From what I've discovered, the XMP:DateTimeOriginal has the least priority, so it's used first, while the EXIF:DateTimeOriginal has the highest priority, so it's used last. It uses the fact that when ExifTool has two assignments that affect the same tag, the latter takes precedence. This will set the FileModifyDate by trying all the various metadata Windows uses for the 'Date Taken' property, in order of priority. So the best command for you to try would be:ĮxifTool '-FileModifyDate exiftool windows 10

The mostly likely tag (and the one Windows gives highest priority to) is the EXIF:DateTimeOriginal tag. Windows fills this property with different metadata, depending upon what it can find. The usage is very simple just drag the file and drop it on ExifTool(-k).exe and this action will open in a command prompt with all the meta-information.

Assuming you're using Windows, part of the problem is that there is no 'Date Taken' tag. ExifTool is a platform-independent Pearl library plus a command-line application for reading, writing, and editing meta information in a wide variety of files and it’s a portable application.
