Field Summary

Modifier and Type	Field and Description

ALLOW_INSECURE	back to summary
public static final RecursiveDeleteOption ALLOW_INSECURE Specifies that the recursive delete should not throw an exception when it can't be guaranteed that it can be done securely, without vulnerability to race conditions (i.e. when the file system does not support `SecureDirectoryStream`). Warning On a file system that supports symbolic links, it is possible for an insecure recursive delete to delete files and directories that are outside the directory being deleted. This can happen if, after checking that a file is a directory (and not a symbolic link), that directory is deleted and replaced by a symbolic link to an outside directory before the call that opens the directory to read its entries. File systems that support `SecureDirectoryStream` do not have this vulnerability.
