for l = 1:8
fid=fopen(sprintf('E:\\ReliabilityAll\\alpha\\sub%d.txt',l));
StartLine=3;
for k=1:StartLine-1
fgetl(fid); % read and dump
end
Fline=fgetl(fid); % this is the 3rd line

You might also use a direct loop on the result of using the 'dir' command, if the '*' placeholder is sufficient for your search. Take care to use the transpose operator ' on the result of dir, because you need a row vector of results to for-loop.
sDir = 'C:\Users\Khan\Documents\MATLAB';
for sctFile = dir(fullfile(sDir, 'sub*.txt'))'
fh = fopen(fullfile(sDir, sctFile.name));
% here goes your code
% ...
fclose(fh);
end
Or just dir on the directory, and filter the file names within the loop..
