This section is dedicated to the library for working with 7z archives in 1C:Enterprise, OneScript and CLI. This page describes all the actions necessary to get started

Getting Started​

The library provides capabilities for working with 7z format archives: creating archives with various compression settings, extracting existing archives, working with password protection and encryption.

Key Features​

Archiving Directories

The АрхивироватьКаталог function allows you to pack files from a specified directory into a 7z archive. You can specify the path to save the archive or get it as binary data.

Каталог = "C:\МойКаталог";
ПутьАрхива = "C:\Архивы\архив.7z";

Результат = OPI_7z.АрхивироватьКаталог(Каталог, ПутьАрхива);

Extracting Archives

The РазархивироватьКаталог function allows you to extract a 7z archive to a specified directory. Working with password-protected archives is supported.

ПутьАрхива = "C:\Архивы\архив.7z";
КаталогНазначения = "C:\Распаковка";
Пароль = "МойПароль123";

Результат = OPI_7z.РазархивироватьКаталог(ПутьАрхива, КаталогНазначения, Пароль);

Archiving Settings​

The ПолучитьСтруктуруНастроекАрхивации function returns a structure with additional settings for creating an archive:

  • password — password for archive protection
  • method — compression method: Lzma2 (default), Lzma, Bzip2, Ppmd, Copy
  • level — compression level from 0 to 9 (default 6)
  • solid — use solid archiving (single stream compression): True/False (default)
  • encrypt_header — archive header encryption: True (default when password is present)/False
  • threads — number of threads for LZMA2 (default 1)
  • chunk_size — data chunk size when using multiple threads
  • dictionary_size — dictionary size for LZMA2
  • ppmd_order — model order for Ppmd method
  • ppmd_memory — memory size in bytes for Ppmd method
  • filters — array of preprocessing filters: X86, PPC, IA64, ARM, ARM64, ARM_THUMB, SPARC, RISCV, DELTA
  • delta_distance — distance for DELTA filter (default 1)

Example of using settings:

Настройки = OPI_7z.ПолучитьСтруктуруНастроекАрхивации(Истина);
Настройки["password"] = "СекретныйПароль";
Настройки["method"] = "Lzma2";
Настройки["level"] = 9;
Настройки["encrypt_header"] = Истина;
Настройки["threads"] = 4;

Результат = OPI_7z.АрхивироватьКаталог(Каталог, ПутьАрхива, Настройки);
tip

For maximum compression, use the Lzma2 method with compression level 9. For faster archive creation, lower the compression level or use the Copy method

important

When using header encryption (encrypt_header = True), file names in the archive will also be encrypted and will not be visible without entering the password
