Yong,

I would: (1)  Take the text from the PDF, while keeping the text tied to
the file name.  (2)  Work with the text to categorize the documents.  (3)
Sort the file names by where I wanted the files to go.  (4)  Then use the
script to move files with the specified names to where I wanted them to go.

This is assuming unique filenames since all files are in one folder at once.

For a project I did using automated indexing for PDFs, I used A-PDF to
Excel Extractor ( http://www.a-pdf.com/to-excel/download.htm ) to put the
text of PDFs into Excel, then used Visual Basic in Excel to work the text.
Some descriptions of that project are here
http://fsulawrc.com/FACsearchengine.html and here
http://www.randtke.com/presentations/NASIG.html .  I didn't have coding
background, so was limited to tools with a short learning curve.  Your
total number of files is important in making a strategy.  I had 30,000 PDFs
to index.  If I had 500, then manually looking at each would probably have
been more efficient.
