In this tutorial we will demonstrate how can we compress and decompress the file in mule 4, In Mule 4 compresses and decompresses files for each of the available formats.

Below operations are supported for compress Module

  • Archive: Compresses all the given entries into a new file in the configured format
  • Compress: Compresses a given content using the configured format, ZIP or GZIP.
  • Decompress: Decompresses a single entry of compressed content which is assumed to be in an specific format (ZIP or GZIP).
  • Extract: Decompresses a given content that represent an archive in a compression format.

ZIP Compressor vs GZIP Compressor:

  • ZIP is more popular on Windows operating systems.
  • Gzip is the standard file compression for Unix and Linux systems.
  • Gzip is faster than ZIP while compressing and decompressing.
  • ZIP is an archiving and compression tool, all in one, while Gzip needs the help of Tar command to archive files.
