I have a macro where I use this to open a file:

FName = Application.GetOpenFilename
Later in the macro I need to activate the window of that file again (after activating another one) with this:

Windows("im453.txt").Activate
How can I use the FName variable to do it without hard coding the name?

I think the problem is that the FName contains the full path, so how do I delete the left characters of FName up until the last "\" and call it FName2?
