1) Wrong root handling api/params.
To stat a root directory, the "GetFileAttributes" API must be used instead of
"FindFirstFile".
To stat all files in a root dir, "C:\*" must be passed to FindFirstFile.
In all other cases, a path with [back]slash removed can be passed to
"FindFirstFile".
I know this in crazy, if you don't believe me, read CAREFULLY the FindFirstFile
docs.
P.S.:
This should make you see that the dirEntries method may have some problems...

2) Crash
The result of FindFirstFile is "enforced" in _init private method and NOT
CAUGHT in the caller public method dirEntry, and this crashes the client app.
It would be better to throw a FileException in _init and catch+rethrow it in
dirEntry.
