Why Explore Better Exists

Windows Explorer is familiar, but demanding file work quickly outgrows it. Large folders can feel slow, multi-folder work needs too many windows, destructive operations provide limited recovery context, and advanced jobs such as disk analysis, synchronization, duplicate finding, indexing, and automation usually require separate applications.

Explore Better was built to provide one focused Windows workspace that:

• stays responsive in very large folders;
• makes source and destination panes visible at the same time;
• treats copy, move, overwrite, sync, and delete work as inspectable operations;
• combines everyday browsing with disk analysis, search, indexing, previews, and automation;
• runs as the current user for normal browsing instead of requiring administrator rights;
• can integrate with Explorer when wanted, while keeping that integration optional and reversible.

The aim is the depth of a serious Explorer replacement without giving up speed, understandable controls, or recovery when a file operation is interrupted.

Install On Windows

Requirements

• Windows 10 or Windows 11, x64
• A normal Windows user account
• Administrator approval only when Windows itself requires access to a protected location

Recommended Installation

1. Open the latest release.
2. Download ExploreBetter- -x64-setup.exe.
3. Download SHA256SUMS.txt from the same release.
4. Verify the installer checksum in PowerShell:

Get-FileHash .\ExploreBetter-*-x64-setup.exe -Algorithm SHA256

1. Compare the result with the installer entry in SHA256SUMS.txt.
2. Run the installer and choose the installation folder and shortcuts you want.

The installer is per-user by default. Normal browsing, the native filesystem helper, Disk Map, indexing, previews, and file operations do not require the main application to run as administrator.

Windows SmartScreen Notice

The current public preview is not Authenticode-signed because a trusted production certificate is not yet available. Windows SmartScreen will identify it as an unrecognized app from an unknown publisher.

Download only from the official GitHub release, then verify the installer before deciding whether to continue:

Get-FileHash .\ExploreBetter-*-x64-setup.exe -Algorithm SHA256

Compare the result with SHA256SUMS.txt from the same release. Do not disable SmartScreen globally or install an untrusted root certificate. The project website keeps the current filename, checksum, and expected first-run warning together in one place.

Tagged builds produced by the repository release workflow also receive a GitHub build-provenance attestation. Provenance ties an artifact to its source workflow and commit; it improves traceability but does not replace Authenticode or remove the Windows warning.

Explorer Integration

Explorer replacement features are opt-in. On the first packaged launch, Explore Better offers to become the current user's default handler for normal filesystem folder and drive opens. Choosing Use Explore Better backs up the exact existing shell values, installs folder, drive, folder-background, and Open file location in Explore Better handlers, and leaves Windows Explorer installed.

You can make the same change later from Integrate > Make Default, add the optional Win+E sign-in helper, or choose Restore Previous to put the backed-up handlers back exactly as they were. Applications that ask Windows to open a folder normally can use Explore Better; applications that explicitly execute explorer.exe are hard-coded to Windows Explorer and cannot be redirected safely. Explore Better also works as a standalone file manager without changing any defaults.

When an older Explore Better release already owns the folder/drive default, current packaged builds automatically replace its legacy PowerShell command with the installed Explore Better.exe while preserving that choice. If another application owns the default, Explore Better repairs only its own existing context-menu commands and does not take the default back.

Feature Modules

Dual-Pane File Browser

• Independent left and right panes with tabs, tab history, locked tabs, and reopen/cycle shortcuts.
• Details, compact, and tile views with configurable columns and image thumbnails.
• Editable path bars, clickable breadcrumbs, aliases, recent paths, and folder suggestions.
• Text, kind, and label filters plus Explorer-style keyboard selection and find-as-you-type.
• Vertical, horizontal, and single-pane layouts with resizable Navigator, pane splitters, Preview, columns, and command dock.
• Linked Panes, Auto Refresh, hidden/system item controls, and reusable folder formats.

High-Performance Large Folders

• Progressive first paint instead of waiting for an entire directory to hydrate.
• Virtualized file lists that keep only a small visible row window in the DOM.
• Shared listing work for matching panes, cached metadata, bounded prefetching, and background hydration.
• An automatic foreground-activity coordinator pauses and aborts speculative work during navigation, search, analysis, file operations, or while the app is hidden, then resumes it without duplicating cached requests.
• Native Win32 enumeration for local folders with a Node fallback for unsupported paths and platforms.
• Persistent Speed Index and Background Index options for repeated searches.

The current 100,000-entry acceptance fixture records a 101.5 ms median first visible window, 616.7 ms median full hydration, and 47 rendered rows.

