To create a new empty file in Go, use the os.Create() function.

package main

import (
    "fmt"
    "log"
    "os"
)

func main() {
    f, err := os.Create("testFile.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer f.Close()
    fmt.Println(f.Name())
}

Always remember to close the open file descriptor when you finish working with the file so that the system can reuse it:

defer f.Close()

You can then write data to this file. See how to do this in one of our previous tutorials here.
