I have near about 116222 .pdf files. Among them I need to find out the corrupted files.

Is there any software (free or paid) to get the files which are corrupted – or vice versa, get those that are working?

I searched a lot but could not find any. All the results were showing me software to fix broken PDFs.

What's your definition of corrupted? Unreadable by Adobe Reader? Zero pages long? ... –  Frank Schmitt Aug 22 '11 at 7:47

You could use something like Ghostscript to read them all and convert them to bitmap images which are not written to a file (e.g. on Linux redirect output to /dev/null). A script could check for return codes and error messages.
