Unzipping code in a loop within another loop?

Quite a beginner in MATLAB so finding it a little difficult to construct the code for this... I currently have zipped files within folders within folders, which I need to unzip before manipulating the data further. I believe I need some form of a loop within a loop for this to work? But have no idea how to script this! Any help would be appreciated!

Since you are a beginner, I will assume you are running R2017a or later.

projectdir = 'TopLevelFolder';    %can be fully qualified

%this next requires R2017a or later
dinfo = dir( fullfile( projectdir, '**', '*.zip') );   %find all .zip underneath the projectdir.

%then
for K = 1 : length(dinfo)
   unzip( dinfo(K).name, dinfo(K).folder );  %still needs R2017a or later
end

Hi Walter, so would this not work with R2016b?

It works well under R2016b. I assume Walter means the '**' key in dir, but this was support in R2016b as well as the field 'folder'. If you are in doubt, George, simply try to run the code: If it runs, it runs.
