What is drawing file is write protected?

When a drawing file is write-protected, it means that the file is locked and cannot be edited or modified without the appropriate permissions. This may occur when a user doesn't have the necessary administrator or owner rights to the file or if the file is set to read-only mode. When trying to edit a write-protected drawing file, a user may encounter an error message that prevents them from making changes or saving the file. To solve this problem, the user must obtain the necessary permissions or remove the write-protection from the file settings.
