A wildcard is a character that can be used as a substitute for any of a class of characters in a search. Wildcard characters are often used in place of one or more characters when you do not know what the real character is or you do not want to enter the entire name. In Active@ UNDELETE three types of wildcard are used: star or asterisk(*), question mark (?) and number sign (#).
Examples of using wildcards:
|Asterisk (*)||docum*||Use the asterisk as a substitute for zero or more characters if you are looking for a file that you know what it starts with and you cannot remember the rest of the file name. The example locates all files of any file type that begin with "docum" including documents.txt, document_01.doc and documentum.doc.|
|docum*.doc||To narrow the search to a specific type of file, include the file extension. The example locates all files that begin with "docum" and have the file name extension .doc, such as document_01.doc and documentum.doc.|
|Question mark (?)||doc?.doc||Use the question mark as a substitute for a single character in a file name. In the example, you will locate the file docs.doc or doc1.doc but not documents.doc.|
|Number sign (#)||doc_###.doc||Use the number sign (also known as the pound or hash sign) as a substitute for a single number in a name. In the example, you will locate the file doc_012.doc or doc_211.doc but not doc_ABS.doc.|
