Thanks to John Slann for his reply. I may have not been clear in my query. I have a few barely computer literate transcribers who have great difficulty understanding the processes - and, concomitantly, following instructions. "Talking" them through correctly errors is a mission. What I need to know is whether, if I have a mixture of SpeedBMD and WinBMD filenames in my batches, this causes a problem in upload.
