All Works files have a header that identifies the document type, which in turn indicates to the operating system the format of the data in the document. Corrupt documents can experience damage to the header, which may be the reason why you cannot open your Works WP document.
This method can only be used by converting the file into .txt format, for editing in Notepad or a similar plain text editor.
Open a Command Prompt by going to Start > Run and entering cmd.
Type the following, where [name] refers to the filename of your damaged Works document.
Copy con+[name].wps [name].txt
Hit Enter – you will then be greeted by a CON prompt. Tap Spacebar 12 times to continue, then press F6 and Enter. Finally, type and enter the command exit, and the box will close.
In Works, go to File > Open and in the Files of Type box select Text (.txt). Select the newly created text file, and click Open.
The text file version of the will display a collection of unusual characters at the header and footer of the document. You will need to check that your document is correctly formatted, and that the data is intact before saving again, this time as Works WP format.
