Installing V4.6.5 over 4.1 AppData questions

[Rose]

I did a test run of installing V4.6.4 on the Win 8.1 laptop in Dec 2014  
then discovered recently it wasn't a desirable version. There was no 
previous Gnucash installed on this laptop.
In preparation I had copied the customized AppData/Gnucash/containing 
the 4.1 folders and a copy of the actual account files
In Dec. I did not edit the environmental file within the 4.6.4 version
Yesterday I installed V4.6.5 over top of v4.6.4 which it uninstalled
Edited the environment file within the program folder etc/environment to 
point to the AppData/Gnucash folder before opening the software.
The environment file does not contain quite the same text as the 4.1 
file and it appears that an AppData/.qnucash folder was created, likely 
at the first install. It contains the actual gnucash books .gcm file for 
the accounts.
So I have .qnucash and my own created folder Gnucash in the AppData AND 
the environment file pointing to the HOME Appdata/Gnucash
I'm not entirely sure that the my entered  path is being referenced 
since there now are two in the last two lines of the environment 
contents This environment file is not quite the same as 4.1.
When I open the account the contents of the data appears as a replica of 
content viewed  within 4.1 on the Win 7 desktop

When I install 4.6.5 into the Win 7 desktop it is going to automatically 
create the AppData/.gnucash file and I presume pick up the active book.
My Questions are:
#1.In that environment file for 4.6.5 is the edit procedure the same 
routine BEFORE opening 4.6.5 as it was for version 4.1?
The last line is:
XDG_DATA_DIRS={GNC_HOME} /share;{XDG_DATA_DIRS};/usr/local/share;/share
(There is a gtkfilechooser.ini  within AppData/Local/gtk-2.0)
I have inserted as the last line on the Win 8.1 install:
HOME={Appdata}/Gnucash
This configuration appears to be working correctly in 8.1 but I'm not 
totally sure since both AppData folders (.gnucash and Roaming/Gnucash) 
still exist.
Also V4.1 has many extra folders with nothing in them in that 
AppData/Gnucash folder of mine therefore I wonder if I need that 
construct at all with 4.6.5.

Question 2: Therefore the edit of the environment file is not needed 
after installing 4.6.5 and I can remove my original user-created 
subfolder in AppData?
