prompt1 = '\nplease enter the starting serial number\n';
first_SN = input(prompt1);
prompt2 = '\nplease enter the ending serial number\n';
ending_SN = input(prompt2);
prompt3 = '\nplease enter the step size\n';
step = input(prompt3);
temp_directory = dir;
size(temp_directory)
class(first_SN)
b = 1;
a=first_SN;
while a <= ending_SN %%%builds list of serial numbers
SN{b}= num2str(a);
b = b+1;
a = a+step;
end
for c = 3:size(temp_directory)
temp_directory(c).name
isempty(strfind(SN, temp_directory(c).name)) % at this point is just copying the files from the temp dir
if isempty(strfind(SN, temp_directory(c).name)) ~= 1 % how my i have it just select the range of SN numbers
serial_number_folders(c).name = temp_directory(c).name;
end
end
end

You need to parse your filename to get the serial number (string) into a number (double). Then you can use an if inside your for loop to skip numbers outside the range
for k = 1 : numFiles
thisFileName =
serialNumber = ParseFilename(thisFileName);
if serialNumber < minSerialNumber || serialNumber > maxSerialNumber
continue; % Skip this file.
end
% else process the file.
end

Tell me what a typical file name is and tell me what characters in the filename represent the serial number. Or is the serial number inside the file, not a part of it's file name?
