Can someone make a small table which shows what function have different kind of files.
For example:

Server rates config.
Hire you can config you server rates , drop , spoil , karma drop...
Can config him with this file edit.
gameserver\config\rates.properties

Start message "announcements"
After login in server you see message in blue text "Announcement:......"
Can config him with this file edit.
gameserver\data\announcements.txt

All text in game.
You can config in this folder , just need to find text to you need to change.
gameserver\data\html

All prices in server.
With config this file in this folder you can change npc sell prices.
\gameserver\data\multisell

I think that guide will be very usefully for all.
Some can make guide with like that info.

Sorry for my very bad english.

This is called "commented code", and in every program I've seen, comments are always plus or less missing...

What you need is to read wiki, read tutos, read questions, try and make mistake to realize that you don't need any more file to help you in finding what to modify.

And, OMG, there is an error... Modifying multisell folder will not affect"all" price in server, never...

You have to be curious, you have to know a minimum coputer logic and you need to be not noob to launch a server. If you fit one of thoses categories, just forget openning server and go back to play, or go back learn some basics computer functionments...

Sorry to be rude, but you're not the first to ask something really easy and really "findable" just by searching yourself
