cFileSkeleton 
Specifies a file skeleton so you can store information about files with names or extensions that match a search criterion. For example, the criterion can be all tables, all text files, all files with names that have A as their first letter, and so on. Such general searches are done by including the wildcards * and ? in cFileSkeleton. A question mark represents a single character; an asterisk represents any number of characters. You can use any number of wildcards in any position within the file skeleton. 
You can specify a drive and/or directory to search for matching file names. If you don't specify a drive and a directory, Visual FoxPro places information about files in the current directory into the array.
