It is fine to sort by filename, but I think ls.exe also will check if 
the file is direcotry/file/executable/ etc.

If I have three thousand files, ls.exe might need to process all of them 
and then start to display. What I mean is that if ls.exe sort and then 
check 100 files for directory name/file name/executable, and then 
display those 100 files, and then process the rest files to check the 
directory name/file name/executable. it can avoid the long waiting time.

I want to display all files and subdirectories in a directory, not only 
one file or one subdirectory in a directory.

Thus, I have to use ls.exe -F, or dir. But ls.exe -f won't be a solution 
if the directory has 2000 or 3000 files.
