If you compare the old version to the new version:

(3.6 new version) $db->query_write("CREATE TABLE " . TABLE_PREFIX . "customfile (
userid INT UNSIGNED NOT NULL DEFAULT '0',
filedata MEDIUMTEXT NOT NULL,
dateline INT UNSIGNED NOT NULL DEFAULT '0',
filename VARCHAR(100) NOT NULL DEFAULT '',
visible SMALLINT NOT NULL DEFAULT '1',
filesize INT UNSIGNED NOT NULL DEFAULT '0',
PRIMARY KEY (userid))");

(3.5.4 old version) $db->query_write("CREATE TABLE " . TABLE_PREFIX . "customfile (
userid INT UNSIGNED NOT NULL DEFAULT '0',
filedata MEDIUMTEXT NOT NULL,
dateline INT UNSIGNED NOT NULL DEFAULT '0',
filename VARCHAR(100) NOT NULL DEFAULT '',
visible SMALLINT NOT NULL DEFAULT '1',
filesize INT UNSIGNED NOT NULL DEFAULT '0',
PRIMARY KEY (userid))");

That part of the query is exactly the same, accept for the if(!$check['customfile']) just above that part of the 3.6 version, which was just added...
