Hi there wamuggers

I have a folder containing an image sequence saved from FCP in a folder.

Projectname 0001.png
Projectname 0002.png

Etc to 2887

What I want to do is separate the odd numbered files from the even no. of
files (I'm converting interlaced alternating field 3d into red blue 3d)

Does anybody know how to do this separation process?

Thanks in advance

john
