Public Beta v4

TL;DR

Version 4 is now in public beta.

It is available for anyone who wants to try it, but it is not yet considered production-ready and is not recommended for business, professional, or other critical use.

Expect bugs, unfinished features, and frequent changes. Updates may be released several times per week, and settings, features, themes, and other behavior may change between builds.

Please use caution with important or irreplaceable files.

If you depend on the app for daily or production work, Version 3 remains the recommended version for now.

Before you install

  • Public beta: Anyone can try Version 4, but development is still active.
  • Not production-ready: Do not rely on Version 4 for business, professional, or other critical workflows yet.
  • Frequent updates: New beta builds may be released several times per week.
  • No V3 migration yet: There is currently no supported migration path from Version 3. Treat Version 4 as a separate installation and configuration.
  • Settings may change: Preferences, configuration formats, defaults, and available options may change or be reset during the beta.
  • Portable only: Version 4 does not currently have an installer. Beta builds are distributed as portable versions only.
  • Use with care: Bugs, crashes, compatibility issues, data loss, or other unexpected behavior are still possible.
  • Hold off on customization: The new theming system is still being finalized. Avoid investing significant time in custom themes or distributing themes until the format is stable.
  • Please hold off on public reviews: Version 4 is still changing rapidly and is not representative of the finished release. Please send beta feedback directly through the Discord #v4-beta channel instead.

Version 0.0.58.0. Download the portable ZIP, unblock the archive, and extract it to a new non-system folder.

I actually want stable Version 3

What's new

  • Migrated from .NET Framework to .NET 10
  • New theming system
  • New window system with background effects
  • Faster rendering and folder listing
  • Major architectural improvements to support future development
  • 100+ new features and improvements

What's still changing

Version 4 is feature-complete enough for broader testing, but it is not feature-frozen.

During the public beta:

  • Settings and defaults may change
  • The theming system may change
  • Experimental features may change, move, or be removed
  • Compatibility issues may still be discovered
  • UI and behavior may receive additional polish
  • Updates may be released several times per week
  • Existing beta configurations may occasionally need to be recreated
  • Updates are enforced automatically

Breaking changes during the beta will be avoided where practical, but cannot yet be ruled out.

Feedback

Public beta testing is extremely helpful, especially reports involving:

  • Crashes or freezes
  • Incorrect or unexpected behavior
  • Compatibility problems
  • Performance regressions
  • Problems that occur with specific folders or file types
  • UI or usability issues

Please keep Version 4 beta reports and discussion in the Discord #v4-beta channel so issues can be tracked in one place. Join the OneCommander Discord and get the beta testers role.

File beta bugs and feedback in Issues/Feedback GitHub.

About public reviews

Please do not publish reviews or ratings of Version 4 during the public beta.

The purpose of this release is to find problems and gather feedback before Version 4 represents the finished product. Features, performance, compatibility, UI, and settings may all change before stable release.

Criticism and feedback are welcome; please send it through the beta feedback channels so it can actually be acted on.

Looking ahead

Version 4 will become the official stable version once it has received sufficient real-world testing and has demonstrated an appropriate level of stability.

Before that happens, we plan to:

  • Resolve crashes and significant bugs discovered during public testing
  • Finalize the theming and settings systems
  • Improve compatibility and polish
  • Establish a supported migration path from Version 3
  • Provide a normal installation experience

As with Version 3, some functionality may require a paid license once Version 4 reaches stable release.

Development will continue after the stable release with additional features, improvements, and fixes.
