Wow! What a fast response.
I discard old computers, so don't have anything available that might work - everything is Win 10 and now I only have one computer with a CD/DVD drive, let alone older floppy drives. :-) (At least this program is on CD).
I have looked at the file (extension is .mcf) in notepad and most of it is gibberish, with a few discernable words so that I know that is where the data is. I have been unable to find a file converter that will work with it and not interested in purchasing the current version of Mastercook as it may not do thee trick anyhow (and they are seeking ~$100 for the program).
As for uploading the data file, I do not see that option on my interface, though I suppose I could create a link to it on my OneDrive.
