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.

The bufio package can be used to read a text file line by line.

File paths and names should be manipulated with the functions exposed by the path and filepath packages, explained here:
