How to Compress Folder in Golang - Backup Files Software From Scratch Written in Golang Tutorial #3
In this tutorial series #3, we have learned how to compress the entire folder and its files using the Golang programming language and it's very easy to do this with Go. I use the tar.gz or gzip file compression in Go.
