File Operations in Go

Internal

• Go Code Examples
• Go Package os
• Go Package ioutil
• Go Package path

Overview

The os package provides practical file access functions. Basic file read and write, by reading or writing the entire file into and from memory, is also provided by the ioutil package, but its ioutil.ReadFile and ioutil.WriteFile are deprecated since Go 1.16.

File paths and names should be manipulated with the functions exposed by the path and path/filepath packages.
