# ETL: Pattern Matching in Source Paths

> Use glob pattern matching in file storage source component paths to select multiple files. Supports wildcards and pattern-based file selection.

| **Pattern**         | **Description**                                                                                                                                       |
| :------------------ | :---------------------------------------------------------------------------------------------------------------------------------------------------- |
| **?**               | Matches any single character.                                                                                                                         |
| **\***              | Matches zero or more characters.                                                                                                                      |
| **\[abc]**          | Matches a single character from character set `{a,b,c}`.                                                                                              |
| **\[a-b]**          | Matches a single character from the character range `{a...b}`. Note that character a must be lexicographically less than or equal to character b.     |
| **\[^a]**           | Matches a single character that is not from character set or range `{a}`. Note that the ^ character must occur immediately after the opening bracket. |
| **\c**              | Removes (escapes) any special meaning of character c.                                                                                                 |
| **`{ab,cd}`**       | Matches a string from the string set `{ab, cd}`                                                                                                       |
| **`{ab,c{de,fh}}`** | Matches a string from the string set `{ab, cde, cfh}`                                                                                                 |
