How to extract contents of multiple tar files in a loop?

Hello Everyone,

I have multiple .tar.gz files that I'd like to extract contentes of them. For one file I use

path = 'C:\Users\data\example.tar.gz';
gunzip(path, 'example');
untar('example/example.tar','example');

However, I have many of these files (each one has a specific name) and I don't want to go through all of them one by one. I tried to use the following code in a for loop but no luck so far since these are not folders but .tar.gz files

D = 'C:\Users\data\';
S1 = dir(fullfile(D,'*'))
N1 = setdiff({S1([S1.isdir]).name},{'.','..'}) 

Any idea how I can do that?

Do you mean something like this?

input_folder = 'C:\Users\data\';

file_struct = dir([input_folder '/**/*.tar.gz']);
file_names = {file_struct.name};
files = fullfile({file_struct.folder},file_names);

for f = 1:numel(files)
    file = files{f};
    untar(file);
end

Thank you so much! This is what exactly I was looking for.

Do you know how I can put all these untar folders in a new created folder? I'd like to creat a new folder, called ExtractedData, that contains all data. Ive created the new folder as follow but wasn't able to put the extracted data directly on it. Thanks!

destinationdirectory = 'C:\Users\ExtractedData';
mkdir(destinationdirectory);

Look at the help for untar:

untar(tarfilename,outputfolder)

so you would have this:

untar(file,destinationdirectory);
