public FileUtils()
public static void deleteDirectory(File directory) throws IOException
directory - directory to deleteIOException - in case deletion is unsuccessfulpublic static void cleanDirectory(File directory) throws IOException
directory - directory to cleanIOException - in case cleaning is unsuccessfulpublic static void forceDelete(File file) throws IOException
The difference between File.delete() and this method are:
file - file or directory to delete, must not be nullNullPointerException - if the directory is nullFileNotFoundException - if the file was not foundIOException - in case deletion is unsuccessfulpublic static void forceDeleteOnExit(File file) throws IOException
file - file or directory to delete, must not be nullNullPointerException - if the file is nullIOException - in case deletion is unsuccessfulpublic static boolean isSymlink(File file) throws IOException
Will not return true if there is a Symbolic Link anywhere in the path, only if the specific file is.
Note: the current implementation always returns false if
the system is detected as Windows using
File.separatorChar == '\\'
