PDF Property Extension
PDF Property Extension is a lightweight COM extension that brings back PDF properties and columns (like Title, Author, Subject, Comments) to Windows Explorer (File Explorer). It implements the IPropertyHandler interface for PDF files, required from Windows Vista® and later.
Works on Windows Vista®, 7, 8 and 10 (both x86 and x64).
How it works
Just install it and... nothing else.
Nothing to configure, when installation completes your Windows Explorer (File Explorer) will populate the additional columns (you need to show them by right clicking on the list header):
And the "File properties | Details" will show the new properties too:
Starting from Windows Vista®, file properties subsystem was deeply changed and the old IColumnHandler support has been removed.
The new IPropertyHandler interface must be implemented to let custom file properties (like Title, Author, Comments) appear in Windows Explorer (File Explorer).
None of the free PDF viewers I know, including the official Adobe Reader®, implement the new interface.
Some of them implement the IFilter interface that makes properties available only to Windows Search.
A trick/workaround to show PDF properties is to write somethinf in the "search" box in the upper-right corner of Windows Explorer, like *.pdf, but it's an uncomfortable solution for me.
But starting a file search just to show PDF titles was too much for me, that's why I wrote PDF Property Extension.
PDF Property Extension is free to use.
Donations are welcome, especially from professional/business users.
