This tool technically performs “conversion” as follows:

  • Extract CAB content
  • Preserve file names and folder structure
  • Repack in the selected target format

Since there is a command called expand for extracting/listing CAB content on the Windows side, the user’s perception of “this is an archive” is clear.

Supported conversions

  • CAB to 7Z
  • CAB to RAR
  • CAB to TAR
  • CAB to TAR.BZ2
  • CAB to TAR.GZ
  • CAB to ZIP

Which format should I choose?

  • ZIP: The widest compatibility. Default for sending to clients/teams.
  • 7Z: Modern archive standard; for those who want to keep archives uniform.
  • RAR: If it is the standard for institutions/agencies. (RAR production may depend on your infrastructure; if unsupported, the option should be disabled.)
  • TAR: No compression, just packaging. In Linux/DevOps workflows.
  • TAR.GZ (TGZ): Very common package in Linux (tar + gzip).
  • TAR.BZ2 (TBZ2): tar + bzip2; smaller in some content, generally slower.

Tool flow (single interface)

  1. Upload CAB (drag and drop)
  2. Analysis:
    • file list and folder tree
    • total size, number of files
    • suspicious situation: possibility of encrypted/corrupted/multi-part set
  3. Select target format (7Z/RAR/TAR/TAR.BZ2/TAR.GZ/ZIP)
  4. Settings:
    • compression level (fast/balanced/maximum)
    • “preserve folder structure” (default on)
    • output file name
  5. Convert
  6. Download (single output file)

Settings (details)

  • Compression level
    • Fast: time priority
    • Balanced: default recommendation
    • Maximum: size priority, may take longer
  • Folder structure
    • Default: preserve
    • Optional: “flatten” (generally not desired in corporate delivery)
  • Output name standard
    • originalName_target.ext (e.g. driverpack_zip.zip)

Error messages (clear and action-oriented)

  • Corrupted CAB: “File is damaged or missing. CAB content could not be read.”
  • Set/dependent CAB: “This CAB file may be part of a set; extraction could not be completed due to missing parts.”
  • RAR not supported: “RAR output is not supported on this system. Choose ZIP or 7Z.”
  • Content could not be extracted: “CAB content could not be listed. It may be a different CAB variant.” (Clean warning)

Use cases

  • Convert CAB from Windows update/driver to ZIP and share within the team
  • Open CAB content in Linux and produce portable package (tar.gz)
  • Archive standardization: moving CABs to 7Z
