MMORPG game file question.... PROS PLZ HELP T.T

[Michael99MS]

I want to edit some file of my game....

And there is some files I dont actually know what it is....

So I want to ask... what is .vfs , .dll , .ii2 files??

Here is the screen shots...

.dll Files you can edit with Reshack/
Much as i know resourcehacker can completely decompile DLL's and EXE's

Looked for a bit for something for you're .VFS files, this is all i could come across. https://www.fileinfo.com/extension/vfs
Nothing really looked like it helped, but there's still the link.

As for the ii2. it seems pretty unknown on the internet. File Extension .II2 Details
Some sort of install file.
