npk - neat package system [en:pack]

Why files should be packed?

  • Open multiple files vs Open only one file.
    • If you want to open multiple files in your application, kernel should traverse FAT(file allocation tables). It needs lots of time - sometimes even longer than load files into memory. npk has its own list of files and also supports hash table for large packages. Yes, npk is a small logical file system itself.
  • Encryption and Compression
    • tar can archive files into a package. But it needs gzip or something to compress files. npk embeds xxtea encyption and zlib compression for convenience. You can just read / write files via npk API, no concern.
