QUICK ANSWER
Is it possible to convert DIAGCAB to ZIP?
Yes - DIAGCAB converts to ZIP.

Right-click the .diagcab in 7-Zip and extract to a folder, then select all extracted files and add them to a new ZIP. The ZIP contains the troubleshooter's PowerShell scripts and metadata but cannot run the troubleshooter - only the original CAB structure works with msdt.exe.

Why convert DIAGCAB to ZIP?

ZIP opens on every operating system without special tools, while a CAB file needs a dedicated handler on non-Windows systems. Repackaging as ZIP makes the files portable and lets you share the scripts for review without sending an executable-looking .diagcab.

How to convert DIAGCAB to ZIP

7-Zip OPEN-SOURCE

Right-click the .diagcab and choose 7-Zip > Extract to folder, then right-click the extracted files and choose 7-Zip > Add to zip archive.

WinRAR APP

Use WinRAR to extract the .diagcab contents to a folder, then add those files to a new ZIP archive.

Quality & what to watch

  • The resulting ZIP cannot run as a troubleshooter - msdt.exe requires the original CAB structure and will not accept a ZIP.
  • All inner files (PowerShell scripts, answer file, localized resources) copy across intact; ZIP does not execute or alter them.
  • A .diagcab is already a CAB archive, so renaming it to .cab and opening it in Explorer is an alternative extraction method without needing 7-Zip.

Frequently asked questions

Can I use Windows built-in tools to make the ZIP?
Yes - rename the .diagcab to .cab, open it in Explorer, copy the files out, then right-click and choose Compress to ZIP file (Windows 11) or Send to > Compressed (zipped) folder (Windows 10).
Will the ZIP work as a troubleshooter on another machine?
No - msdt.exe requires the original CAB format and will not accept a ZIP archive.
Is it safe to open a .diagcab in 7-Zip?
Yes - opening with 7-Zip only reads the archive; it does not execute any scripts. You can inspect the .ps1 files safely in any text editor.
