The Grimoire download contains a series of files that need to be attached to a module in order for this content to work during gameplay. The download comes in .rar format. A program that can read and extract .rar files, such as WinRAR, will be needed. The download is formatted in .rar due to its smaller compression size, making it more friendly for dial-up users to download. As always, .hak files should be placed in the hak directory, .tlk files in the tlk directory, and .erf files in the erf directory.
