net.ontopia.utils.FileUtils was originally a class containing only generic File 
utility methods, but has now been extended with methods that contain lots of 
logic and assumptions from the test framework. I suggest a TestUtils or 
TestFileUtils class would be a better home for these methods. (Basically lines 
180 and out.)

However, Morpheus originally did it this way, and then moved the methods into 
FileUtils. PPK is the only one who knows why, and he's on holiday, so we're 
waiting for him to return so we can hear his rationale before we decide what to 
do.
