Can you provide more specific details on the error you're experiencing? Any idea how these PDFs were created? All the files you're referring to are already in PDF format correct?

It says exactly " Adobe Reader could not open ****.pdf because it s either not a supported file type or because the file type has been damaged (for example it was sent as an email attachment and wsnt correctly decoded). It was a technical manual monitor connections, I dont know if it is encoded or encrypted or vice versa,ow can it be damaged , is there a way to repair it by another way.

Without seeing the files it's impossible to say, but Adobe Reader is one of the most forgiving applications - if it can't open a PDF file, then chances are nothing else will be able to.

The most common reason for corruption, as the dialog box indicates, is when a PDF file is sent by email and the client doesn't attach the data in the correct way. It's typically seen when using web-based email services. Once the file has been damaged it's not possible to fix it, you'll need to get a new copy from wherever it came from.
