One By One

Managed to convert all my files but am painstakingly deleting the old ones now. QUITE annoying, I must say. My OCD does not permit me to do anything else before I complete it. What's worse is also discovering that quite a number of files are not converted, and even more are not fully upgraded, and some of the converted ones are corrupted. Pfft. Probably have to do another run, or worse still, change them one by one.
