here will be able to shed some light.
