I have some weapon files a friend of mine sent me and I am totally clueless as to how I can get them to transfer to my player. They are just .d2i files, and I have no idea where I can put them in the directory...

Any help?

Next time, don't make two threads.

In order to use those files, you need Hero Editor (check our downloads section), or you could alternatively use ATMA (google it).
