Overview

File compression is a way to reduce overall file size without losing any of the primary data to make large files more manageable. This Universal Extension provides the capability to compress and decompress a file or directory, with or without password encryption.

Version Information

Template NameExtension NameVersionStatus
File Compressionue-util-compress1 (Current 1.3.0)Fixes and new Features are introduced.

Refer to the changelog for version history information.

Key Features

FeatureDescription

Actions

  • Compress files or directories.
  • Decompress zip files with files or directories.
Other
  • Support for AES-256 password encryption for files.
  • Support for 7-Zip (Windows/Linux) and p7zip (Linux).
  • Support for Embedded (Linux).

Software Requirements

AreaDetails
Universal Controller

Universal Controller Version >= 7.3.0.0.

Universal Agent & Python version

Requires Python version 3.7. Only Agents of version >= 7.3 are supported.

  • 7z Archiver supports Windows and Linux agents.
  • Embedded Archiver supports Linux agents.
Software Requirements
  • 7zip command line tool. 7-zip or p7zip version 15.05 or newer is required to be installed in Universal Agent, tested with 7-zip 21.06 and p7zip 16.02.
  • Embedded Archiver. This Archiver is part of the standard Python Standard Library. Zlib library is also wanted but not needed for better compressions.

More information about the Agent Requirements of 7-Zip can be found here.

Configuration Examples

Scenario A

Compress a file with AES-256 password encryption.

Scenario B

Decompress a file with 7zip(custom path) Archiver.

Scenario C

Compress a directory with “Embedded (Linux)“ Archiver.

Scenario D

Decompress a multi-folder zip file with “Embedded (Linux)“ Archiver. Note that when Output File or Directory is not given, the zip is extracted at the same folder as the Source File or Directory with the same name in the example test_folder. If Output File or Directory/Output exists then a folder with the name test_folder_ followed by the first available number is created. For example test_folder_1.

Extension Output

Attribute "changed" is always true in a successful execution of a task. In case of failure, no extension output is produced.

Integration Modifications

Modifications applied by users or customers, before or after import, might affect the supportability of this integration. The following modifications are discouraged to retain the support level as applied for this integration.

  • Python code modifications should not be done.
  • Template Modifications
    • General Section
      • "Name", "Extension", "Variable Prefix", "Icon" should not be changed.
    • Universal Template Details Section
      • "Template Type", "Agent Type", "Send Extension Variables", "Always Cancel on Force Finish" should not be changed.
    • Result Processing Defaults Section
      • Success and Failure Exit codes should not be changed.
      • Success and Failure Output processing should not be changed.
    • Fields Restriction Section
      The setup of the template does not impose any restrictions, however with respect to "Exit Code Processing Fields" section.
      1. Success/Failure exit codes need to be respected.
      2. In principle, as STDERR and STDOUT outputs can change in follow-up releases of this integration, they should not be considered as a reliable source for determining the success or failure of a task.
