Preethi, try this:

% Specify the top level folder.
topLevelFolder = 'C:\Users\Mark\Pictures';
% Add this folder and all of its subfolders to the search path.
addpath(genpath(topLevelFolder));
% Define the base file name of the file you are looking for.
baseFileName = 'anagrams.png';
% Display it.  It will find it on the search path if it's there.
imshow(baseFileName);

I have used system() and check for the path in the output, got the result but process was tedious. What you have suggested is very simple, thank you

Note: it is not guaranteed that "." and ".." will be the first two entries in the directory list. The order is arbitrary. You should be testing against the names, not against the positions.
