I don't know a reason of an issue

I added a lot of information to my word document via MS Word 2010, but today something has happened and I saw: Word was unable to read the document. It may be corrupt.

See if the Open and Repair option will fix it - https://support.4it.com.au/article/error-word-was-unable-to-read-this-document-it-may-be-corrupt/

I don't use Word so had to Google for that but there is very little for Word 2010 - most refer to Word 2003 and perhaps changing the file extension as in this article may resolve - https://www.stellarinfo.com/support/kb/index.php/article/resolve-error-word-was-unable-to-read-this-document

Disregard the suggestion for that 3rd party program in that article as I cannot endorse it.

- Several "text" recovery programs.
- I have tried using word to repair and open the documents
- I have tried opening the documents in several other text browsers - ie. Notepad, wordpad etc
- I have tried using winzip, winrar and 7zip to retreive text
- I have tried changing options in word to attempt to open the document as a draft.
- I have tried to use word to "insert text" from the document
- If nothing can help you for decision problem how to restore .docx, then [Link removed by Moderator] or visit http://www.techrepublic.com/blog/10-things/10-plus-ways-to-recover-a-corrupted-word-document/

You have been reported twice for Spamming and promoting a paid for 3rd party program is classed as spamming which is why I've removed your link for that program.

Your other article may be of help to LluisaCorbi which is why I've left it, even though it does suggest possibly expensive 3rd party programs.

Spamming on this forum will get you banned.
