Issue with length function

Why does the length function never stops the iteration?
Context: Using copyfile function (matlab2018b) for copying and pasting indexed files. To note, the files are rightly copied and pasted. But the iteration never ends. Even if Idelet the files in the destination folder, it keeps pasting them.

clc
clear
SourcePath ='\\nasac-m2.isis.unige.ch\m-GAubry\GAubry\YODA\RAW_DATA\Live\S008\V1\';
Participant = 'Session_2\scans\87627';
SourceFolder = fullfile([SourcePath,Participant],'RUN_1_MIST_1_0004');
DistPath ='\\nasac-m2.isis.unige.ch\m-GAubry\GAubry\YODA\jg\prp_glm\Sub_08\';
DistFolder = fullfile(DistPath,'FunRaw_S1');
if ~exist(DistFolder)
mkdir(DistFolder)
end
for i=1:length(dir(fullfile(SourceFolder,'f*')))
copyfile(fullfile(SourceFolder,'f*'),DistFolder);
end

for i=1:length(dir(fullfile(SourceFolder,'f*')))
copyfile(fullfile(SourceFolder,'f*'),DistFolder);
end
So it would seem that the above code would try to copy the full set of files for every file in the directory that matches the condition. Perhaps the following might help
filesToCopy = dir(fullfile(SourceFolder,'f*'));
for i=1:length(filesToCopy)
copyfile(fullfile(SourceFolder,filesToCopy(i).name),DistFolder);
end

You may not see a misuse, but I'm of the opinion you should see a bad habit. Did you intend the number of elements? Then you can more reliably get that with numel. Did you really want max(size(X))? I have never seen anyone who actually wanted that.
