DiegoSoler Posted May 17, 2016 Report Share Posted May 17, 2016 We just noticed that hundreds of pdf files on our network on a certain directory we can not access. These files were scanned unto the network from an Epson scanner as pdf files. All other pdfs on the network that were not scanned we are able to open them. The ones that been scanned we get the following error message: Acrobat could not open 'filename.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded). To create an Adobe PDF document, go to the source application. Then print the document to Adobe PDF. -----------END OF ERROR MESSAGE We are running Adobe Acrobat Pro 9 in a Windows 7 environment. Please advise how we can fix these files so we can open them? Quote Link to comment Share on other sites More sharing options...
AlanHo Posted May 17, 2016 Report Share Posted May 17, 2016 Have you tried opening one of the files using a different pdf reader such as Microsoft Edge or Foxit etc. Also. though I have never had cause to use them, there are several PDF file repair tools on the internet according to Mr Google. 1 Quote Link to comment Share on other sites More sharing options...
ThoreNordli Posted May 24, 2016 Report Share Posted May 24, 2016 You've been infected with ransomware Do a full virus scan from whatever pc is connected to the NAS The files are not recoverable without paying for the unlock key. Perhaps this authoritative source will also help you. http://itknowledgeexchange.techtarget.com/itanswers/how-to-fix-format-error-not-a-pdf-or-corrupted/ 1 Quote Link to comment Share on other sites More sharing options...
ThoreNordli Posted May 24, 2016 Report Share Posted May 24, 2016 The only two ways ( without actually paying the ransom ) to recover data in case of ransomware infection is to recover from a offline backup of the files or try to restore files via a 3rd party tool. Edit What a surprise - both you and the original poster are from the same place in Latvia - why don't you pop around and give him your help in person ?

shepPettibone Posted August 20, 2018 Report Share Posted August 20, 2018 I guess there's nothing but an issue with the network exactly. If you're not sure about it, then try to open some of the files with a different tool, so you could exclude the matter of issues with the OS or network Quote Link to comment Share on other sites More sharing options...
-pops- Posted August 23, 2018 Report Share Posted August 23, 2018 I don't think there is much point in replying to a post that is more than two years old - especially as it was resolved within a few days of it being posted. Quote Link to comment Share on other sites More sharing options...
