I had a similar issue and it all came down to:
1) if you mean "running on windows" OS you need to include, and start from the drive directory (where server is installed) in $dir to scan.
2) Windows might be picky about separators, compare your $dir with Wordpress ABSPATH and try to use PHP constant DIRECTORY_SEPARATOR instead of your own '/' separators.
3) And I asume you working with paths, not urls (http://localhost/wordpress/...plugin/dir/). This is working for me on Windows 7, running Uniserver (LAMP):
$rootfolder = 'startfolder';
$dir = plugin_dir_path(dirname( __FILE__ )).DIRECTORY_SEPARATOR.$rootfolder;
$files = array_slice(scandir($dir), 2);
However, you need to cut down the path end begin in the install dir with ABSPATH or something. But I recommend to test where your filescript is, like plugins folder, to not consume a huge stall on errors while working with this kind of stuff.
Hint!
The PHP docs about scandir has a lot off contributed functions about reading, retriving, scanning functions and issues. Take a look at: http://php.net/manual/en/function.scandir.php
Important!
Do not start messing with windows folder access, and if you do, take a RAW copy of whole www directory first, otherwise exported Worpdress installs could get messy on a Apache server live.
Remember, did you manage to install a new plugin from the Wordpress
admin, you propably dont have a folder access issue.
Hop this helps!
