Hi
Just bought a new Camera Canon Ixus 500. Seems to work fine with the WIA interface BTW.
I download the files with this renaming mask: %P%{num:3}.%{ext}
So my image IMG_0001.jpg would rename to Whatever001.jpg
An attached sound file get the number 002.wav which should be Whatever001.wav and avi files also get the filename 003.avi without the text.
This behavior I get also with a card reader.
