There is already a topic about these files I guess:
viewtopic.php?t=1840

The str files are compressed with the RefPack algorithm:

Code:

comtype dk2
goto 0x34
get SIZE long
goto 0x44
get ZSIZE long
savepos OFFSET
get NAME basename
clog NAME OFFSET ZSIZE SIZE

The decompressed file has the LCH2 magic at the beginning.

Anyway already exist tools so find and use them.

The packages could have many files and they are chunked, and not all chunks are always compressed, only when they have the "kapR" identificator. Something like this (Pascal):

Code:

type
   TDataChunk = packed record
      Magic: Array[0 .. 3] of AnsiChar;
      ZSize: UInt32;
      ComType: Array[0 .. 3] of AnsiChar;
   end;

type
   TData = record
      Magic: Array[0 .. 3] of AnsiChar;
      HeaderSize: UInt32;
      RDHS: Array[0 .. 3] of AnsiChar;
      Unknown: Array[0 .. 27] of Byte;
      DataSize: UInt32;
      Chunks: TArray;
   end;

type
   TStr = record
      Magic: Array[0 .. 3] of AnsiChar;
      HeaderSize: UInt32;
      Unknown: UInt32;
      Files: TArray;
   end;
