Diffoniq 2.0 released — the next generation of WDiff32

7 Oct 2026

WDiff32 has a new name and a new version: Diffoniq 2.0 is out. It is the same side-by-side tool for text files, folders and archives, with a much wider scope:

  • Full Unicode support — UTF-8 and UTF-16 files, international file names
  • Archives beyond ZIP: 7-Zip, RAR, tar, CAB and ISO open and compare like folders, nested to any depth
  • Folder synchronisation, comparison reports, rename and move detection
  • HTML help that opens in your browser

Diffoniq 2.0 runs on 64-bit Windows 10/11. Registered WDiff32 users get a Diffoniq 2.x licence free — claim it here. Download the 30-day evaluation, see what's new, or buy a licence. WDiff32 1.59 stays available for 32-bit Windows on its history page.

A public beta is planned. To hear about the beta and new releases first, subscribe to the new WDiff32 Announcements mailing list (a few e-mails per year, unsubscribe anytime). The list is called Diffoniq Announcements today.
