[Changing EXIF to Modify Date]

[newtothis]

Hello all,

I'm sorry if this is such a basic question, but I am having a hard time...

I want to get all pictures and videos in a folder, and change their EXIF (original) date and Create Date to the Modified Date. That is, they should all take the Modified Date. I searched for my problem and found the following code:
exiftool "-alldates<filemodifydate" -P DIR

but I do not know how to apply it for one file, let alone a batch... Can anyone help me out?

Thanks!

I just figured out I should update DIR with the directory where my files are. lol
sorry

You should have seen this message when you ran that command:

Code Select Expand

You were meant to enter any valid directory name, not "DIR" literally.

(you weren't the first person to make this mistake)
