XnView Software

if I want to rename the output files with the # placeholder it only generates one image with the number 0. I use this in a batch file like

c:\programme\xnview\nconvert -npcd 2 -q 70 -size 256x256+0 -opthuff -rmeta -ctype grey -corder inter -out jpeg -o "##.jpg" -ratio -rtype lanczos -resize 800 800 ...

In a batch file under Windows XP I use

for /R %%I in (*.*) do c:\programme\xnview\nconvert -npcd 2 -q 70 -size 256x256+0 -opthuff -rmeta -ctype grey -corder inter -out jpeg -o "J:\bild\%%~nI.jpg" -ratio -rtype lanczos -resize 800 800 "%%I"

to convert all files including subdirectories
