Word 2007
opens the document after setting the document protection password, you can only read it, you can't
use the Office Password Recovery downloaded from the Internet, you have to pay to clear the password
. Now I will announce the removal method:
1. Change the extension .docx to .zip and compress it Package
2. Open the compressed package
3. Use Notepad to modify the settings.xml inside, delete the <w:documentProtection section
4. Repackage and change the extension back to .docx to
complete.
Other versions of doc files can be opened with word 2007, saved as docx, and then operated as usual.
