Problem with extract PDFs from huge files.

Hello Unix experts,

we have a problem Smilie
We have some binary files ~25GB. In this files are many (millions) PDF files included.
How we can extract them from such huge files? In small files I got it with the command:
Code:
awk -v FS="(%PDF-1.4|%%EOF)" '{print $2}' FILE > OUTPUTDIR

so the PDF file begins with PDF-1.? and ends with %%EOF
but it don't works on such big files. So we need another way to extract them.

Thanks in advance!
