>    Affects Versions: 2.3

> FileUtils.sizeOfDirectory will return a negative number when the size count goes past Long.MAX_VALUE.
> Counting with a BigInteger will solve this issue. Options:
> - Change the signature of FileUtils.sizeOfDirectory() to return a BigInteger. This will obviously break BC.
> - Create a new API to return a BigInteger. What would this new API be called?
> -- sizeOfDirectoryAsBigInteger
> -- bigIntegerSizeOfDirectory
> -- largeSizeOfDirectory
> -- ...?
