filename = 'Target.csv';

if exist(filename, 'file')
    fprintf('Okay, exist thinks it is there\n');
else
    fprintf('Exist does not think it is there\n');
end

[fid, message] = fopen(filename, 'r')
if fid < 0
    fprintf('fopen fails saying "%s"\n', message);
else
    fprintf('fopen works!\n');
    fclose(fid);
end

[folder, basename, ext] = fileparts(filename);

dinfo = dir(fullfile(folder, [basename, '.*']));
if isempty(dinfo)
    fprintf('dir does not find any files with the same base name and any extension\n');
else
    fprintf('dir finds some files with the same basename. Available files are:\n');
    celldisp({dinfo.name});
end

dinfo = dir(fullfile(folder, ['*' ext]));
if isempty(dinfo)
    fprintf('dir does not find any files with any name and the same extension\n');
else
    fprintf('dir finds some files with the same extension. Available files are:\n');
    celldisp({dinfo.name});
end
