addToFolder(): The copy version of the file is deleted, if the original version is deleted

问题

I started doing development with google scripts few days ago and recently joined stackoverflow. I have a problem with addToFolder() function. I have the following piece of code that copies my new spreadsheet into a folder (test/sheets) in my Google Drive:

var ss = SpreadsheetApp.create("test");
var ssID = ss.getId();
DocsList.getFileById(ssID).addToFolder(DocsList.getFolder("test/sheets"));

My problem is that now I have 2 versions of the same file (one in the root of my Google Drive folder and the other in test/sheets folder), whenever I try to delete either of the copies, the other copy is deleted as well. Is there a way to delete the old file and keep the new one OR is there a way to create the file in the desired folder in first place?

EDIT :

thanks for you quick response. I played with this for couple of hours but still have problem copying the file to the destination folder. The problem is that even when I use makeCopy Method of the file, still addToFolder is the only option to mention the folder. Again this ends up having the tagged filename in the destination folder. I had the same problem with the copy method.
Here is my new Code:

var SetLocationFile = "icompare/sheets/stocks" 
var FolderID = DocsList.getFolder(SetLocationFile); 
var FileID = DocsList.getFileById(ssID); 
FileID.makeCopy("test3").addToFolder(FolderID);

Folders in Google Docs\Google Drive are actually tags. When you "add" a file to the folder "test/sheets", you do not make a copy of your file, you just attach the tag "test/sheets" to it. Now the same file is shown both in the "test/sheets" folder (i.e. in the list of all files with the tag "test/sheets") and in the root. If you wish to make a copy of the file, you should use the copy method. (Please let me know if I just misunderstand your question.)

I realize this is an old questions but you can simply use .removeFromFolder(DocsList.getRootFolder()); to remove the file from the root folder.

I would also like to know the answer to this question.. seems rather "weird" that the API does not even provide a way to create spreadsheets and place them in a certain map? And no, I do not want a Copy of the file, I want the file to be in a specific map and in no other map...
