[Migrations to 1.x.x version](https://github.com/webdesus/fs_extra/wiki/Migrations-to-1.x.x-version)



## Key features:



* Copy files (optionally with information about the progress).



* Copy directories recursively (optionally with information about the progress).



* Move files (optionally with information about the progress).



* Move directories recursively (optionally with information about the progress).



* A single method for create and write `String` content in file.



* A single method for open and read `String` content from file.



* Get folder size



* Get collection of directory entries

## Usage



Add this to your `Cargo.toml`:

```toml

[dependencies]

fs_extra = "1.3.0"

```

## Examples



The following example shows how to copy a directory recursively and display progress. First a source directory `./temp/dir` containing file `test1.txt` and a subdirectory `sub` is createad with `sub` itself having a file `test2.txt`. `./temp/dir` and all contents are then copied out to `./out/dir`.



```rust

use std::path::Path;

use std::{thread, time};

use std::sync::mpsc::{self, TryRecvError};



extern crate fs_extra;

use fs_extra::dir::*;

use fs_extra::error::*;



fn example_copy() -> Result<()> {



    let path_from = Path::new("./temp");

    let path_to = path_from.join("out");

    let test_folder = path_from.join("test_folder");

    let dir = test_folder.join("dir");

    let sub = dir.join("sub");

    let file1 = dir.join("file1.txt");

    let file2 = sub.join("file2.txt");



    create_all(&sub, true)?;

    create_all(&path_to, true)?;

    fs_extra::file::write_all(&file1, "content1")?;

    fs_extra::file::write_all(&file2, "content2")?;



    assert!(dir.exists());

    assert!(sub.exists());

    assert!(file1.exists());

    assert!(file2.exists());



    let mut options = CopyOptions::new();

    options.buffer_size = 1;

    let (tx, rx) = mpsc::channel();

    thread::spawn(move || {

        let handler = |process_info: TransitProcess| {

            tx.send(process_info).unwrap();

            thread::sleep(time::Duration::from_millis(500));

            fs_extra::dir::TransitProcessResult::ContinueOrAbort

        };

        copy_with_progress(&test_folder, &path_to, &options, handler).unwrap();

    });



    loop {

        match rx.try_recv() {

            Ok(process_info) => {

                println!("{} of {} bytes",

                         process_info.copied_bytes,

                         process_info.total_bytes);

            }

            Err(TryRecvError::Disconnected) => {

                println!("finished");

                break;

            }

            Err(TryRecvError::Empty) => {}

        }

    }

    Ok(())



}

fn main() {

    example_copy();

}
