Well, something is wrong here, you should have an index on JobId as follows:
+-------+------------+------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+
| Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation |
Cardinality | Sub_part | Packed | Null | Index_type | Comment |
+-------+------------+------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+
| File | 0 | PRIMARY | 1 | FileId | A |
1309549 | NULL | NULL | | BTREE | |
| File | 1 | FilenameId | 1 | FilenameId | A |
218258 | NULL | NULL | | BTREE | |
| File | 1 | FilenameId | 2 | PathId | A |
654774 | NULL | NULL | | BTREE | |
| File | 1 | JobId | 1 | JobId | A
| 119 | NULL | NULL | | BTREE | |
+-------+------------+------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+
