deleteRecursivelyback to summary
public static boolean deleteRecursively(File root)

Delete the supplied File - for directories, recursively delete any nested directories or files as well.

Note

Like File#delete(), this method does not throw any exception but rather silently returns false in case of I/O errors. Consider using deleteRecursively(Path) for NIO-style handling of I/O errors, clearly differentiating between non-existence and failure to delete an existing file.

Parameters
root:File

the root File to delete

Returns:boolean

true if the File was successfully deleted, otherwise false

deleteRecursivelyback to summary
public static boolean deleteRecursively(Path root) throws IOException

Parameters
root:Path

the root Path to delete

Returns:boolean

true if the Path existed and was deleted, or false if it did not exist

Exceptions
IOException:
in the case of I/O errors
