rogue+skwr,

here is the how-to exclude search paths for the KAGU scanner, it is most convenient to do this from your home PC/Laptop via WLAN connection to the N800.

0) prerequisite: install openssh on the N800 via this link:
http://maemo.org/downloads/product/openssh

1) on your home PC/Laptop, download WinSCP http://winscp.net

2) find out which IP adress your N800 sits on in your home WLAN network (look in your home router configpage, e.g. mine is on 10.0.0.5)

3) start WINSCP, connect to this IP, use the root account, PW is rootme (DANGER! DANGER! DANGER!)

4) ignore the "missing ssh signature" etc thingy (to establish ssh keys is a real pain in the....)

5) you will find the N800 directory tree on the right side, go up to the root, from there navigate to /usr/lib/kagu

6) you will find the file "globals.py" in this folder

7) copy this file to your PC where you can find it, open this local file now in some text editor (I use PSPAD: http://pspad.com )

8) search for the line "path_a" (disq has written another path_a line for his own tests in there, but it is commented out by the "#" sign)

9) insert a "#" sign in front of the currently active path_a line to make it inactive, you might want to write "#original" at the end of this line so you have it for later reference

10) if you just want mmc1 (the external card) to be scanned, copy or write the following definition in a new line:
path_a = ['/media/mmc1']
Skwr: you can add any subfolder to this path (Like: /music)

11) save the globals.py file and re-upload it via WINSCP to the N800 to the same destination where it was, overwriting the (unedited) existing file

12) start KAGU SCANNER, do a full scan, it will now omit the internal card, your Navicore voice files will NOT show up in KAGU

13) start KAGU and delete the existing playlist

14) life happily ever after

just did all those steps (except #14) and it worked here on my N800, no other complications so far ..--))))))

if you do not have a home WLAN network you can do this also via XTERM and gainroot/becomeroot directly on the N800, but it is much more tedious (IMHO, as I am not familiar with XTERM shell commands...)

good luck,
karl.
