I have a FAT32 flash drive full of old archived emails, and their creation/modification date is important because it represents when the email was received. I'm trying to copy these over to another computer (Windows 7, with an NTFS filesystem). I copy the files over, and it changes all of the creation/modification dates to the current date/time. I've tried manually copying through folders, using robocopy, and using xcopy, and have the same issue regardless. One strange observation is that, after I do a copy and have the destination folder open, the creation/modification times seem to be correct at first, but slowly convert over to the current time (when I click on a file, it has the correct date/time, but after a second or two changes to update to the current time; very frustrating).
Does anyone know a foolproof way to do copy over these emails while preserving timestamps?
EDIT: I can confirm that when I simply (single-)click on the file, its modified date is updated. Is this happening because the old modified date is newer than the creation date?
