Why I get an error when opening the PDF file?

Question

On the USB drive was saved a PDF file, which is easy opened on the computer. I put the file on the flash drive and then deleted from the computer. After a week I needed this file. When I tried to open it with Adobe Acrobat, I get an error "There was an error opening this document. The file is damaged and could not be repaired." What is the error? How to restore a file? I use Adobe Acrobat Version 11.0.09 installed on Windows 7.

Answer 1

That files was corrupted somehow, or your USB drive is infected with malware. Try running a malware scan on the USB drive and then open Computer and right click the drive. Choose Explore, then press ALT + T, and go to View > Options > Folder Options > show hidden system files or folders. If I am correct, the file should be hidden with 100 % working condition. Alternatively, install Recuva and scan the drive for original file.
