Hello! I have some custom dumped files that are probably compressed with Huffman, can anyone decompress them with code. Also, I found the following codes and lengths for it, can we recompress it back into original too?

Code:
static const uint32 Codes[16][16] = {
   { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F },
   { 0x00, 0x01, 0x03, 0x05, 0x07, 0x09, 0x0B, 0x0D, 0x0F, 0x13, 0x15, 0x17, 0x19, 0x1B, 0x1D, 0x1F },
   { 0x00, 0x02, 0x01, 0x09, 0x05, 0x15, 0x0D, 0x1D, 0x03, 0x13, 0x0B, 0x1B, 0x07, 0x17, 0x0F, 0x1F },
   { 0x00, 0x02, 0x06, 0x01, 0x09, 0x05, 0x0D, 0x1D, 0x03, 0x13, 0x0B, 0x1B, 0x07, 0x17, 0x0F, 0x1F },
   { 0x00, 0x04, 0x02, 0x06, 0x01, 0x09, 0x05, 0x0D, 0x03, 0x13, 0x0B, 0x1B, 0x07, 0x17, 0x0F, 0x1F },
   { 0x00, 0x04, 0x02, 0x0A, 0x06, 0x0E, 0x01, 0x09, 0x05, 0x0D, 0x03, 0x0B, 0x07, 0x17, 0x0F, 0x1F },

These are the Huffman tables for the Bink video codec. They won't help you.
