Why can't I see my saved recipes in Windows Explorer?
When PL Pilot saves recipe files, it does not save them with a name such as the description you may have given when in "recipe management". Instead it just increments the file extension for every new recipe saved. Furthermore, it does not always save the recipes using names relating to the screen you happen to be in - if you were saving a recipe in the "Total Recipe" screen for example it would be saved as Recipe7.Rxx where xx is the incremented number, R00 being the "default" recipe and R01 would be your first saved recipe.
If you have a number of saved recipes and are not sure which one is which, you can right click on a recipe when in Windows Explorer and open the file with Word Pad or a similar application. You will be able to see the description you gave the recipe at the start of the displayed data.
