"Date Modified" changes on original file when copying

Wow that is interesting. Now that you mention that I did try to install something that I originally used for XP called "NinotechPathCopy". That was before I found out you could hold "SHIFT" and right-click in Win7 to "copy as path". At the time I tried installing the NinotechPathCopy it did not work so I assumed all was good but maybe it did actually install something. I will have to check on that as it could be what is causing my problem.

I cannot replicate the problem in question. Doing right-click drag and copy the modified date remains the same, moving it remains the same, left-click drag and copy to another drive stays the same... Maybe you have something, like an anti-virus or explorer extension that is doing something with the file during these copy operations.

Very good point. It certainly could be an A/V "on-demand" scanning of the files when they are accessed (in this case being moved/copied) which then modifies the files.

I looked under "Programs and Features" and could not find anything to uninstall. I will have to look at the inf file to see what registry entries were made and maybe I can remove them.

Thank you Logic Earth! I'm still using XP; I found this forum by Googling the problem. Right-clicking and dragging a file (or a whole folder full of files) and selecting "copy" from the pop-up window, does indeed preserve the file modified dates in the copied files. Simple!

Why Microsoft does not make this info clearly and easily available, is mystifying to me. But no longer surprising.

i saw the notice "The last post in this thread was 183 days ago. If your post is not directly related to this discussion please consider making a new thread."

but i have same problem. and read through the topic, and same problem.

i copy (ctrl c) the picture from usb drive which has date 01/01/2011 for example. after paste (ctrl v) to local drive, date modified changed to todays date which is 15/02/2011.

is this kind of new behaviour of windows 7? if it is so-called "by design", i only can say, WOW!

I am using skydrive. I have noticed that upon uploading my files the "date modified" for each file is changed to the time that the file was uploaded.

This seems to violate the presumption that you are archiving an actual exact copy of the original file. I must retain an exact copy of the original.

Does anyone know how to get skydrive to not modify the original file?

I am using W7 64 bit.

I recreated the problem and have attached a screen-print showing the problem. To create the problem, I opened up two explorer windows and then created an empty directory in my skydrive called temporary. I then dragged the 8 files using windows explorer to the skydrive temporary folder at 4:37 a.m. (Saigon time)

That was the time the "aboutsyncfolder.pdf" was created on my D drive.

The same file on my skydrive shows it was created at 9:38 a.m .... but this is not true ... it had to be 4:38 am (exactly 5 hours different) ... The other files all show being created in skydrive at either 9:13 or 8:51. I don't know why this is. They were all dragged and dropped at the same time. I've repeated this many times and it gives the same results. I've disconnected and reconnected my Gladinet skydrive.

I'm in Saigon doing this ... could it be some sort of problem in timezones?

This is a problem that occurs when files are copied from ONE DRIVE to ANOTHER.

Even I would like a SIMPLER SOLUTION where the COPIED or MOVED Files & Folders RETAIN their DATE/ TIME STAMPS:
- Creation Date
- Last Modified Date
- Last Accessed Date (Not critical but nice to have)

Its simple but the only way for me to do this is a set of complex steps using RichCopy/ RoboCopy.
