Multisite are not creating folders for the subsites

Question

Sorry, tried looking around for an answer for this but couldn't find any existing threads. I set up multisite locally, I'm using Xampp, and for some odd reason there are no directories being created by the subsites. I can see the sites being created in the network admin but can't access the dashboard because the subdirectory doesn't exist, error 403. It's setup to use subdirectories, not subdomains. I'm not sure if this helps but this is what I got from the apache error log. Keep in mind that there's no invalid character on the site names, no special characters or even spaces just alpha chars.

.htaccess file (from pastebin in comments)

RewriteEngine On
RewriteBase /multisite/wordpress/
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) A:/MyProjects/JunRoot/Multisite/wordpress/$2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ A:/MyProjects/JunRoot/Multisite/wordpress/$2 [L]
RewriteRule . index.php [L]

You can find the various recommended .htaccess configurations on the Codex's .htaccess page. Here's the one for subdirectory Multisite later than WordPress 3.5:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

I note that in your .htaccess file, you're trying to Rewrite things to a file location (A:/...) rather than to a URL. I think this is probably the error you're running into.
