Changelog

What’s New

• New “Move to Archive…” action — pick any folder and DuoBolt moves selected duplicates there with their directory structure preserved, instead of sending them to the Trash. Archives appear in Deletion History with a “Review Archive” page to restore from.
• New “Exclude archive folders from scans” setting (on by default) keeps archived duplicates out of future scans. Scan Setup also highlights any selected folders that overlap with known archives.
• macOS scans now detect APFS clone groups — files that share storage on disk (e.g., from cp, Time Machine snapshots, build caches) — so DuoBolt no longer counts them as recoverable space. Toggleable via Advanced → Performance options, on by default.
• Selection size, the Review screen total, the master-folder-rule preview, and delete confirmations all use the new clone-aware accounting, so the bytes you see before clicking “Delete” match what your disk actually frees.
• Deletion History distinguishes “freed” (deletes) from “archived” (archives), since archived files still occupy real space at their destination volume.

Improvements

• Scan Results header, sort order, and per-group display now show “recoverable” alongside “total” when APFS clones are detected, making it clear which groups actually free space when removed.
• Scan-button accent in the Setup screen now uses the app’s semantic gradient for better visual consistency.
• On non-APFS volumes (Windows, Linux, HFS+, SMB) clone detection is a no-op — behavior is unchanged.

Fixes

• Deletions and archives performed after restoring scan results from a previous session (e.g., closing and reopening the app) now record correctly in Deletion History.

Improvements

• Modernized the internal build system and refreshed the auto-update component for improved reliability when checking for and installing updates.

Improvements

• Small visual polish in the Review screen
• The Scan Results screen now follows the same back-button navigation pattern used throughout the app, making it more intuitive to move between screens
• Tapping a category on the Dashboard and jumping into Deletion History now clears any previous date filter, so you always start with a fresh view

Fixes

• Fixed Deletion History showing a blank “No deletions yet” screen when deletions existed outside the default date range. The date and file-type filter bar now stays visible so you can switch to a wider range and find older entries.

Improvements

• Refined Dashboard and Deletion History layouts for better use of space and more consistent sizing
• Improved compact-window behavior across stats cards, filters, and history surfaces
• Cleaned up internal desktop dependencies and related integration details for a leaner build

What’s New

• After removing duplicates, DuoBolt can now automatically clean up folders that become empty as a result. Enable the new toggle in the Review screen before deleting to activate this behavior.

Improvements

• Improved Scan Setup drag-and-drop reliability and added clearer feedback when dropping unsupported items
• Refined Scan Setup messaging with inline status/error feedback and updated notification styling for better clarity
• Improved Deletion History filter behavior and empty/loading states for more consistent results feedback

• Refined preview stage behavior across audio/video transitions with smoother resizing and better aspect-ratio handling
• Reduced visual flicker during media switching and tightened playback-state handling around completion/replay
• Improved keyboard interaction scoping in the preview dialog to prevent background view key handling

Improvements

Improvements

• Navigation is now faster with keyboard shortcuts: Cmd/Ctrl+1 (Dashboard), Cmd/Ctrl+2 (Scan), Cmd/Ctrl+3 (Settings)
• Added Cmd/Ctrl+Enter to start scanning from Scan Setup, plus shortcut tooltips
• Improved Deletion History filters so they are clearer and easier to use
• Deletion History now opens by default with Last 30 days
• Updated date wording to Last 12 months to avoid confusion

Fixes

• Fixed several visual glitches in Deletion History (sticky headers, spacing, and filter reset behavior)
• Improved dark-mode category colors for better readability
• Disabled controls now show the correct cursor state (no more click cursor on inactive buttons)
• Fixed Scan Results footer behavior when using Master folders with zero selected files
• Improved Master-folder chips, including clearer remove (X) interaction and better hover feedback
• Fixed Scan statistics so “Files Cached” and “Data Cached” are hidden when cache hits are zero

Improvements

• Closing the app from Scan Results now offers a clear Save & Exit flow for keeping your current session
• Added resume-on-launch for saved Scan Results sessions, including restored filters, sorting, selection, and expanded groups

Improvements

• Scan Review now handles very large selections more smoothly, including faster expand/collapse and less jank while navigating big trees
• Restore Deleted now scrolls and updates selection state much more smoothly on large history entries
• Native file icons now load more consistently in large lists thanks to smarter app-side caching and controlled request concurrency (with the biggest gains on Windows)
• On macOS, window dragging is now limited to the active screen header area to prevent accidental drags while interacting with controls
• Additional native icon pipeline tuning on Windows improves stability under heavy UI load
• Deletion History now collapses repeated identical deletion runs into a single entry with a “Repeated xN” badge, keeping the newest run visible first

Fixes

• Fixed an overlap in Scan Setup where the Selected folders scrollbar could cover Remove folder buttons
• Fixed bucketed Scan Results so the first group in each bucket gets the correct top corner radius when expanded
• Fixed Bulk Select “Clear selection” to respect the active filtered view instead of clearing unrelated selections
• Fixed Deletion History sticky section headers so the first sticky header renders with the same translucent background as the rest
• Fixed deletion flow totals and per-type breakdown so file counts and size totals stay accurate during and after deletion
• Fixed trash deletion progress reporting so long multi-file deletes advance progressively instead of appearing stuck at 0% and then jumping to 100%

Improvements

• Scan Results scrolling is now significantly smoother on very large datasets
• Scan Progress now shows cache usage in real time (Files Cached and Data Cached)
• Search and filtering remain more responsive with large result sets

Fixes

• Reduced UI stalls when rapidly scrolling or jumping within long Scan Results lists

Improvements

• The default window size on Windows now compensates for title bar and border chrome, so the usable area matches macOS exactly

Fixes

• Simple scan mode now respects the “Default minimum file size” setting from Settings instead of always using 1 MiB
• Changing the default minimum file size in Settings is immediately reflected in Simple mode without needing to switch modes
• The Deletion History filter bar no longer disappears when a date filter (e.g. “Today”) produces no results
