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?

在 MATLAB Online 中打开

This shows how to

List all files in a given directory with the extension .out
Copy the file and rename the extention .txt
Delete the .out file (commented out)

% 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
