Installing, editing and managing PK3's

What is a PK3?

A PK3 (or Pack 3) is a type of file archive (a file containing other files, usually compressed to take up less space) and is essentially the same as a zip folder, just with the extension .pk3. JKA will load files within the gamedata\base (or gamedata\NameOfModYouArePlaying eg japlus) folder as well as the contents of any .pk3 files

Basically, they contain much of the files that make up the game as well as most mods (skins, maps etc) you can download.

Installing PK3s

• Find the file and copy it with crtl+c (If you downloaded the PK3, it was probably in a zip file, if so open up the zip and copy the pk3 inside.)
• Find your base folder. This is usually C:\Program Files\Lucas Arts\Jedi Academy\GameData\base
• Paste the pk3 into your base folder.

If you are using a mod like JA+ or Clanmod you should usually paste into the gamedata\japlus or gamedata\clanmod folder instead of base. You should only use the base folder if you want whatever you are using to work with the base game or with all mods and remember to check the readme for whatever you are installing as some things work differently.

PK3 Naming

JKA always loads PK3s in alphabetical order. If you have too many pk3s added to your base or mod folder sometimes the mods with the earlier name alphabetically wont work properly. This is because the later pk3s alphabetically are effectively loaded over the top of the earlier ones. This also means that if I install two pk3s each containing a file of the same name, one called "file.pk3" the other called "zzzzzzfile.pk3", the version in "zzzzzzfile.pk3" will be used.

In short, if you want to make sure that one skin is displayed further up the menu, or that one particular file is defiantly loaded fully, add a ton of "z"s to the front of its name.

Opening PK3s

• Download packscape, winrar, 7zip or any other file archiver that you like to use.
• Double click a PK3 file to open it. If it asks you what program to use, point it to your choice from above.

   

  Alternatively open the archiver you chose and drag the pk3 you want to open into it.

If you really don't want to download any programs to do this you can take a pk3 and rename it as a zip. For example if i rename assets1.pk3 to assets1.zip I can then just double click it to open it. Remember to rename it back to a pk3 afterwards if you use this method

Editing The Contents of a PK3

You can copy any files you like in or out of the PK3 to edit them and put them back in. You can also delete files or add entirely new ones in the same way as you would when navigating folders on windows. (be sure to click save when you are done if you are using Packscape). But never modify the original assets pk3 files, put your modifications into a new pk3 with a name that comes alphabetically after "assets", that way they will take precedence.
