- io.vertx.mutiny.core.file.FileSystem

```
public class FileSystem
extends Object
```
Contains a broad set of operations for manipulating files on the file system.
A (potential) blocking and non blocking version of each operation is provided.
The non blocking versions take a handler which is called when the operation completes or an error occurs.
The blocking versions are named xxxBlocking and return the results, or throw exceptions directly. In many cases, depending on the operating system and file system some of the potentially blocking operations can return quickly, which is why we provide them, but it's highly recommended that you test how long they take to return in your particular application before using them on an event loop.
Please consult the documentation for more information on file system support.
NOTE: This class has been automatically generated from the original non Mutiny-ified interface using Vert.x codegen.

                                         String to)
```
    Copy a file from the path from to path to, asynchronously.
    The copy will fail if the destination already exists.
    Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.
    
    Parameters:
    
    from - the path to copy from
    
    to - the path to copy to
    
    Returns:
    
    the uni firing the result of the operation when completed, or a failure if the operation failed.
  - copyAndAwait
```
public Void copyAndAwait(String from,
                         String to)
```
    Blocking variant of copy(String,String).
    This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).
    
    Parameters:
    
    from - the path to copy from
    
    to - the path to copy to
    
    Returns:

                                String to)
```
    Variant of copy(String,String) that ignores the result of the operation.
    This method subscribes on the result of copy(String,String), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from copy(String,String) but you don't need to compose it with other operations.
    
    Parameters:
    
    from - the path to copy from
    
    to - the path to copy to
    
    Returns:

  - createTempFileAndAwait
```
public String createTempFileAndAwait(String dir,
                                     String prefix,
                                     String suffix,
                                     String perms)
```
    Blocking variant of createTempFile(String,String,String,String).
    This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).
    
    Parameters:
    
    dir - the path to directory in which to create the directory
    
    prefix - the prefix string to be used in generating the directory's name; may be null
    
    suffix - the suffix string to be used in generating the file's name; may be null, in which case ".tmp" is used
    
    perms - the permissions string
    
    Returns:
    
    the String instance produced by the operation.
  - createTempFileAndForget
```
public FileSystem createTempFileAndForget(String dir,
                                          String prefix,
                                          String suffix,
                                          String perms)
```
    Variant of createTempFile(String,String,String,String) that ignores the result of the operation.
    This method subscribes on the result of createTempFile(String,String,String,String), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from createTempFile(String,String,String,String) but you don't need to compose it with other operations.
    
    Parameters:
    
    dir - the path to directory in which to create the directory
    
    prefix - the prefix string to be used in generating the directory's name; may be null
    
    suffix - the suffix string to be used in generating the file's name; may be null, in which case ".tmp" is used
    
    perms - the permissions string
    
    Returns:
    
    the instance of FileSystem to chain method calls.
  - createTempFileBlocking
```
public String createTempFileBlocking(String dir,
                                     String prefix,
                                     String suffix,
                                     String perms)
```
    Parameters:
    
    dir -
    
    prefix -
    
    suffix -
    
    perms -
    
    Returns:
  - newInstance
```
