Fixes various issues with vanilla Skyrim meshes that causes them to render incorrectly. A mesh only animated forge water replacer with refraction. Simply re-installing the game won't do that - Steam won't delete the stuff you added to its folder structure. A very WELL-made mesh-only solution for animated water in wells and sewers. You just dump the loose files into Data, and they work until you remove them. This means that some mods don't need an active ESM / ESP to do their thing. When Skyrim loads, if it spots a loose file in the same location as one of the files found in a BSA, then the BSA's copy gets ignored and the loose file is used instead. Many mods add "loose" files to your Data folder - files that may have the same purpose as those in the BSAs.


The game treats them as a virtual copy of the Data folder in their own right. These are basically giant zip files, containing assets such as textures, models, maps, and so on. Originally posted by Bomb Bloke:In Skyrim's Data folder are a bunch of large files with a BSA extension.
