How to run a for loop with a string as loop index?

I want to run a loop for opening all files in a directory, and accessing each file's name.Here's my code:

 AllFiles=dir('');
TotalFiles=size(AllFiles,1)-2;  %skiping first two entries are '.' and '..' 
FolderPath=AllFiles(1).folder; %same folder for all files
for i= AllFiles(3).name : AllFiles(TotalFiles).name
    FilePath=strcat(FolderPath,'/',i);

end

Do NOT do this:

TotalFiles=size(AllFiles,1)-2;  %skiping first two entries are '.' and '..'

This is fragile code that incorrectly assumes that the first two elements of the structure refer to the folders '.' and '..'. This is NOT documented, depends on the OS, and is not necessarily correct.

A more reliable way to is to test the names explicitly and remove them using indexing:

S = dir('');
X = ismember({S.name},{'.','..'})
S = S(~X);

Also you should use fullfile rather than string concatenation:

S = dir('.');
S = S(~ismember({S.name},{'.','..'}));
for k = 1:numel(S)
    F = fullfile(S(k).folder,S(k).name);
    ...
end

Based on the examples in the MATLAB documentation:

I just to explain it further for MOMIL IJAZ

It is always better to specify what kind of files you want to load in the folder.

AllFiles=dir('*.mat');

which it does not done in original script.
