Prefix and suffix in same folder

[mfeske]

Hello,
I use xnview and i will work recursive in a folder.
the new pictures should have a prefix and a suffix.
i I use d:\picture\pre_%_su without underfolder option i get the new picture with prefix and suffixe, but in the folder d:\picture\pre_%_su.
if i use with underfolder option i get the new pictures in d:\picture\pre_%_su with correct folder structur but without suffix and prefix.

What can be the Problem?

Later I want to make from one folder with underfolder all pictures with watermark and in three dimensions, what can i do that xnview not get the ready pictures for the second and third step?

greetings micha
