| Hi,
I have a binary file and I don't know with what software or algorithm
it was created. I think it might be compressed or encrypted. I tried
to reverse engineer it and thats what i found out:
1) The file begins with "PZ 2.0" string
2) File has 188 byte header
3) offset 8, length 4: holds number equal to the size of header (188)
4) offset 12, length 4: holds size of some kind of table. This table
begins after the header.
5) offset 16, length 62: unknown
6) offset 78, length 110: looks like comment
7) offset 188, length 243344: some table, it looks to me like sequence
of numbers, it begins with 0 and end with 0:
00000000 05000000 0A000000 10000000 16000000 1B000000 21000000
26000000 2B000000 30000000 37000000 3D000000 43000000 4A000000
52000000 59000000 63000000 6C000000 73000000 7A000000 82000000
89000000 8F000000 95000000 9C000000
****************
015D0B00 0B5D0B00 155D0B00 1C5D0B00 225D0B00 2F5D0B00 3B5D0B00
425D0B00 485D0B00 545D0B00 5C5D0B00 665D0B00 725D0B00 7C5D0B00
875D0B00 915D0B00 9B5D0B00 A65D0B00 B15D0B00 00000000
8) After the table is data, it takes the rest of the file size.
So, does anyone know what kind of format this is? Any information
would be usefull. Thanks

Where did you get the file from? Knowing the host machine or
operating system would help.

I know that this file is used only on windows. It is like database.
The software which reads it, s s somewhere in the file then reads
32KB of data deciphers it and gives the results.
