How to change Date modified and Date created in file information

[stuartdo]

Hello,

I am new to the Exif tool, and to be frank I am not sure I really sure I understand how the command line abbreviations and code are supposed to be written. But this tool seems to be the one that has the most options for getting and using EXIF data.

I recently got a new cell phone and copied all my photos from the phone to an SD card, from an SD card to my computer, and then to another, larger SD card for the new phone.  In the process, my computer gave all the files new date created and date modified dates as part of the file information (not the EXIF data).  Over 3000 photos now all show up in the same day on my android phone, which uses the date modified entry to organize the photos in the gallery.

Is there a way to have this tool pick up the date from the EXIF and then re-write the date modified or date created (or both) entries in the file information? If you could show me exactly what to write in the command line, and an example of what it should look like when done, that would be truly helpful.

Thank you!

Hi Stuart,

Yes.  Here is the command:

exiftool "-filemodifydate<datetimeoriginal" "-filecreatedate<datetimeoriginal" DIR

Hi Phil,

I'm scanning old photos and I have Date Taken set to 1/06/1970 with increments of 5 seconds.
I have used your statement exiftool "-filemodifydate<datetimeoriginal" "-filecreatedate<datetimeoriginal" "D:\Temp\Date Zwarte Woud" to change dates and the strange behavior is that the date modified  en date created is now 31/05/1870 / 00:00:20.
I have also a QNAP Nas and have a drive mounted with a drive letter. When I execute the above code, nothing is changed?
OS: Wondows 10.

Due to a problem with the Perl date/time libraries, exiftool cannot properly set the file system timestamps to a date between 1900:01:01 00:00:00 and 1971:12:31 23:59:59.
