Being an administrator and running with elevated permissions are not the same thing

More about these "magic dirs", can be found here under junctions https://msdn.microsoft.com/en-us/library/windows/desktop/aa365006(v=vs.85).aspx and here https://msdn.microsoft.com/en-us/library/windows/desktop/aa365503(v=vs.85).aspx

It seems file::find sees them as a normal direcory, and doesnt have the permissions to "reparse" them.

Thanks all for responses, and I have more perl reading than time, which will suit my dental cleaning appointment just fine tomorrow. I've skimmed what was posted mod one and taken what I thought most relevant for scripts moving forward. Right now, I'm drawing cpan errors with my strawberry perl install. I'm putting this output between readmore tags again along with the new source listing the way windows sees it.

Read more... (5 kB)

The way I see it is that I was doing alright. I believe to have cleared the cpan dependencies, but see complaints that look like things a C compiler says. Perl on windows 10 is such an odd platypus that I can't think of where C libraries are and how to remediate that.

Update

Source listing and errors:

Wow

Im not sure you realize that the "wanted" sub gets passed directories too. i often have a return unless (-f $file); in there.

another thing the wanted sub can do is signal to prune the tree. $File::Find::prune = 1 is a signal to File::Find not to follow a directory. You want to prune junction points.

        # this test for directory
        $stat->{mode} & S_IFDIR ? print "Directory\n" : print "File\n"
+;
        # is the same as this one
        $stat->{attribs} & FILE_ATTRIBUTE_DIRECTORY ? print "Directory
+\n" : print "File\n";
my $isjunction= <.. some code to see if its a junction ..> ; 
if ($isjunction){ 
    $File::Find::prune = 1
    return; 
}

now you may even be able to contrive a test <.. some code to see if its a junction ..> that does not require "use Win32::LongPath", i dont know what it is now. Otherwise i think you are stuck trying to install that module. , sorry