Transactional File Operations

• Copy, move, rename, bulk rename, transfer, sync, archive, recycle, app trash, and permanent delete.
• Conflict previews with rename, overwrite, and skip policies before files are changed.
• Destination-volume staging and overwrite backups for recoverable commits.
• Operation queue with progress, transfer rate, ETA, pause, resume, cancel, retry, and undo metadata.
• A bounded chronological timeline records queueing, phases, progress milestones, cancellation, retry, Undo, recovery, and completion, with related operations linked in both directions.
• Startup reconciliation for interrupted operations and cross-volume moves awaiting source removal.
• Protection against drive-root deletion, app-state deletion, recursive source/destination mistakes, and stale destructive previews.

Disk Map And Size Analyzer

• Full-window hierarchical treemap for understanding where disk space is used.
• Nested folder and file rectangles with drill-down, breadcrumbs, Root, Up, Focus, and Open actions.
• Logical-size and allocated-size modes with clearly labelled accuracy information.
• Color by file type or stable top-folder branch.
• Top folders, files, extensions, and type-category summaries.
• Warm scan caching, cancellation, operation invalidation, and keyboard navigation.
• Exact local Windows allocation data through GetCompressedFileSizeW and volume geometry.

Search, Indexing, And Cleanup

• Bounded recursive filename and text-content search.
• Filters for kind, size, timestamps, and Windows attributes.
• Warm-cache search across saved background-index roots.
• Flat View for recursively presenting a folder as one virtual pane.
• Duplicate Finder with same-size grouping and optional SHA-256 confirmation.
• Checksum manifest creation and verification with SHA-256, SHA-1, or MD5.
• Folder-size calculation directly inside normal file panes.

Compare And Synchronize

• Left/right folder comparison with left-only, right-only, newer, different, and type-mismatch states.
• Top-level or recursive comparison.
• Explicit left-to-right and right-to-left sync plans.
• Reusable Sync Profiles for folder pairs and policies.
• Optional mirror cleanup through recoverable App Trash moves.
• Preview tokens that reject an apply if the filesystem changed after planning.

Organization And Workspaces

• A compact Pinned section presents Favorites and path aliases together without merging their persisted models, followed by the primary Folder Tree, meaningful connected Devices, Quick Access, Drives, and up to eight Recent locations with an explicit show-all control.
• Named layouts that restore panes, tabs, filters, sorting, view modes, and panel sizes.
• Folder Tab Groups, File Collections, Selection Sets, and Pane Snapshots.
• File Basket for gathering paths from multiple locations before a batch action.
• Color labels and notes that follow app-managed rename, copy, and move operations.
• Folder Formats, Display Presets, and Filter Presets.
• Exportable configuration backups for workspace and automation settings.

Preview, Viewer, And Quick Edit

• Built-in previews for folders, text, images, PDFs, audio, video, STL meshes, and STEP/STP CAD models.
• Interactive local 3D viewing with orbit, pan, wheel or button zoom, fit, isometric/front/top views, edges, dimensions, mesh counts, and triangle counts. STEP tessellation runs in a dedicated local OpenCascade worker and never uploads model data.
• Larger Viewer with neighboring-file navigation and a filmstrip.
• Quick Edit for small text files with an undoable save operation.
• Properties and Path Health views with sizes, timestamps, hashes, drive information, and bounded diagnostics.
• Native Windows Properties and Reveal in Explorer handoff when needed.

Command Center And Automation

• Searchable command palette with fuzzy matching, pins, history, and hotkey badges.
• Every command identifies whether it stays in Explore Better, requests File Explorer, launches an external app, or opens a Windows dialog, and explains the expected result.
• The Electron title bar stays on one 44 px row from 390 through 1920 px; measured overflow collapses labels and moves Focus, Operations, then Disk Map into a keyboard-accessible More menu before Search or Command.
• Custom command dock profiles for frequently used actions.
• Saved trusted PowerShell or Command Prompt tools with captured output.
• Saved trusted scripts with a bounded file-management API.
• Custom app-level hotkeys for built-in actions, tools, and scripts.
• Open With presets and extension-matched quick launchers.

Per-Tab Integrated Terminals

• One lazy ConPTY terminal for every file tab, rendered with xterm.js in a resizable drawer below its pane.
• Independent left and right terminals that stay alive, retain output, and return with their tab while the app is open.
• PowerShell 7 discovery with Windows PowerShell and Command Prompt fallb
