Windows “Open in → File Explorer” launches Explorer directly, bypassing the user's default folder handler. File reveal also misses Directory Opus when it registers its default verb under Folder\shell rather than Directory\shell.

Open Windows paths with Invoke-Item -LiteralPath through the existing encoded PowerShell launcher. For reveal, inspect the applicable Directory or Drive class plus Folder, excluding Explorer's own executable and shell delegate before choosing the existing shell-open-parent fallback. With no replacement handler, retain Explorer's /select behavior. Keep native PowerShell attached, as required by the existing Windows launcher, and leave plain WSL opens and non-Windows launch paths unchanged. Escape PowerShell's typographic apostrophes as well as ASCII apostrophes.

Fixes #17323. This qualifies for the small, focused obvious-bug exception in CONTRIBUTING.md: it corrects the existing file-manager action to honor Windows folder associations, with no new setting, UI, or workflow.

Verification on Windows 11, against main 15fe28327278:

  • Traced the project OpenInPicker request through shell.openInEditor to ExternalLauncher.launchEditor: plain open omits reveal and previously spawned explorer directly. The desktop shell is not involved in this action. File-reference/context-menu reveals use the same server service with reveal: true.
  • Read the real registry without changes: HKCR\Directory\shell = none, HKCR\Drive\shell = none, HKCR\Folder\shell = openindopus; the latter resolves to Directory Opus's dopusrt.exe.
  • Executed the generated reveal script against those real registry values, replacing only the launch functions with transcript output. Before: Direct executable: explorer.exe /select,"C:\repo\file.txt". After: ShellExecute parent: C:\repo. No user windows were opened or closed.
  • Added regressions to the existing launcher test file. Before the original fix: three failures (plain folder open, Drive replacement, Folder replacement); stock Explorer selection and Directory replacement passed. Review follow-ups reproduced and fixed typographic-quote handling and two reveal edge cases: Explorer's explicit open handler and a drive-only replacement affecting ordinary folders. Windows tests execute the generated PowerShell with launch stubs, checking path escaping, command-like text as literal data, Explorer executable/delegate defaults, custom open handlers, and drive roots without opening windows. The final launcher test file reports 20 passed, 14 platform skips.
  • vp run check:changed --concurrency 1: format, lint, both knip passes, GraphQL check, affected typechecks (server, scripts, evals), and adjacent tests passed. Focused vp lint also passed.

WSL/Linux/macOS runtime checks and a packaged desktop UI run were not performed on this Windows host. The WSL UNC-path test expectation was updated for the shared reveal script; existing platform skips remain in place. No UI or contract changes.

Pprov3ntus11d ago

Confirmed on Windows PowerShell 5.1: the added regression failed with typographic apostrophes in the folder name. Updated the shared literal helper to double all PowerShell single-quote delimiters (ASCII plus U+2018 through U+201B). The Windows test now executes the generated source with a stub shell handler and verifies the exact path, including each typographic delimiter and harmless command-like text, arrives unchanged. UTF-8 output is explicit so Windows console encoding cannot conceal a path change. The focused tests and check:changed validation pass with this correction.

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Windows file-manager actions now honor registered replacement handlers, changing existing launch and reveal behavior. Human confirmation is required for that default change, and the unresolved PowerShell command-execution finding remains independently blocking.

Walkthrough

Windows folder launches now use PowerShell Invoke-Item with a normalized path. File reveal checks the Directory, Drive, and Folder shell registrations before falling back to Explorer selection.

Changes: Windows file-manager launch

Layer / File(s)Summary
Shell-based folder launch
apps/server/src/process/externalLauncher.ts, apps/server/src/process/externalLauncher.test.ts		Windows file-manager launches invoke normalized paths through PowerShell. PowerShell string escaping now doubles ASCII and typographic apostrophes. Windows tests cover folder launches and paths with special characters.
File reveal registration checks
apps/server/src/process/externalLauncher.ts, apps/server/src/process/externalLauncher.test.ts		File reveal checks Directory, Drive, and Folder registrations before using Explorer’s /select fallback. Tests cover the registration values and the updated WSL command expectation.

Explanation

[#17323] requires Windows folder opens to use the default folder handler instead of launching Explorer directly. On win32, resolveEditorLaunch now runs Invoke-Item -LiteralPath through the existing PowerShell launcher. Reveal handling checks the applicable Directory or Drive class and Folder, excludes Explorer handlers, and retains Explorer /select when no replacement handler exists. The added Windows tests cover folder opens, replacement handlers, Explorer defaults, drive roots, literal path escaping, and command-like path text. Non-Windows and plain WSL launch paths remain unchanged.

Full details: Out of Scope Changes check

Explanation

The changes remain within [#17323]. The reveal registry logic supports the same default-folder-handler behavior for file reveal. The PowerShell escaping change protects the new literal-path commands, including typographic apostrophes. The tests validate these changes, and the WSL expectation changes only for the shared reveal script. No unrelated UI, setting, contract, or platform workflow change is present.

Do not treat Explorer’s open verb as a replacement handler.

If Directory\shell and Drive\shell are none but Folder\shell is open, $folderVerb is truthy. The script then opens the parent with Invoke-Item instead of using Explorer’s /select, so file reveal does not select the file. open is also a valid ordinary folder action; check the selected verb’s handler before classifying it as a replacement.

Do not apply the Drive class to ordinary file parents.

When revealing a file, parent is path.dirname(windowsTarget), so an ordinary file parent is not a drive root. The script currently checks Directory, Drive, and Folder. A non-none Drive default makes $folderVerb truthy, so Invoke-Item opens the parent folder and skips Explorer’s /select fallback. The target file is therefore not selected. Check Drive only when parent is a drive root; otherwise check Directory and Folder.

✅ Confirmed as addressed by @prov3ntus

Pprov3ntus11d ago

Confirmed both findings against the current script, with two failing regression cases before this correction. Reveal now checks Drive only for a drive-root parent and Directory otherwise, alongside Folder. It inspects the selected verb's command/delegate and excludes Explorer's own executable and shell delegate, so an ordinary open action retains /select while a custom open handler still works. Tests cover both stock Explorer handler forms, a custom open handler, drive-only registrations on ordinary folders, and drive-root replacements. The final changed-file checks pass, including format, lint, knip, affected typechecks, and adjacent tests.

CcoderabbitaiBot11d ago

@prov3ntus Thanks for fixing both findings. The supplied code limits Drive checks to drive-root parents and excludes Explorer’s own handlers. This preserves /select for stock Explorer while allowing custom open handlers. Your reported regression cases cover both findings.

Check the implicit open verb.

When Folder\shell has no default value, Windows can use its open verb. A replacement registered only under Folder\shell\open\command is therefore skipped, and reveal opens Explorer instead of the replacement. Resolve the effective verb, including implicit open, and test this registration. (learn.microsoft.com)

Honor Directory before falling back to Folder.

Windows resolves a file-system directory through the more-specific Directory association before Folder. When Directory selects Explorer and Folder selects a third-party handler, this pipeline still returns the Folder verb. Invoke-Item then opens the parent without /select, so the requested file is not selected.

Stop checking broader classes after the first usable default:
