Compress and Decompress File In Mule 4

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

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.
• Gzip can save more disk space than ZIP compression applications.
• Both Gzip and ZIP use the DEFLATE compression algorithm

We will create a sample project in anypoint studio to compress the file and write to folder as soon as the file is compressed it will be read from a folder and uncompressed the same file back to original size into another folder

TestData:

Create a sample pdf file to read

Drag and drop the http listener and configure the same to trigger the flow
