Delete files with specific sizes

Hello everyone,

I want to ask a question.

I have a directory of flight data files and I want to delete some files that have less size than, for example 500 kb.

Is there any way to do it in loop?

Thanks

Get the directory files

files = dir('your directory');

Apply loop and delete with your condition

for ii = 1:length(files)
    if files(ii).bytes<500000   % 500kb
        delete(fullfile(files(ii).folder, files(ii).name)
    end
end

Do I have to insert the files name?

You may want to change the if to:

 if files(ii).bytes<500000 & ~files(ii).isdir   % 500kb

to avoid the loop erroring if there's any subfolder.

You don't even need the loop:

files = dir('your directory');
todelete = [files.bytes] < 500e3 & ~[files.isdir];
deletelist = fullfile({files(todelete).folder}, {files(todelete).name});
delete(deletelist{:});

actually i'm a bit confused how to use these. (i'm new to matlab).

can you please give me the example?

let's say my folder is "Project" in D drive, and the folder has about 600 files.

You can learn/refer MATLAB fundamentals to apply solution to your problem. MATLAB provides very rich documentation clearly.
