Testing pdf files for corruption

Thanks for the link. Unfortunately that's for version 1.51. I had already found v2.0 off archive.org, but the last version was 2.1, which was an important update because that final update allows the software to run without installing Java. All previous versions require java to run. Unfortunately archive.org never archived the final version.

Huge thank you, dalchina. That was indeed the 2.1 release! Thanks a ton for digging it up for me.

I have jpegsnoop but it seems it doesn't have a batch mode that scans all images in a directory and gives a readout on damaged files. It can scan all images in a directory, but it prints out a separate log file for each image, which makes this a no go for huge batches of files, as I would need to open every log to view the results. If there's another way using jpegsnoop, I'm not seeing it. It's great software but for error detection it seems to only be useful when scanning one image at a time. Useless when you have thousands of images you want to batch check.

Jpeginfo sounds useful but I don't know how to use it as it's command line only. The linked article gives usage instructions for Linux, but I wouldn't know how to write the Windows command to run it.

That's a new one to me. I'm just on my way out right now but I did grab it and it did open with a simple interface so it should be easy to use. Thanks again for the suggestions!
