maybe this will help

$files = `getFileList -fld ("c:\\yourDir\\")`;

this will list all of the files and folders in the specfied directory

I cant remember how to get the pixel info in, i know it has something to do with a thingy called iffinfo. This will allow you to read in data from .iff files.

https://www.affine.org/bmppack.html that's some info on it there I think

you can download it here

it looks quite old though you may want to look for a better version I just did a searchon google for "iffinfo" and it came up with these and loads more.

Good luck

I'll check back and see how you go with this
