Corrupt File Basics

• A corrupt file cannot be accessed because the information used to open the file is damaged or missing. Information can become damaged or lost by closing the program incorrectly or when transferring information in an email attachment. A file may also give signs of being corrupted and will not open if it is password protected without your knowledge.
