I have a directory full of different files. The function I have will fopen and fread the content and process it to create other files. My function takes in parameter (parameter being the title of the file), but I would like to make the function run through the directory and read only the .raw files in that folder. Any help?

Just get the function to work on the selected files in the folder to begin with:

i.e.

    fileNames = dir('*.raw');     % structure
    fileNames = {fileNames.name}; % actual names extracted to cell array

But for the above method to be applicable the folder has to be in the current directory.

I need help on how to do the above requested task when the folder is not in the current directory and i dont want to change the directory.

for k = 1:numel(S)
    F = fullfile(D,S(k).name);
    yourFunction(F)
