Moving magento from subdirectory to root directory

Moving magento from sub directory to root directory require following steps:

1. Move all files from sub-directory to root directory
2. Change .htaccess file code:
   Find RewriteBase /subdirectory/ to RewriteBase /
   where subdirectory is the name of your subdirectory e.g. magento
3. Open phpMyAdmin and run these queries:
   update core_config_data set value='your new store url' where path = 'web/unsecure/base_url';
   update core_config_data set value='your new store url' where path = 'web/secure/base_url';
   

Note: your new store url must be a url i.e. http://google.com/ with trailing slash.
