How to view the user name of the last person that saved a file in the Windows 7 File explorer "Details view"

When you select any file in Windows and view its properties, you can see the 'property' this file was "Last Saved By" = "user_name"

How can I get this property to show up in the Folder's - Details view.

I can get the property "Date Last saved" to show up in the Details view, but I can't find a way to display the username of the "Last Saved by"

It's not available in the choices to pick up, can anyone else please help. Thanks. I originally asked this on stack overflow and was directed to the super user site.

  1. Run Regedit.
  2. HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SystemFileAssociations\.xls (Or whatever file type you want to edit.)
  3. Edit the PreviewDetails string adding whatever you want to show up in the order you want it to show up. To add the last modified by add this to the string: System.Document.LastAuthor;. If not sure what the value should be, open and look at the string in full details to see what it should be. You can not add anything that is not listed in the full details.

  4. Close the explorer window and when you reopen and click on that file type, you should see the value showing in the detail pane at the bottom.

You can try the "Owner" field column (not attribute as I originally posted). It's not exactly the same as "Last Saved By" but should do the trick 99% of the time.

In your folder view, right-click on a Column header such as "Name" then click "More...". Alternatively, you can click on View from the menu and "Add columns" then "Choose columns". Scroll down in that list until you see Owner and check that box. This shows me who was the last person to save the file which is what I was looking for when I came across this thread.

Could you edit your answer to explain how the OP would access the "owner" attribute? – Burgi Apr 12 at 12:34
With thanks to @G-Man " Users other than the owner can save a file, if its permissions are set to allow that, and this will not necessarily change the ownership of the file to the user who modified it" – Dave M Apr 12 at 12:35
The owner of a file never changes unless somebody explicitly takes ownership of it, e.g. with the Security tab of the property pages. Writing to a file does not update the owner. – Ben N Apr 12 at 13:07
Ben is right, the file's Owner attribute is an NTFS attribute that is not changed by saving to the file. The Owner column is what I should have said. Edited answer and provided steps. – Sergio Apr 13 at 14:36

You can try the 'lastsavedby' property; but I believe it only applies to files that are considered documents (e.g., Word/.doc*, Excel/.xls*, PowerPoint/.ppt*).

Go to the Windows search box at the top right and enter the following:


You will need to replace [user] with the user's first or last name; I don't think it will work with the NT username.

Your post provides useful information.  Unfortunately, it is not an answer to this question, which is not about searching.  Your answer might have been a valuable contribution to How can I see the available Windows Search Filters?, but the Advanced Query Syntax link was posted there over two years ago. – G-Man Apr 29 '15 at 15:37
