Mark, this post might be better suited in the Technical Query Dept, rather than in Resources. Up to you.
Just found the double: General - Saving as tiff in action.
Maybe you could delete and merge.

Err? \:]
I'm not sure about that one. I don't think you can automate the destination folder as the action is working within Photoshop, not the Finder.
If you were using a Mac you could probably use Apple Script to watch the destination folder and use that to redirect the file.
One possibility would be to put in a 'Save As ..' step into the action, instead of the 'Save' step.
This would allow you to save to the original folder.
or..
Another possibility could be to include a 'Save a Copy of the Original as ..' step.
This would save a copy of the original along with the processed file to the new destination folder.
It is usually bad practice to save into the same folder as the original file to avoid the possibility of over-writing the original file.
You mention that you use the action for converting jpg to CMYK tif.
I'll guarantee that someday you will have an 'accidental' tif file which you run the action on and you will lose the original.
Maybe not a complete solution, but I hope it helps.
Cheers, Al.
