Micro$oft breaks Win 10, Again

Back in Windows XP, you were protected against accidentally copying a old version of a file over the latest version of the file.  Wind 10 no longer protects against this.  There I am backing up Trusty Desktop onto Flatbeast my laptop.  On Trusty Desktop I copy my recent files, such as my checkbook, my list of books, my medications, a bunch of photos, and other stuff onto a flash drive.  I carry the flash drive over to Flatbeast  and start copying the latest versions of the files off the flash drive onto Flatbeast's hard drive.  Of course,  I have done this in the past, and Flatbeast's hard drive already contains old versions of these files.
  Back in the good old days of Win XP, you would get a message box saking "Do you  REALLY want to overwrite file such-and-such date such and such with  same file name, date somthingelse?"   And you would look at the file dates, and most often you would say "Go for it" if you were overwriting an older file with a newer one.
   Now we are stuck with Win 10 and we get a similar message box, EXCEPT,   one of the file dates comes up as "Unknown".  So the question now reads "Do you REALLY want of overwrite file such-and-such date such-and-such with same file name, file date UNKNOWN?  
   Of course you don't want to do that.  Do you?  So maybe you don't back up your files, maybe you say "Press on regardless", maybe you do some double checking.  But on Win 10 you have a lotta ways of messing up in file back up which good old Win XP handled correctly.
   Looks like the  Micro$sofies have been spending programming effort in breaking things that used to work.
