ADeletes the given directory, which must be empty, never symlinks.
Throws:

<00>+ for wrong file type (symlink to directory)
<00># for wrong file type (regular file)
<00> if directory does not exist
<00> if directory is not empty
<00>. if we can't open or write to parent directory

Notes: calls rmdir<00>

PDeletes the given directory recursively. Does not follow symbolic
 links. Tries 
<00>/ first before attemtping a recursive
 deletion.

(On directory contents this behaves like 
<00>
1
 and thus will ignore any file type that is not 
<00>
,
 
<00>
 or 
<00>
.

<02>Deletes a file, directory or symlink.
 In case of directory, performs recursive deletion. In case of
 a symlink, the symlink file is deleted.
 Any other file type is ignored.

nRename a given file with the provided filename. Destination and source
 must be on the same device, otherwise

dMove a file. This also works across devices by copy-delete fallback.
 And also works on directories.
CDoes not follow symbolic links, but renames the symbolic link file.
Safety/reliability concerns:

<00> mode is not atomic-copy-delete fallback is inherently non-atomic
since this function calls

 and 
<00>
 as a fallback
      to 
<00>
, file types that are not
