Features

• Adds a Folder File Filter action to file context menus in Explorer.
• Adds Folder File Filter: Open Settings to the Command Palette.
• Prompts for a glob mask such as **/*.md, **/*.json, **/*.test.ts, **/*.log, or **/*.png.
• Shows matching files from the selected source folder as clickable tree items.
• Can infer one filter from multiple selected files, such as {*.json,*.md}.

Use

1. Open a workspace in VS Code.
2. Right-click a folder in Explorer.
3. Run Folder File Filter: Show Matching Files.
4. Enter a glob mask.
5. Open files from the Folder File Filter view.

For files, right-click a file in Explorer and run Folder File Filter. The command searches the selected file's parent folder using a mask inferred from the file name, such as *.json for settings.json. If several files are selected with Ctrl or Shift, the command combines their unique masks, such as {*.json,*.md}.

To open extension settings, run Folder File Filter: Open Settings from the Command Palette.

Settings

{
  "folderFileFilter.defaultMask": "**/*",
  "folderFileFilter.maxResults": 500,
  "folderFileFilter.openOnSelection": false,
  "folderFileFilter.autoFilterFilesFromSelectedFile": true,
  "folderFileFilter.autoFilterFromActiveFile": true,
  "folderFileFilter.restoreFocusAfterOpenDelayMs": 150
}

Enable folderFileFilter.openOnSelection to open the highlighted result while moving through the list with Up/Down. Files open with their default editor in preview mode and focus stays in the Folder File Filter view. Disable folderFileFilter.autoFilterFilesFromSelectedFile to confirm or edit the inferred mask before the file context menu command runs. Disable folderFileFilter.autoFilterFromActiveFile if opening a file in the editor should not update the active filter automatically. Increase folderFileFilter.restoreFocusAfterOpenDelayMs if a custom editor takes focus after opening and interrupts Up/Down navigation.
