How do you get full paths of all files in a directory in Go?

I am using Go to iterate over all the files in a directory. This is how I am doing it:

package main

import (
	"fmt"
	"io/ioutil"
)

func main() {
	printFiles(".")
}

func printFiles(dir string) {
	fileInfos, err := ioutil.ReadDir(dir)
	if err != nil {
		fmt.Println("Error in accessing directory:", err)
	}

	for _, file := range fileInfos {
		fmt.Printf("%T: %+v\n", file, file)
	}
}

When I run this code, this is the output I get:

*os.fileStat: &{name:main.go sys:{FileAttributes:32 CreationTime:{LowDateTime:2993982878 HighDateTime:30613689} LastAccessTime:{LowDateTime:2993982878 HighDateTime:30613689} LastWriteTime:{LowDateTime:4004986069 HighDateTime:30613714} FileSizeHigh:0 FileSizeLow:320} pipe:false Mutex:{state:0 sema:0} path:C:\Users\Prakhar.Mishra\go\src\mistdatafilter\main.go vol:0 idxhi:0 idxlo:0}

I can see a property named path, but I can't access it (due to small case initial, I suppose?). Can anyone please tell me how to get full file path of all the files in a given folder?

If you want to see a full path, you should start with a full path. . is a relative path.

You can get the working path with os.Getwd

path, err := os.Getwd()
// handle err
printFiles(path)

The rest is simply appending the file name to the directory path. You should use the path/filepath package for that:

for _, file := range fileInfos {
    fmt.Println(filepath.Join(path, file.Name())
}

You can also use the filepath.Abs method from the standard library

import (
    "fmt"
    "os"
    "path/filepath"
)

files, _ = os.ReadDir(dir)
path, _ := filepath.Abs(dir)
for _, file := range files {
    fmt.Println(filepath.Join(path, file.Name())
}

You already have the directory path simply append them to the file name something like:

files, err := ioutil.ReadDir(dirPath)
check(err)

for _, file := range files {
    fmt.Println(dirPath + file.Name())
}
