Rename xmls.txt to xmls.zip and then you can open it and see all the xml files inside.
First you rename the original xmls.txt to .zip and extract them in a folder, then you extract the new xmls from 20160429xmls.zip and replace the old ones, then you archive the folder and name it to xmls.txt and replace the original in the www folder.
There's a tutorial for this as well, except it's not in English, but the instructions are pretty forward:

As for me, I have no idea where to put the "btstore" and even after getting the server to say it's online and working, whenever I try to connect it gets stuck at reading xmls. Guess I did something wrong somewhere.
Also another working combo for the id/password for the vmware thing could be: root/rx123
