256 symbols (with extension)\n* Russian letters are **not supported** in the file name\n* Maximum size of file -  1 GByte\n* Archived file has `.xxx` extension \n## Structure\n* 1 Byte - Length of file name (in Bytes) - **N**\n* **N** Bytes - File name\n* 2 Bytes - Number of different Bytes (symbols) in the file (0-256) - **K**\n* **K** blocks (Huffman tree):\n    * 1 Byte - Byte (symbol)\n    * 1 Byte - Encoding length of this Byte (symbol) (in Bits) - **S**\n    * ⌈**S**/8⌉ Bytes - Encoding of this Byte (symbol)\n* 8 Bytes - Length of encoded data (in Bits) - **P**\n* ⌈**P**/8⌉ Bytes - Encoded data\n## Interface - example\n![Interface](https://raw.githubusercontent.com/exsandebest/Archiver/master/examples/screenshots/encoding.png)\n## Authors\n* [exsandebest](https://github.com/exsandebest) ([Repository](https://github.com/exsandebest/Archiver))\n* [klimkomx](https://github.com/klimkomx) ([Repository](https://github.com/klimkomx/HuffmanArchivator))\n* [hensuto](https://gitlab.com/hensuto) ([Repository](https://gitlab.com/hensuto/huffman-archiver))\n\n## Testing\nTo run the Qt-based checks without launching the UI, build the project and execute:\n```bash\nQT_QPA_PLATFORM=offscreen ./Archiver --test\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexsandebest%2Farchiver","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fexsandebest%2Farchiver","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexsandebest%2Farchiver/lists"}
