Try right-clicking on the data file (on your folders list), choosing
Properties, then click the "Advanced" button and see if it tells you what
Format it is.

I have been reading prior posts regarding the 2 GB limit on PST file for
some versions of Outlook.

Is this unique to certain Outlook versions or does it pertain to the PST
file structure or both?

I am using Outlook 2007 but the PST file may have been created with an
earlier version of Outlook.

How can I tell about the PST file structure or which version created it?
