  • Extracting files from inside a file archive
    L Luminare

    As far as I can tell its just that file, there are some compiled pyton files there that I have'nt had any luck prying information from, it might be that they hold a sort of a catalog but im unsure. I have been playing around trying to extract the raw data, but I have some problems getting the loop to determine where the data ends and where a new header begins.

  • Extracting files from inside a file archive
    L Luminare

    Hi, I was wondering if anyone could push me in the right direction on this one. I got a file with multiple files inside it like an archive, its not compressed it just seems like the files are stacked inside the file. I can read the headers of head indevidual file with a hex reader, so I have indetified that the file contain several wav files, some dds files and jpeg, avi etc. what I have visioned is a loop that goes trough the file and each time it identifies a header it dumps that header and the following data to a file and continues to read on sortof splitting the file up again. Im unsure if I should have a list of just the data headers im expecting to find or if I should make a struct with the structure setup of all the file spesification's im expecting and have the loop match against that. Also what would be the most efficient way to go trough the file, its pretty large (about 4-500mb)? structure example: typedef struct _avimainheader { _FourCC_ fcc; DWORD cb; DWORD dwMicroSecPerFrame; DWORD dwMaxBytesPerSec; DWORD dwPaddingGranularity; DWORD dwFlags; DWORD dwTotalFrames; DWORD dwInitialFrames; DWORD dwStreams; DWORD dwSuggestedBufferSize; DWORD dwWidth; DWORD dwHeight; DWORD dwReserved[4]; } AVIMAINHEADER;
