For the OGG files you have to extract them first (with BAE tool), erase them out of all the files (with xtool erase command), compress them with oggre. After installation, you have to put all the OGG files back inside the original bsa files (with xtool decode command + XTL file).

BIK file use bpk.

Edit: You can also use bethesda.bms with quickbms instead of BAE if you want.

Edit 2:

 17:55:35 - Selected ARC/DS method for Data1a-01.bin was: xtool:mzlib:dd3+lolz:d81:mtt1:mt12:mc1023
 17:55:35 - Selected ARC/DS method for Data1b-01.bin was: xtool:mflac,l8
 17:55:35 - Selected ARC/DS method for Data1c-01.bin was: oggre
 17:55:35 - Selected ARC/DS method for Data1d-01.bin was: 7zdll-pm:m0=mp3det:m1=packmp3c
 17:55:35 - Selected ARC/DS method for Data1e-01.bin was: bpk+xtool:dd3+lolz:d81:mtt1:mt12:mc1023

 18:53:04 - Overall input size: 11,92 GB
 18:53:04 - Overall output size: 5,41 GB (Ratio 45.41%)
 18:53:04 - Overall conversion time: 00:57:28

Install time + decoding BSA files 10 minutes.

Edit 3: Keep in mind that the input size is a bit inaccurate due to extracted files, as the BSA files are still the original size but with zero'd data inside.

Good evening and thanks for your help! These are my results:

One cons is decompression time: about 19 minutes! How can I reduce this time? How did you obtain 10 minutes of decompression time?
