This is what happens if you just copy a file from your memory card to a folder. Windows changes date modified. Here is an example.

This was discussed in detail about a month ago, when Jutilda got the DQ.

| That should be okay. Date modified is older than date created anyway, and should match the date and time taken... I think... |

Maby I am getting it wrong. I did not open the file in any program I just copied the folder from the memory card to my desktop and this change happened.

The create date is when it was created on your computer. The modify date is still the original date (which is before the create date).
The SC would be able to better explain this but I don't see an issue as I don't believe it's a Win 7 issue. When a file is created on your computer, the date is recorded. |

But she opened the file in a program. I did not open the files just copied them. |

Did you "copy" them using the "copy/paste" commands or by "dragging and dropping" them? Using the latter method is recommended (regardless of the computer OS) and should not change the dates or anything else about the file(s). |

| I reckon it's the workings of the file system. Copying the file does not change the exif or date last modified. Even on WinXP, if I copy a file directly from the card, the date created will change to the current date/time. Always have done so and got the shots verified. |

The date showing on the hard drive might change, but the date(s) in the EXIF should not change. Still, when I drag files to the hard drive using Win2000 (or Mac OS 9/X), the date still shows the same as the creation date on the card, not the date time I copied the file. |

| It's possible that there's a parameter that you can set that will preserve the creation date. |

Copying in some OS's creates a new file that is exactly the same (byte-for-byte), with the same date modified, but with a new "date created." After all, if you make four copies, rename them all different ways, and put them in the same folder as the original... how do you know which is which, except for the file names? Moving sometimes copies and then deletes the original, so it may cause the "date created" to change as well.
But it really doesn't matter. Date created is a file attribute that may get changed when the file is moved/copied, but the date modified stays the same - it is "stuck" to the file until the file is, well, modified. So keep your file intact but copy it as many times as you want... so long as the contents are the same (you didn't rotate or anything), you're fine. That way, your date modified will match your date taken.
Anyone know if tagging changes anything? I think it's also a file attribute, and it seems that changing only file attributes doesn't change the "date modified." |

So, here's the low-down on the Win 7 OS behavior:
- When a file is copied, the creation date becomes today's date, because the copy you are *creating* was made today.
- When a file is moved using cut/paste, the creation data remains as it was, because you have moved an existing file, not created a copy.
Dragging a file from one folder to another will produce different results, based on where the source and target folders are:
- If the folders are on the same drive, dragging results in a "move" operation, and therefore retains the original creation date
- If the folders are on different drives, dragging results in a "copy" operation, and therefore the creation date(s) will be today's date
All this behavior is internally consistent, and none of it has any relevance at all to whether the resultant files are valid originals. The *only* time a file is invalidated as an original is when the file's internal information has been changed, not when the information used by the operating system is changed. This tracking information is not a part of the file, it is information maintained by the OS>
