So each sub-folder contains only 1 file (a .png file)?
The code below puts the results in the structure Images.foldername
D = dir(directory_name);
D(1:2)=[];
D(~D.isdir)=[];
for i=1:length(D)
foldername=D(i).name;
pth=[directory_name pathsep foldername]);
files=dir(pth);
files(files.isdir)=[];
for j=1:length(files)
[p,n,e]=fileparts(files.name(j));
if strcmp(e,'.png')
Images.(foldername)=imread(files.name(j));
break;
end
end
end

You may be interested in the FAQ http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F which has several code examples.
OK, that's totally different. You need a function called "ClassifyFruit" that takes an image and then returns the class number 1-5 depending on whether it's an apple, banana, peach, etc. Then use sprintf() to create the folder name, and mkdir to create it if you don't have it. Then create the full filename with sprintf and use imwrite to copy the image to that folder.

See my attached code. Change the file pattern to Img_1_1_1 and it will work.
