Extracting File System from swfl File

[MichaelCB]

Hey,
I have a pdx file that has been extracted to a file system that includes the folder ROOT\swe\swfl.
The folder contains bsw files that can each be extracted to two files: bin and xml.
The xml file represents info about the bin file such as signature/compression/etc.
It seems that these files were created using SWE-Generator.

The bin files are archived, but I managed to receive an unpacked version of them.
My current problem is that the unpacked version is still one bulb of data, and I need to extract from it a file system.

Standard tools such as 7zip/binwalk/etc fail to extract a file system from it. I suspect this is something proprietary for BMW.

Would really appreciate some help here
