Tools of the trade: how modders and archivists work with GXT files Working with GXT files tends to be accessible: the format is simple, and a range of community-created editors, extractors, and repacking tools make swapping strings straightforward. That accessibility is a double-edged sword. It democratizes preservation and creative expression, but it also makes it trivial for anyone to distribute altered or “original” files, increasing the circulation of potentially controversial content.
