Description

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
  • ...?
