This is a very simple bsa extractor for Skyrim/SkyrimSE BSA, and (since 1.04) Fallout4 BA2 

I didn't find an extractor yet for SkyrimSE, so I quickly made my own. Maybe you can find it useful too.

Usage:
-open a bsa / ba2
-browse content
-select the files you want. (Use Ctrl-A to select everything)
-extract in the folder you want. (Hit 'Esc' to abort the process, if needed)
There is also a filter box on top, so you can quickly find what you are looking for


Note:
Bsa reading is based on the wbBsa.pas and  wbStreams.pas units from xEdit and the modifications I made for sseTranslator/fallout4Translator.
