Batch rename pdf based on data from Title of pdf file itself?

Question

Command line

As a result of recovering pdf files after a crash, more than 100,000 pdf files with names consisting of numbers appeared on the disk.
pdfinfo from the xpdf package gives the following information about such files
pdfinfo 121324235245.pdf

Title can be used in the file name.
Please tell me how the batch file for Windows 7 will look like to rename a pdf file if the Title is full and leave it as it is if the Title is empty?

Answer 1

Hmm... well let's start simple :)

pdfinfo.exe "C:\file.pdf" | findstr "Title"

Will give us a string with a name.
