Oops! How to convert FS9 WX file type back to what it was?

[JSACKS 0]

I think I asked this about a year ago here when I screwed up something similar and thought I printed and filed the reply. So sorry for asking again. Here goes:In migrating some FS9 files from my old PC to my new PC, I meant to convert my *.FLT files into the MS Notepad format. However, I inadvertently converted all of the matching *.WX files to Notepad (!); now I want to convert the WX files back to the format they were originally in before I messed up.Can anybody tell me how to get the WX files back to their original format? I just cannot remember how I did a similar oops! and reversal last year.Many Thanks!JS
