I answered your remark to let you know that I am advanced, I am not upset with you. I would very much like to express my heartfelt thanks to you or anyone for a positive answer though. I am explaining the problem the best as I can.
Do you or anyone else get a Playlist file created with the word "New" in it? Is the question I am now asking.
Def001.hst
Def001-new.hst
Def002.hst
Def002-new.hst
Def003.hst
Def003-new.hst

The manual says:
If you ever need a second Playlist, click the File menu New command. This immediately creates a new Playlist .hst file in memory and saves it to the hard drive when you add the first song. It stores in the \Playlist folder. The file is automatically named "def002.hst" for the second one created, which automatically increments to 003, 004, etc. for each new one created.

I understand what the manual says and it does works correctly. But that is for new files that you will create. Mine are already created.

Question #2 and #3
I have Def001’hst opened. How do I close it and open Def002.hst.
I've been using the New command, then the Open command. And I see the newly created file in the context window Def001-new.hst. Am I doing something wrong? Why is the file being named as such? The manual doesn't say that.
Save will not open the context window. I can use SaveAs then I have to name the file. I can only close the file by using New.

Here is the rest of the manual on the subject:
Clicking the File menu Save Command updates your Playlist file on the hard drive. However, Hoster automatically saves the Playlist with every change as part of its Crash Recovery protection.
Save As a New Project

The File menu Save As Command creates a copy of the open Playlist with a new filename in the same or a different folder. It always presents the default Hoster\Playlist folder, which we recommend using so you always know where they are. Choosing a different folder changes the default folder that appears the next time.
