folders.

Example
The following code gets a list of all the text (TXT) files in the C:/temp folder and displays the
list in an alert message:
var folderURL = "file:///c|/temp";
var fileMask = "*.txt";
var list = DWfile.listFolder(folderURL + "/" + fileMask, "files");
if (list){
alert(folderURL + " contains: " + list.join("\n"));
}
DWfile.read()

■ The fileURL argument, which is expressed as a file:// URL, is the file you want to read.

with the contents of the file:

alert(fileURL + " contains: " + str);
