Those names suggest checks to see if something is a file or directory, not existence checks. Regarding the original question: I don't think this should be changed, because the current names aren't that bad, and changing them would break a lot of code.

Not a major issue, but easily fixed.

Just to clarify: I'm not arguing for any changes to directory here, I think it should remain as is. That includes not adding in additional aliases. While I *prefer* the names in system-fileio, I don't consider it significant enough to touch a core library. As for isFile not implying an existence check: I've never had that confusion. A path can't be a file unless it exists, so to me `isFile` *does* in fact imply existence as well. On Wed, Jun 5, 2013 at 4:06 PM, Erik Hesselink wrote:
