Creation date to backed up files

Hi Just bought and installed WD passport noticed that all files are now dated with todays date they have lost all original dates - that’s a pain
Also have to click on about 10 directories before I get to the one that contains my files
Gee its slow preparing for back up and have noticed that all files are not backed up
Any ideas to change
I am not good on computers so I don’t want to delete anything or change directory names

If it’s the “Created Time” field, the MPW’s Linux system will follow the Date Modified time. Here is an article for this:
