What is a Windows Cabinet file?

A Microsoft Cabinet file is a compressed archive used to distribute files for Windows software, drivers and updates. Opening the archive lets you inspect those files without installing the package. A cabinet may contain binaries, configuration, documentation and other resources.

This CAB extractor handles supported Microsoft cabinets. Some products use the same .cab extension for a different format, including proprietary InstallShield cabinets, which are unsupported here. Cabinet sets that require missing parts cannot be fully recovered.

CAB files inside MSI packages

Windows Installer packages can contain embedded cabinets or reference external ones. If you have the MSI as well, the MSI extractor explains how to upload it together with its external CAB files. Cabinet members can use file IDs; extracting a CAB alone does not reconstruct the filenames and paths chosen by the MSI installer.

CAB extraction questions

How do I decompile a CAB file?

A CAB is an archive, so the first step is to extract its contents. Supported compiled files inside it, such as .NET assemblies, can then produce readable source. The cabinet itself has no program source to decompile.

Can I open a CAB file on Mac or Linux?

Yes. Use your browser to upload the cabinet and browse the result. You do not need a Windows machine or a local cabinet utility.

Does extracting a CAB install a driver or Windows update?

No. Extraction makes the packaged files available to inspect and download. It does not install drivers, apply updates or recreate a Windows CE installer project.

Why won't my data1.cab file open?

The filename alone does not identify the cabinet format. It may be a proprietary InstallShield cabinet, depend on other cabinet parts, or be damaged. Check the result's explanation and supply any required companion files with the original package.

Extraction limits and partial results

Each upload shares a five-minute extraction and source-recovery budget, with up to 1 GiB of expanded data, 256 MiB per file, 25,000 entries and four nested layers. Worker limits can stop processing sooner. You can browse completed files while processing continues; a ZIP download becomes available when the job finishes.

If a format, version or file cannot be processed, the result explains the limitation and keeps files already recovered. Extraction does not recreate a complete buildable application or the original native source code.
