FileSearch 1.8.0.0

What's Changed

Outlook mail search

• Added native content search for .msg messages and local .pst / .ost mail stores without requiring Outlook or an Outlook IFilter.
• Search message subjects, senders, recipients, body text, attachment names, and mail folders through live content searches, folder content indexes, Quick Search's indexed-content option, and CLI searches.
• Added individual message result cards, sender/date/folder metadata, message-specific previews, and mail metadata in CLI exports. PST/OST messages can be opened as text-only EML copies in the registered mail application.

Mail search reads local files and cached OST messages. It does not search attachment contents or synchronize online mailboxes. Changed PST/OST stores are re-extracted as a whole; close Outlook or use a stable copy for busy stores. See the mail search guide for coverage and limits.

Whole-drive NTFS file-name indexing

• Added an optional file and folder name index for local NTFS drives, built through a fast administrator-assisted master file table scan or an unprivileged file-ID folder scan.
• Keep indexed names current through the NTFS USN change journal, with saved snapshots and rebuild handling when journal checkpoints are no longer available.
• Integrated drive indexes with Quick Search and indexed file/folder name searches in the main window and CLI.
• Added drive-index settings and status controls, plus volumes list, volumes build, volumes search, and volumes remove CLI commands.

Search interface and performance

• Redesigned the search bar, toolbar, collapsible sidebar, grouped result cards, preview pane, and status area. Added persisted sidebar state and improved match navigation.
• Improved typing, filtering, scrolling, and result display for large result sets through virtualized grouped lists and batched result delivery.
• Prevented stale Quick Search results from replacing newer searches and moved file metadata loading off the UI thread.

Documentation and maintenance

• Updated bundled HTML help to match the current interface, indexing options, Quick Search, result previews, CLI commands, and workflows.
• Added Outlook mail-search help and a local ONNX Smart Search walkthrough, covering compatible model packs, vector indexing, semantic: queries, and current limitations.
• Updated index storage for large file sizes and NTFS journal positions, with an in-place upgrade for existing schema-26 databases.
• Aligned application binary versions with release package versions and included mail-reader licenses and third-party notices in the packages.
• Updated application and test dependencies, including ONNX Runtime 1.30.0, CSharpDB.Engine 4.6.4, and WebView2. Includes the dependency update by @dependabot[bot] in #13.

Validation

• Local Debug and Release suites each passed all 805 tests, with no failures or skipped tests; Debug coverage was collected.
• GitHub CI and the release workflow passed, including release validation, portable ZIP and MSI packaging, and published sidecar smoke tests.
