Win 10 - Preserve "Date modified" data when copying?

[Lamp0]

Whilst copying my music folder to another drive, I noticed the "Date Modified" field is updated in all the files & folders. I thought Windows preserved this data when copying?

 

Is this normal behaviour? Is there an option I can change or something?

Maybe try moving it to the new location, see if it preserves the date, then copy it back to the old location.

Interesting idea. I did a cut & paste which seems to still override the "date modified" field, but it does preserve the "date created" field.

Set the date of your computer to the date the file was modified before copying 

 

Humor aside, you can always edit those attributes afterwards, here's a handy utility: http://www.nirsoft.net/utils/bulk_file_changer.html

 

You can also use xcopy with the /e parameter in cmd.

 

Also the date only changes when files are copied to another drive, it does not occur when files are copied to the same drive.

Ah after looking at robocopy it seems it's the new default copy tool to replace xcopy in the latest few windows releases.

you beat me to it, Robocopy FTW! 

 

Such a superb command line tool, i use it extensively when moving files from one SAN to another and wishing to retain NTFS perms and modify dates. Ive done this to Petabytes of data over the years.

Richcopy is a gui front end for Robocopy, bettter for non tech users as you dont have to know the / switches.

it is normal behavior mate, your creating a new copy hence "modify date" changing to current date.
