Dir

FilenameArray = Dir ( Directory AS String [ , Pattern AS String , Filter AS Integer ] ) AS String[]

Returns a string array that contains the names of files located in Directory that matches the Pattern and the Filter.

The pattern can contain the same generic characters than the LIKE operator. If no pattern is specified, any file name is returned.

The filter specifies what kind of files will be returned, by specifying one or a combination of the file type constants. If Filter is not specified, all files and directories are returned.

The file names returned are relative, they do not contain the searched directory.
