Solution found to converting .pwi files to word
I'm no computing boff, but I found a simple solution that worked for me using Word 2007.
1) Open Word 2007.
2) Then select File, Open. Make sure "All files" is selected and then select the .pwi file from it's location. Once the file is selected, THEN VERY IMPORTANTLY instead of "All files", select from the drop down menu "Recover Text from any file", and then hit Open.
3) The proceed to clean up the document from any strange or weird characters that might be present. At the end of each line, I was getting a strange character. I highlighted it, and then used the "Find" function in Word to find the same repeating character within the document, and then deleted them in one go.
Please let me know if this helped anyone else. I tried this using Word 2003 and it works also.
