Template:BSA Extraction Warning

From Nexus Mods Wiki
Jump to: navigation, search

Overview

This template is so it may be included in several instances in the articles:

Programs and Tools

  • BSAOpt Tool for extracting the contents of BSA files. Note this tool unpacks the entire BSA file. It does not easily allow for unpacking a single file.
  • BSAExtractor (BSAE) Tool for extracting just one or the entire contents of BSA files.
  • FOMM - Forked Mod Manager with built-in BSA file extraction and repacking.

Detail

(See the Skyrim thread BSAs and You for details about the pros and cons of "Bethesda Software Archives" (BSAs), but bear in mind such files in previous games, like Oblivion, FallOut3 and Fallout New Vegas, don't have "strict order" like in Skyrim. Games prior to Skyrim don't support overriding of assets in archives using other archives; only loose files can. If the same resource is contained in several BSA archives, those games won't use it from the last BSA on 100% of occasions. They may grab the resource from a random one of the BSAs containing the same file.)

WARNING! Do not unpack BSAs directly into your game "Data" folder; potentially overwriting any mod files. The tools don't ask you to confirm the overwriting, either. All the hair textures unpacked to "loose files" will go through the head models in that case; because that's what happens when hair is not packed in a BSA. "Best practice" is to unpack to a unique folder (they are large: 1-2GB) and manually drag the desired files to the appropriate "Data" folder as needed.
