Why would you expect a Windows property detail such as Title to always have a value? Some files do but many do not. The GetDetailsOf method is only getting a read-only property value. There is a DLL method that one can use to read and write to "some" Windows property details.

Some Applications like WordPerfect have properties that are not correlated to Windows properties. Sort of like Excel, WordPerfect has built-in application and custom properties.

Just to be PC, a Windows attribute is not a Windows property detail. I would be surprised if Q-Dir does not have an option to show Title like Windows Explorer has. Howsoever, even it does not show up, that has nothing to do with reading a value by GetDetailsOf method. You probably need to contact Q-Dir to report the problem. This is not a Q-Dir support forum.

For testing purposes, it would be best to manually add a value to a Title in Windows Explorer and then try the GetDetailsOf method.

Maybe Paul will do it but it might be good to make some routines to build an array that has the detail property names for the current operation system. One would then use WorksheetFunction.Match to find a match such as title. One can then use the index number plus one to get the integer for the GetDetailsOf method.

As Paul said, if you are 100% sure by manually setting a title value in Windows Explorer, then attach the file and we will test.
