Windows Explorer file dates not matching dates shown on file properties [duplicate]

What is the “Date” column in Windows 7 explorer? It matches no date column from Windows XP explorer

Notice the Date (modification date) column in the Explorer detailed file view. When I get properties of that file however, the dates are completely different. Refreshing Explorer did not help.

What is happening?

I got the same problem for years and searched for a workaround and a behaviour to sort files (specially pictures) to look on different devices and keeping a unique archiving method. I copied or moved entire folders for backup , etc ... In the end, I could not rely on file date. I constantly have to pay attention to date modified or created.

Have a look to some explanations at microsoft solution center. Description of NTFS date and time stamps for files and folders

A good solution would be to update date-modified and date-created in a batch process after copying or moving a whole bunch of files. For example, you could do it with a php cli script.

About your problem, you have date-created and date-modified, access-date and date-taken. All of it is the same the first time when you take a photo (jpg) in your camera. Date is generally date-modified, may differ according to file type.

To manually tweak file dates, I recommand you StExBar - Explorer Timestamp eExtension or dirdate
