OK. This is alot of
to type but it's Christmas day and all so I'll do it for ya
Firstly, As explained here, this only works on the PC version with AFSExplorer tho I think AFSExtract can do it too.
It is important to do these steps in order--->
Open your data_x.afs file
Select your file that you will be replacing
Right click & choose import
It will complain that "There is no room for this file! you must use the rebuild funtion to reserve more space Do you want to set a new reserved space for this file?
SELECT YES
This will open up the space according to how much more space is needed for the new file.
Press "Ctrl+R"
Where it says "Size difference=_____"
make sure there is something there besides 0 or the space wasent allocated.
Click "Regenerate AFS"
Select a different folder then your "dat" folder (which it usually defualts to) name the file "data_x.afs (x being your language code, like _e for English _i for Italian)
Click "Save"
Now it will begin regenerating
This will take forever depending on how much more room your getting and how big your AFS file is to begin with.
When it is finished go up to "File" select "Import AFS" go to your new AFS file you made (if it doesent appear it might not be named correctly and you will have to find it manually and name it with the ".afs" extension.
Load the afs and go to your file that you wanted to replace
The space needed for the replacement is now available!
Import the file again and it should go in fine!
Then delete or backup your old AFS file and put your new one in the "dat" file.
Take a breath....AHHHHHHH...your done!
Go Play!!!
