I plan to move data from XP OL2003 to Win7x64 OL2007.

I have found an Office Data File on the XP at ...\Microsoft\Office named
Outlook.NK2 that is 788 KB in size. There is no file in the folder with the
extension .pst. There are .xrs .xml outcmd.dat and OutLPrnt files in the
folder.

When I search C:\ including hidden files for any .pst file the result points
to the same location and name but now the size is 87,313 KB. Is/are these the
same file?
 
No. The PST file is your data file. The NK2 files is your autocompletion
cache.

Perhaps this will help explain the various Outlook files and their purposes:
