Description:
   A Java based CFML UDF to get a list of files from the specified path.

Parameters:
  1. path (String, required)
           The path or filename to start getting a list of files from. This can be a full or relative path.

  2. filter (RegularExpression, Default: )
           A regular expression to filter the results by. Default is no filter.

  3. type (Numeric, Default: 0)
           Return all types, directories only, or files only.

           Values:
    • 0 - Return both files and directories.

    • 1 - Return directories only.

    • 2 - Return files only.

  4. recurse (Numeric, Default: 0)
           How many levels of sub directors to recurse through. 0 is none, -1 is all.


Returns:
       A query containing the following columns: fullpath,directory,name,extension,type,isDirectory,isFile,size,dateLastModified,isHidden,isReadonly,children

Requires:
       queryConcat()

Sample Use:
