+# qbittorrent-clener
+
+Super basic PHP script which gets all torrents + files associated.    
+It will then list the untracked files (usually extracted files) and ask if you wish to delete them.
+
+```
+$ php clean.php "<qbittorrent host>" "<username>" "<password>" "<download path>"
+```
+    
+For example:    
+```
+$ php clean.php "http://127.0.0.1:8080" "bob" "super_secure_password" "/home/bob/Downloads"
+```
