If you pass a quoted directory name to dir(), including any relevant drive letters, then dir() will return information for that directory (or give an error about not being able to get the information.)

However, the 'name' field of the structure that is returned by dir() never includes any part of the name of the directory that was queried: you have to add the directory name in yourself if you want it.

For example,

fileinfo = dir('E:\MyFiles\*.jpg')

then fileinfo.name will never include the E:\MyFiles part, just the E73rk.jpg or whatever the file name is within the directory.

targetdir = 'E:\MyFiles';
targetfiles = '*.jpg';
fileinfo = dir(fullfile(targetdir, targetfiles));
for K = 1 : length(fileinfo)
  thisfilename = fullfile(targetdir, fileinfo(K).name);
  ...
end
