folders = dir('*') ; 
N = length(folders) ; 
filenames = cell([],1) ;
n = 0 ; 
for i = 2:N
    if isfolder(folders(i).name)
        n = n+1 ; 
        filenames(n) = dir([folders(i).name,filesep,'*.txt']) ;  
    end
end

Now you have all the filenames, you can get what you want using that.

c = ismember({filename(1).name},{filenames(2).name})

ismember will give logical array.how to use it to find duplicate files.?because one file might be present more than one time..then how to identify which file is present more than one time using ismember?
