There are many dates stored within files in Windows.  For many files there are several dates such as:

date created

date last accessed

date modified

date archived

date acquired

date completed

date last saved

date received

date released

date sent

date visited

date taken

And then there is a date column in Windows File Explorer called simply "Date".  This field in WFE seems to be populated according to what dates are available in a particular file.

It seems that some of these dates are controlled by the OS, and some are related to specific uses of files, such as for media.  I've read that the OS has rules about when it changes some dates, and the earliest allowed entry for some dates.

I've also read that when a file is copied (not moved) by the OS that the date created is changed to the current date and time.  This causes havoc when image files without EXIF date taken information are copied to another computer and then imported into WPG.

I'm describing all this because of the way WPG uses the available dates to display and sort images in the thumbnail view.  I've noticed that sometimes when importing new images into the Library, WPG uses the Date Created from the OS as the Date Taken for display within WPG.  This seems to occur for any JPEG file without an EXIF Date Taken, and for other types of image files without EXIF data.

This is all very confusing when using WPG and relying heavily on the Date Taken to control the searching and viewing of images.  It would be nice to read a short tutorial somewhere that explains how WPG uses file date information to determine which date it will use for the Date Taken data.

Is this information available somewhere?
