Hello,
I have a question. I would like to change the extension of several files. I mean that in one directory a I have many files in type file1.out., file2.out ,..., file600.out.
I would like to rename these files to *.txt (I mean file1.txt, file2.txt,...., file600.txt) in this directory with one command via matlab?
Could anyone help me?

This shows how to
% Enter the directory to search
directory = 'C:\Users\name\Documents\MATLAB';
% List all .out files
fileList = dir([directory, '\*.out']);
% Loop through each .out file, copy it and give new extension: .txt
for i = 1:numel(fileList)
file = fullfile(directory, fileList(i).name);
[tempDir, tempFile] = fileparts(file);
status = copyfile(file, fullfile(tempDir, [tempFile, '.txt']))
% Delete the .out file; but don't do this until you've backed up your data!!
% delete(file)
end

Mr. Adam Danz's code is vey nice and neat. I like it. I would like to suggest, to add '\' to the secound lines of the code:-
fileList = dir([directory,'\','*.out']);

Even better would be to use the correct function for the job:
fileList = dir(fullfile(directory,'*.out'));
