Works fine for me. Is it possible that your experience is different
from mine? Nah. Surely you must be correct that I experience pain due
to long directory names.

You have not demonstrated that it adds up to anything significant.
I'll wager it doesn't. Certainly it's far less than the time I've
spent over the last two decades writing Usenet posts.

RTFM. They're the Unicode versions of the File APIs.
http://msdn.microsoft.com/en-us/library/aa365247%28VS.85%29.aspx
Gosh, that was hard to find. First hit for "path length" on MSDN.
cmd.exe doesn't support them properly (it does for some builtins, but
it has its own path length limitations that are separate from the OS
ones), because Microsoft frankly doesn't give a damn about cmd.exe.
(If you're going to use one of their shells, they'd like it to be
Powershell.) But that's rather beside the point, which is that the
short path length limitation was corrected in Windows long ago - I
think with NT 4.0.

Did you specify it correctly, using a UNC name? I thought not.

Works just fine for me.
Here's the source:
-----
import java.io.*;
class test {
public static void main(String[] args) throws java.io.IOException {
File file = new File(args[0]);
FileInputStream fs = new FileInputStream(file);
int ch;
while ((ch = fs.read()) != -1) {
System.out.print((char)ch);
}
fs.close();
}

Junctions are a facility of NTFS, built on top of reparse points. If
you're going to complain about Windows, maybe you should learn how it
works first.

Whereas in Unix and Linux installations, all possible actions are
available in the various GUI file managers?

And now the ad hominem. Let's all watch as Zapotec loses the ability
to formulate an actual argument.

It does:
-----
C:\tmp>mklink /?
Creates a symbolic link.
MKLINK [[/D] | [/H] | [/J]] Link Target
/D Creates a directory symbolic link. Default is a file
symbolic link.
/H Creates a hard link instead of a symbolic link.
/J Creates a Directory Junction.
Link specifies the new symbolic link name.
Target specifies the path (relative or absolute) that the new
link
refers to.
-----
NTFS also supports hard links and junctions.

As indeed you can.

I agree that being able to make links and junctions from Explorer
would be useful for lazy whiners who can't be bothered to learn how
their OS works.
