Iterate over all files within a folder

Hi there,
since the loader's file list feature isn't available anymore, what is a (conveniant) way to load all picture files in a folder (with different filenames - not a sequence), process them and save them out with a new filename (depended on the input filename)?
Any help would be greatly appreciated!
Cheers,
Marc
