Actually there should be *none*. All that stuff should be in Win32.cpp.

Well, In Un*x, directories *do* have sizes, partially because directories
*are* a special kind of file there. Having GetSize () simply return 0 for
Dirs is fine IMHO, and it makes querying the basic Dir Entry attributes
(and the size is a basic thing) easier.

I'll remove them. They are leftovers from the days when DirEntry was a base
class for ppf_DirTreeNode instead of Directory and File. They're useless
now.

In ToPlain you assume that the path is always at least 2 chars long, which
isn't guaranteed ("/" is a valid absolute path). Fixing that.

Same method:
	/* Right now the parsing is still valid, but later versions have to 
	 * set is_parsed to false here */ 
 
	// FIX: why that? (Bjarke) 

is_parsed marks whether the part_count, part_start[] etc fields are valid.
But native paths aren't neccessarily parsed (because they're only given to
stdio anyway, which doesn't use that info). I'll take care of that.

In ToVirt:
	/* Error or undefined behavior in this case  
	if (fs == ppfFS_plain) 
	{ 
		ppInternalError ("ToVirt () called for plain URL \"%s\"", 
				 path); 
		return; 
	}*/ 
	// FIX: Why that? It works fine for dos-style paths. 

Good question. IIRC the original thought was that converting to Virt
doesn't make sense for plain paths, but that's wrong. I'll remove that code.

Also in ToVirt: you don't skip the leading '/' of the Virt'ed path. Fixing
that.


ToAbsolute () needs some fixes, together with the CWD storing in
FileGlobalData. My job.



>Why doesn't ToVirt() work for native paths? I made it work for dos-style

????
Its sole purpose is to convert native into PFile paths if neccessary.
What exactly do you mean?

It is intentional. The leading '/' isn't needed because is_absolute clearly
identifies the path as absolute anyway. Keeping the leading '/' would only
make processing code more complex/unintuitive.

I'll do.

No, I guess it's fine now. I expected the changes to be more complex.

Somehow, yes. You and Peter need to get together to make the project files
cover the *entire* libpenguinplay, i.e. PenguinFile *and* the generics
*and* PenguinSound.

Good.
