Changing the "Date Modified" field of a file

I need to convert some pre-2000 powerpoint files to a current ppt format.  However, I would also like to keep the original "Date Modified" value.   Is there any way to either save the file without updating the Date Modified field, or manually changing the Date Modified field after I've saved the updated format?

    Yes<br> you can, at least with Windows 7 Professional and less current versions. Without using any non Microsoft commands.<br><br><br>FIRST:  <br> Open CMD.EXE with ADMINISTRATOR <br>PRIVILEDGES (put CMD.EXE on your desktop, R mouse Click, from drop-down<br> box click "Administrator..."<br><br><br>SECOND: <br> You are now at the "black screen" of the CMD.EXE program<br><br><br>THIRD:  <br> Type: DATE and Press {Enter}<br><br><br>FOURTH: <br> Type in some date that you want such as 01-01-2000 Press {Enter}<br><br><br>FIFTH:  <br> Type DATE {Enter} again, it should be the older date.<br><br><br>SIXTH:  <br> TYPE COPY /B (name of the file)+,, {Enter}<br><br><br>             <br> note bene: this is a BINARY copy using the plus sign(+) followed by two commas (,,)<br><br><br>                               <br> that uses Windows commands only. IT WILL OVERWRITE THE EXISTING FILE SO BE VERY, VERY, VERY, CAREFUL; make sure you have a back of of that file.<br><br><br>SEVENTH:<br> Check to see that the file date has been changed.<br><br><br>EIGHTH:   <br> CHANGE THE DATE BACK TO THE PRESENT.<br><br><br><br><br><br>Should<br> work, works here,<br><br><br>Good<br> Luck,<br><br><br>jrd

    You can manually change the Last Modified Date/Time for a file using a free software called Attribute Changer from http://www.petges.lu/. You will need to remember the modified date/time of your presentation file, modify the file and then use Attribute Changer to set the modified date/time to the previous one.

    Unfortunately it’s not possible to manually change the modified date of any file in Windows.

    If you do not want to change the modified date of the original document, you will have to recreate the file or copy the contents of the file in to a new PowerPoint 2010 document,

    Chirag,

    Thank you for the suggestion.   I was able to change file attributes on ppt, doc, and xls files using Attribute Changer, but not all of the time.   For example,

    • I have a ppt last modified in July 1995, that I cannot read with the current 2010 Powerpoint.  When I try to use Attribute Changer (AT), it responds "These objects are locked/enountered problems".  The only attributes I can see are "Ready for Archive" & Allow Contents to be Indexed".
    • I read the file with Powerpoint 2002 and save it as a ppt.   However, Attribute Changer give the same error message.  Does the same thing if I take off the Archive flag.
    • I read the PP 2002 file with PP 2010, and save it as a ppt.  Now, Attribute Changer will allow me to alter the Date Modified.

    So, I can do what I want to do but it takes an extra step.  Any thoughts on why Attribute Changer won't work on the PP2002 file? 

    Tks

    Dave
