files

Clients often ask for clean urls in file names because they want to publish them in magazines so they want urls as clean as possible. H

Here is how to do this using mod_rewrite rules in htaccess:

In your .htaccess file of your drupal root folder you add following line.
For example :
All http://yourdrupal/pdf/whatever.whatever will be redirected to http://yourdrupal/sites/yourdrupal/files/private/whatever.whatever

  RewriteRule ^pdf/(.*)$ /sites/yourdrupal/files/private/$1 [L,QSA]
