Remarks

Separate the file filters with a semicolon as shown in the example.

Note: At this time, multiple groups of filters are not supported.

If default name is given, options must also be given. If none of the options are wanted, use 0 for options.

Special Windows folders (such as "My Documents") can be sometimes be set as the init dir.

Example

$message = "Hold down Ctrl or Shift to choose multiple files.";
 
$var = FileOpenDialog($message, @WinDir, "Images (*.jpg;*.bmp)", 1 + 4 );
 
If (!$var)
{
    MsgBox("No File(s) chosen");
}
Else
{
    $var = Replace($var, "|", @CRLF);
    MsgBox("You chose $var");
}
