When you use Microsoft Word to open a corrupt Word document, you will see various error messages, which may be a bit confusing to you. Therefore, here we will try to list all possible errors, sorted according to their occurring frequency. For each error, we will describe its symptom, explain its precise reason and give a sample file as well as the file fixed by our Word recovery tool DataNumen Word Repair, so that you can understand them better. Below we will use ‘filename.docx’ to express your corrupt Word document file name.
