Display file names from current directory if more than n characters

Hi,

I want to write code that returns the filenames in my current directory, but only those filenames with more than n characters.

My code so far:

directory = dir('*.*'); % specifiy files, leave out folders
% remove the two '.' and '..' folders at the top
if length(directory) >= 3
	directory = directory(3:end);
end

But how do I select only those filenames with more than n characters? I thought about setting up a logical vector, but I don't know how to do that. Does anybody have any suggestions?

Many thanks,

Dobs

"But how do I select only those filenames with more than n characters?"

Is that actually the goal, or is this really just your attempt to remove the dot directory names?:

Note that the dot directories are not guaranteed to be the first and second names returned, so your code already has a bug in it:

Yes, selecting the filenames with more than n characters is actually the goal because it's for an assignment.

n = 5;
P = 'absolute or relative path to where the files are saved';
S = dir(fullfile(P,'*.*'));
C = {S(~[S.isdir]).name}; % comma-separated lists
X = cellfun(@numel,C)>n;
C = C(X)
