Thanks Greg. I realise I actually did not setup the macro properly. In the mean time I came across a VB script for word files that I could rename a few of my files with. With that and finding duplicate files with a utility I completed the job with all my *.doc files. I still have many thousands if docx, ppt, pptx files to deal with. I'll use your guide to setup your macros and try. Thanks for helping out.
