What this really comes down to is (as others have suggested), what's 
your definition of a "junk" file? It obviously differs from the common 
approaches used by industrial junk file removal programs, because I 
doubt any of those are going to be using too much (if any) of a 
"String[] list(FilenameFilter filter)" mechanism...in whatever language 
they are written in.
