[8FS_Bulau]

ok guys thanks for the reponses but i doesn't have a clear answer on my post, Sorry....
But Bottom line is my question that no one answered what are W0 files and how do i open them or put them in the in the installation, or even even change them to something else like RAR files if that is possible.

Don't worry about the WO# files. You have a total of eight files...just make a new folder... make it anywhere...call it anything...it doesn't matter...
and put all eight files into it.

Then open that new folder, if it isn't already, and run (double-click) the file called HSFX_Version_4.exe and direct the installation to the game folder you want to upgrade to HSFX. All the other .WO# named files will look after themselves and install automatically. Once that has run its course, you will have installed HSFX v4.0

Then run (double-click) the file named HSFX_Version_4_1.exe and direct it to the same game folder as you did for 4.0 above.
