I tried

https://stackoverflow.com/questions/113 ... ip-on-zlib.

It works on windows platform.

zipOpen just hangs on esp32 platform.

Unzip using zlib and minzip is working for me to Esp32 platform.

Any idea?
Sorry. Didn't look into that after.

So, zlib and minzip are working fine for ESP32 which might be helpful for others.

Thanks for update regarding same.

Kind of late to the party, I'm sorry. I just saw this post today. See my developer journal article at https://www.reddit.com/r/arduino/commen ... tions_for/ -Frank

Hie,
I'm also stuck at similar problem. In my case i have to download an archive file(don't matter anything is file zip or tar.gz depends on what esp support). downloading file from server is not issue. how to unzip it? that archive support to have more than 2 files in it.
I'm using esp-idf v4.2.

Hello,

You can use zlib and minzip libraries as per your requirements which can be feasible to do it.

Hello @Ajit,

We have used those libraries before few years ago and also ESP32 IDF was tool much older like 3.0 version. But, You can take reference zlip libraries and can verify with compilation from your end.
