Hello [~danblum] 

Thank you for your report. Would you please test with the current version 2.12.0?

The attached class does not easily demonstrate anything:
 * It's not a unit test
 * There are ZERO comments or instructions on how to use it
 * When I run as is it I get:
{quote}Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
{quote}
 * If I try to guess and pass it one argument, a folder that does not exist like c:\tmp\test where c:\tmp\ exists but c:\tmp\test does not, I get:
{quote}Exception in thread "main" java.lang.NullPointerException
at FileUtilsTest.main(FileUtilsTest.java:32)
{quote}

Please provide a useable unit test or _something_ repeatable.
TY

> Using Linux on NFS, if a file is in use and you delete it, the original file is in fact deleted but a ".nfs" file will be left in the directory until the thread or process using the file releases its handle. This prevents the directory containing from being deleted. The upshot is that if forceDelete is called on a directory and there is a file anywhere underneath it which something has open, some of the tree will not be deleted with no exception being thrown.
> I have attached a simple program which demonstrates the issue.
