getFileList ignore subdirectories

[coalbee]

I am writing a command prompt batch file that refers to several imageJ macro and batch commands.  I begin with an "Images" folder, containing only images.  After the first step, however, a folder called "warps" becomes a subdirectory within "Images."  Now when the subsequent imageJ batch/macro files run, the getFileList(dir) command(within the batches/macros)  includes this subdirectory("warps").  I only want to work with the images though.  Is there a way to screen the directory for only images and ignore subfolders?

Thanks!
