On a flash card PDF was saved file which perfectly opened on the computer. I this file put it on a flash drive and then deleted from the computer. After a week I needed this file. When I tried to open it 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?
Maybe the PDF file was not copied properly/completely.
Thus, became corrupted.
You could try to recover the deleted file from your Computer using a data recovery software.
its occur due to you are not copied file properly or having some virus in your pdf file. instead to open in local upload to website who reads pdf file and try to open them. if file is not passowrd protect you can covert it to word or text format may be it work and you able to read your file. just search convert pdf to word and use website
Also Large PDF's may cause problems.. If the PDF file is 4 MB or larger, the Web browser may time out before it finishes downloading the file; ask the provider of the file to optimize it in Acrobat Exchange or Acrobat 4.0x. For more information on file optimization, refer to the Acrobat Online Guide.
