I've got such a cool machine that's why. No, I will not sell it to you.

When I copy and paste a file to any location, the creation date is always today's date. If the file already exists, the file name is automatically renamed to "Filename - Copy.xxx". I don't know why it behaves differently on your machine?

Test #1. Copy a dwg file (dated 3/1/2004) into the same directory it resides in.
Result: Using Windows XP Pro the file gets preceeded by the words "Copy of xxx.dwg". The date of the file remains unchanged. The file size remains the same as well.
Test #2. Copy the same drawing file from my hard drive onto my USB flash drive and into a folder containing the exact same drawing.
Result: I first Copy, then try I to Paste. Up pops a window with the message: "This folder already contains a file named xxx.dwg. Would you like to replace the existing file with this one?" There is no way to easily put a duplicate file in the folder on the USB flash drive without overwriting the file that resides there. One would have to rename the file first. Example: xxx[rev].dwg.
Test #3. Copy a drawing file (dated 1/19/2001) off my hard drive to my USB flash drive. Does the file date change in the process?
Result: No, it does not.
Is there another senario you would like me to test? Edited by John Connor - 15.Mar.2011 at 15:37 |

When I say "Copy" I'm referring to the action of right clicking on a file in windows explorer and then copy and paste. Are you talking about saving out a copy of a file from within the program?

Maybe I'm confusing "saving" and "copying".
Anyway, with the past couple OS releases when one copies a file doesn't Windows denote the copy in some manner automatically? I'll have to check.

I think the date would change if I were to do it, but you're saying the creation date does not change when you copy files on your computer. I'm not sure why that is?

So you're saying if iIwere to copy all the files off the 3.5" disks I have for AutoCAD for Windows 3.1 and put them on my hard drive the date for each file would change?
Win7 64-bit Ultimate too. Must be our great minds thinking along the same lines! |

I don't know how that can be? If you have a file that you worked on a
year ago, it's creation date is one year ago. So if you make a copy of
that file today, it's creation date should be today because the copy was
created today. I don't see why it's creation date would be one year
ago? As far as you're concerned, it's an exact copy of the original
file, but as far as your computer is concerned, it's a new file that's
just been created.
I've just done some searching but I couldn't find a way to copy a file and keep the same creation date without using some 3rd party software. I don't think it matters, but what operating system are you on? I'm on Windows 7 Ultimate. |

I copy files to my flash drive on a weekly basis and there is no change in the date or time. Different settings?

Not necessarily. It's true that the file size would be the same, but the date and time it was created will be different. Take a look at the screenshot below. The file properties on the left are from a file I worked on Friday at work. I stuck it on a flash drive, brought it home and copied it to my desktop. That's why the modified date is March 11 and the Created date is March 12. The file properties on the right are from a copy of that file that I just made. The date and time created are different. I did nothing to the file other than copy and paste in windows explorer. The file was not opened at any time today.  |
