How to access .csv files in a .tar.gz file?

Greeting!

I have a bunch of *.tar.gz files, say 100 (example1-example 100). In each of them I have more than 1000 .csv file that I would like to extract data from these .csv files.

I am using following code to access the .csv files.

url = 'C:\Users\....\Test\example1.tar.gz';
files = gunzip(url, 'example1')

what I get is

files = 1*1 cell array
        {'example1\example1.tar'}

However it doesn't make any "example1.tar" in the "C:\Users\....\Test\" folder. Then I'm using the following line to get the . cvs files

filenames = untar('example1/example.tar','example1')        

and I get

filenames = 1*953 cell array
{example1\example_1\}    {example1\example_1\config1\}    {example1\example_1\config1\imag.csv}    {example1\example_1\config1\real.csv}.....
    {example1\example_1\config50\}   {example1\example_1\config50\imag.csv}   {example1\example_1\config50\real.csv}  ......

I would like to have access the data on imag.csv and real.csv for all configs. How should I do that?

Should I use something like

 load(fullfile('..', 'example1', 'example_1', 'config1', 'imag.csv'))

Thank you for any help you can provide, I'm really stuck on this.

I do not know if the following will work for .gz but you could try it: https://www.mathworks.com/matlabcentral/fileexchange/77257-zipfile

Thanks for your feedback. I've checked these links out but couldn't help to solve my problem. Thanks though!

You can call a function recursively on the folder, and process the files which match your requirement. See https://www.mathworks.com/matlabcentral/answers/92761-how-can-i-recursively-process-files-in-subdirectories-using-matlab for detailed explanation.
