We have an interface file that we want to delete for security reasons once we have processed the file.  But, deleting it from the Application  Engine was not as straight-forward as I would have thought.

This does not work:

RemoveDirectory("c:\temp\mytextfile.txt", %FilePath_Absolute);

So, Java to the rescue — this does:

Local JavaObject &javaFile;
&javaFile = CreateJavaObject("java.io.File", "c:\temp\mytextfile.txt");
&javaFile.delete();

Update (8/20/2014):

Back when I wrote this post, I missed seeing the .Delete() method of the File API object.  That would be the better way to make this work.  Here’s an example:

Local File &file;
&file = GetFile("c:\temp\mytextfile.txt", "W", "A", %FilePath_Absolute);
&file.Delete();

(Thanks Tim and Andrew for pointing this out.)
