In a file storage source component, a source path can be composed of regular characters and special pattern-matching characters as follows:
| 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} |

| {ab,c{de,fh}} |
