wildcard

Wildcards are special characters or strings that can represent one or more characters in a search query, file name, or other string of text. The importance of wildcards lies in their ability to:
1. Increase flexibility: Wildcards allow for more flexible search queries and file name matching.
2. Save time: By using wildcards, you can search for multiple items at once, saving time and effort.
3. Reduce errors: Wildcards can help reduce errors by allowing for more general search queries, reducing the need for exact matches.
4. Enhance search capabilities: Wildcards enable more advanced search capabilities, such as searching for patterns or ranges of characters.
5. Improve data retrieval: Wildcards can help retrieve data more efficiently, especially when dealing with large datasets or complex file naming conventions.
