zlib-ng VS uzlib

Compare zlib-ng vs uzlib and see what are their differences.

zlib-ng

zlib replacement with optimizations for "next generation" systems. (by zlib-ng)

uzlib

Radically unbloated DEFLATE/zlib/gzip compression/decompression library. Can decompress any gzip/zlib data, and offers simplified compressor which produces gzip-compatible output, while requiring much less resources (and providing less compression ratio of course). (by pfalcon)

  • Using TAR files in ESP32 with SD applications for easy multiple file transfers
    3 projects | reddit.com/r/arduino | 4 Apr 2021
    I am engineering a watch to play home videos of my children on my wrist - my Reflections project. I need an easy way to move multiple files from a Cloud based service to the watch. tar) and GZip are widely used standards to build and compress an archive of binary (for example, movies and sound files) and text (for example, JSON encoded procedural scripting command) files. Using tar I simplify my code to move one tar file instead of multiple individual files. The ESP32-targz library combines uzlib and TinyUntar to decompress and inflate tar files and works well with Arduino IDE 1.8.13, ESP32, and an SD card. This is my developer’s journal of the problems that I encountered and the work-arounds I used.
