Description

Hello. Here's what happens (when a user doesn't have admin privileges in windows 7):

c:\Program Files (x86)\NetBeans 6.9.1>irb --simple-prompt

File.writable?('.')
=> true
File.writable?('./uninstall.exe')
=> true
File.open('./uninstall.exe', 'wb')
Errno::EACCES: Permission denied - ./uninstall.exe
from (irb):4:in initialize' from (irb):4:in open'
from (irb):4

So I think writable was returning true in error here.
Cheers!

Thank you, Roger.

Currently we don't support NTFS ACLs.
This is the one of lacks of the important features, I think.
We shall support it someday.
The problem is who/when/how does it...

Use win32-file if you want a working File.writable? on Windows.
