Format error in file
Help me please. I have a problem with the file - Format error: The file is not PDF or is corrupted. What to do next, what are the usual next steps to solve such problems? can pdf recovery software which one try?There are a sufficient number of different officially-free readers that do not require installation in the system, and besides, they work smartly and the system is not littered with any adobov's helpers, for example, such as Books, Calculators, etc. If it is already impossible to open through them, then you can start up the software, I can advise Recovery Toolbox on this account https://www.oemailrecovery.com/ru/pdf_recovery.html
If only they wrote, the file was downloaded from the Internet or was stored on a hard disk / flash drive. If downloaded, the file was not downloaded, or there was an error during the download, and the file should be downloaded. If it was stored on the HDD, the file was damaged by something (it was opened by the wrong program and saved in it), the file may have been encrypted by a virus (then look for what kind of virus and how to decrypt the file specifically from this virus), bad sectors on the HDD (everything is bad )
