types of filelists

I'm making this DC client in PHP. I hope some of you can answer my questions about filelists in DC.

What formats are the filelists in?
I know about the .bz2 type of list but I'm not sure with the .dclst. Do I need both?

Any answers migth help me out some...

umm, isn't the .bz2 a compressed .dclst ?

No, it's not. A .bz2 decompresses into a plain text file whereas a .DcLst file is binary.

Try it yourself.

Binary? What does that mean? How can I generate/make one? And how do I open it?

Please check the DC++ source.

I believe it involves Huffman encoding somehow, and in the 5 minutes alloted to answer this question, I couldn't find any documents on the reverse engineering of the file lists.

I posted details and source code for the huffman scheme used in .dclst files a while ago. See here.

Hi!

Does anyone have some code to decompress .bz2 files? (I would prefer Pascal (Deplhi) or C if possible...)

thanks

For C, you could use the bzip2 library which is part of DC++. For Delphi, I'm sure you could find something via Google.
