Change domain from temporary

If you do not delete or destroy your database, after deleting or uninstalling the plugin, The data of files will still remain.

@theronb49, if you attach a file as URL or with a full server path, the full URL will be attached and saved in the database, in such case, you may have to update path manually using some custom code after you move the site. Run the following code for once:

<?php
global $wpdb;
$files = $wpdb->get_results( "select * from {$wpdb->prefix}postmeta where meta_name = '__wpdm_files'" );
foreach ( $files as $file ) {
	$value = maybe_unserialize( $file->meta_value );
	foreach ( $value as $fileid ► $v ) {
		$value[ $fileid ] = str_replace( __OLDPATH__, __NEWPATH__, $v );
	}
	update_post_meta( $file->post_id, '__wpdm_files', $value );
}

?>

You must replace __OLDPATH__ with your old server path and __NEWPATH__ with your new server path.
