Archiver is a tool for data archiving, which handles UNG files. It implements encrypting to avoid unauthorized data access.
UNG files are transparent to the engine, and their content is handled as not packed. (For more details about file packing, see File System).

The maximum archive size is 2 GB.

To invoke Archiver, run ung_x86.exe (in Windows) or ung_x86 (in Linux) from a command-line console (the 64-bit version has x64 postfix).

Command Line Options

Archiver recognizes the following command-line options:

  • -p PASSWORD— set a password. It should be the same password as passed on engine initialization on the C++ side.
    You can skip password setting if it is not required. The engine supports loading UNG packages without password protection even if the password was specified on its initialization.
  • -x FILE— exclude the specified files from packaging into the archive.
  • -o NAME— name the output archive.
  • -e NAME— extract files from the archive.
  • -i NAME— print archive statistics.

Usage Examples

The following creates an archive named files.ung that contains files file.txt and file.tga:

Shell commands
ung_x86 -o files.ung file.txt file.tga

The following extracts all files from the archive created above:

Shell commands
ung_x86 -e files.ung

The following prints statistics related to the archive:

Shell commands
ung_x86 -i files.ung
