Method Detail

delete

public static void delete(java.lang.String path)
                   throws java.io.IOException

Recursively delete file/directory

Throws:

java.io.IOException

remove

public static void remove(java.lang.String path)
                   throws java.io.IOException

Actually deletes a file or renames it to temp name and schedules its deletion. The latter happens if there are open references or dangling mappings to this file, in which case the actual deletion will happen when all references are closed and all mapping are cleared by the GC.

Throws:

java.io.IOException

deleteLater

public static void deleteLater(java.lang.String path)
                        throws java.io.IOException

Actually deletes a file or schedules its deletion. The latter happens if there are open references or dangling mappings to this file, in which case the file becomes inaccessible, and remains such untill all references are closed and mapping are cleared by the GC. In almost any situation you'd rather use remove().

Throws:

java.io.IOException

makeTemporary

public static void makeTemporary(java.lang.String path)

Windows-only. Advice the OS to avoid writing dirty mapped memory back to disk storage. Uses private JDK features, so it's not guaranteed to work.

makeTemporary

public static void makeTemporary(java.io.File f)
