 projectdir = 'path/to/the/folder';
 dinfo = dir(projectdir);
 dinfo( ismember({dinfo.name}, {'.', '..'}) ) = [];   %get rid of . and ..
 dinfo( [dinfo.isdir] ) = [];     %get rid of subfolders if you want to
 entries = fullfile(projectdir, {dinfo.name} );
 numfiles = length(entries);
 results = cell(numfiles, 1);
 for K = 1 : numfiles
     thisentry = entries{K};
     % process information for thisentry
     ...
     results{K} = ....
 end

ok its working, if i want to save each output as a file in a folder, then what i have to do?

[Walter Roberson]

 projectdir_in = 'path/to/the/input/folder';
 projectdir_out = 'path/to/the/output/folder';
 new_ext = '.out';
 dinfo = dir(projectdir_in);
 dinfo( ismember({dinfo.name}, {'.', '..'}) ) = [];   %get rid of . and ..
 dinfo( [dinfo.isdir] ) = [];     %get rid of subfolders if you want to
 entries = fullfile(projectdir_in, {dinfo.name} );
 numfiles = length(entries);
 for K = 1 : numfiles
     thisentry = entries{K};
     [~, basename, ext] = fileparts(thisentry);
     newentry = fullfile(projectdir_out, [basename new_ext]);
     % process information for thisentry
     ...
     write output to file named by newentry
 end

my last code is like this,

file_name='C:\Users\Thara c.s\Pictures\new for\new2OMI-Aura_L3-OMSO2e_2007m0101_v003-2018m0531t145810.he5.tif';

geotiffwrite(file_name,A,R);

after converting each data into geotiff , i have ti save it in a folder?

so i have to mention the file name including path where i supposed to save that file/geotiff?

so how will be the code for that?

and am very much impressive to our previous answer.

[Walter Roberson]

Your example file name already mentions the path to save the new file into, which is fine.

If you do not give a path when writing output, then the file will be written relative to the current directory, where-ever that happens to be.

but i have to save each file with different name to a folder? the file has to be changing in each 'k' (each entry files).

so how i do that?

file_name='C:\Users\Thara c.s\Pictures\new for\new2OMI-Aura_L3-OMSO2e_2007m0101_v003-2018m0531t145810.he5.tif';

in the above example, 'new2OMI-Aura_L3-OMSO2e_2007m0101_v003-2018m0531t145810.he5'' is to change and also keep the .tif extension.

in what II posted above you would change newentry however is appropriate . the code i posted shows how to extract the base name the new20 part but excluding the extension and then shows saving to a different folder and with a different extension . You could easily instead do something like the same folder but with 'processed_' as a prefix or whatever is appropriate . fileparts to break the input name into parts then do appropriate string manipulation then put the result together into the output file name .
