🚀 Version 1.20.26.917 (Latest Release)

🎬 All-in-One Multi-Media Folder Browsing (Photos + PDF + Novels + Manga + Videos)

• Unified Media Playlist for Mixed Folder Contents
  • Seamlessly browse photos, PDF documents, text novels (.txt), manga archives (.cbz, .zip), and videos (mp4, mkv, avi, wmv, mov, webm, flv, etc.) together in the folder playlist without separating file types.
  • Mini Media Badges on Thumbnail Ribbon: Distinctive color-coded badges (PDF red, TXT mint, CBZ purple, VIDEO blue) on the top-left of thumbnails for instant visual recognition.
  • One-Click / Enter to Read or Play:
    • PDF / TXT / CBZ: Press Enter, double-click the main view, or click the bottom action button ([ 📑 Read PDF (Enter) ], [ 📚 Read Novel (Enter) ], [ 📖 Open Manga (Enter) ]) to enter full dedicated reader mode immediately.
    • Video: Click the central circular play button (▶) or the bottom action button ([ ▶ Play Video (Enter) ]) to play in your system's default media player.
  • Smooth Parent Folder Return (Esc / Backspace):
    • Press Esc or Backspace inside full reader mode to seamlessly return to the exact file index in the parent folder's playlist.
  • Intelligent Archive (ZIP / CBZ) Content Differentiation:
    • If an archive contains no images, it specifically displays "⚠️ No images found in the archive" instead of the generic "Unsupported format or corrupted file".
    • Corrupted archive files are distinctly diagnosed and flagged with "The archive file is corrupted or cannot be opened".
    • Instant toast notifications are also provided when attempting to open or press Enter on non-image archives.
  • Media Filter Preference (Settings F2 ➔ General):
    • Choose between [ All Media (Photos/PDF/Manga/Novels/Videos) ] and [ Photos Only ] anytime.

🎨 Full Native Support for Photoshop Large Document Format (PSB)

• Photoshop Big (.psb) File Support
  • Added 100% native Delphi support for Adobe Photoshop Large Document Format (.psb) files up to 300,000 pixels without any external DLLs or third-party dependencies.
  • Safe Hardware Texture Clamping: Massive images exceeding Direct2D GPU limits (16,000px) are smoothly downscaled to guarantee stable, crash-free hardware-accelerated rendering.
  • Fast Thumbnail Extraction & Seamless Integration: Full support across folder navigation, bottom thumbnail ribbon, file open dialogs (*.psb), and Windows file association settings.

🔒 Password-Protected PDF Detection & Contextual Boundary Navigation

• Intelligent Password-Protected PDF Detection & Dedicated UI
  • Replaced the confusing and harsh "Unsupported format or corrupted file" error message for encrypted PDFs with "🔒 Password-protected PDF document".
  • Implemented an ultra-lightweight trailer inspection (IsPdfPasswordProtected) to detect encryption within milliseconds.
  • Added a dedicated bottom action button [ 🔒 Open with Default App (Enter) ], enabling users to press Enter or click to immediately launch their default system PDF viewer (Acrobat Reader, Edge, etc.) and enter their credentials.
• Contextual Boundary Navigation Toasts for Documents & Media
  • Eliminated awkward "last folder" toasts when reaching the end of PDF pages or novels:
    • PDF Documents: "This is the last page", "This is the last document" (when no more PDFs exist), and "▶ Next Document: ..." when advancing.
    • Text Novels (.txt): "This is the last page", "This is the last volume", and "▶ Next Volume: ...".
    • Comic Archives (.cbz/.zip): "This is the last chapter/volume", and "▶ Next Chapter: ...".
    • Photo Folders: "Last file reached", and "▶ Next Folder: ...".

⚙️ Configurable Boundary Navigation & Dynamic File Version

• Custom End-of-List Action (Settings F2 ➔ Manga / Navigation)
  • Customize what happens when reaching the first or last item in a folder/archive:
    • Stop (Notify): Toast notification without moving.
    • Loop (Repeat): Wrap around from last to first (or first to last).
    • Prompt (Default): Confirmation modal before moving to the adjacent folder.
    • Auto Advance: Continuously and automatically advance to next/previous chapters.
• Real-Time App File Version in About Screen
  • The About dialog now dynamically queries and displays the actual executable's file version (FileVersion) in real-time instead of hardcoded strings.

  • Directly extracts the high-resolution canvas preview from Clip Studio .clip project files, allowing digital artists and webtoon creators to view artwork instantly.

⚡ Remarkable Responsiveness & Optimized Image Loading

• Zero Ghosting Between Image Transitions
  • Immediately unloads active bitmap resources and clears the render target to background color upon loading requests, completely eliminating border fragments or aspect-ratio ghosts when switching images.
• Progressive Loading & Smooth Spinner Indicator
  • Decoding massive files no longer causes freezes or blank screens; NZView displays a preview thumbnail placeholder immediately, followed by a smooth rotating spinner while full-fidelity data loads.
• Enhanced Unsupported / Corrupted File Diagnostics
  • When encountering an unreadable or damaged file, NZView now presents a clear, friendly notification centered on screen: "Unsupported format or corrupted file".
• Near-Instant 0.02s Reopening for Large Files
  • Multi-hundred megabyte images are retained in high-speed cache after initial decode, allowing near-instantaneous reopening with zero lag.
• Main Photo Priority Loading (No Filmstrip Blocking)
  • Filmstrip background thumbnails no longer compete with main view rendering; the image you select always receives top priority.
• Fluid 0s Navigation Back and Forth
  • Returning to recently viewed photos is instant and completely fluid without re-decoding.
• Smooth Filmstrip Scrolling
  • Large images and special format thumbnails are cached on disk, ensuring buttery-smooth scrolling along the bottom thumbnail bar.

🛠️ Hardware-Tailored [System] Settings (F2) & Architecture Upgrades

• [System] Settings Tab with Modern Dark Segmented Pill Buttons
  • Sleek Direct2D touch- and click-friendly pill controls replacing standard Windows dropdowns:
    • Preload Worker Threads: Choose [ Auto (Recommended) ] / [ 2 Cores ] / [ 4 Cores ] / [ 8 Cores ] according to your CPU.
    • RAM Cache Budget: Allocate memory limits [ 512 MB ] / [ 1 GB ] / [ 2 GB ] / [ 4 GB ] matching your hardware specs.
    • Large Image Decode Strategy: Toggle between [ Screen Fit (Fast) ] and [ Full Resolution ].
    • Disk Cache & One-Click Purge: Enable special format thumbnail caching on disk, and easily clear accumulated cache files with a single click.
• True Portable Mode (portable.dat) & Clean Directory Separation
  • Portable Mode: Detects portable.dat in the executable folder to run completely standalone from USB or external drives with zero footprint on host Windows registry or folders.
  • Standard Installer Separation: Application binaries reside safely in Program Files, user configuration (Config.ini, Language\) resides in %APPDATA%\NZTools\NZVIEW, and high-volume disk caches/logs reside in %LOCALAPPDATA%\NZTools\NZVIEW to ensure zero UAC permission conflicts.
• Clean Multi-Language Architecture (Built-In KO/EN + External INI Packs)
  • Korean and English are built directly into the core engine for guaranteed fallback, while Japanese, Chinese, and community languages are loaded externally from the Language\ directory.
  • Fully normalized with 8 sections, 184 keys, 100% parity, and UTF-8 with BOM standard encoding.
• End-of-List Navigation Action Option (Settings F2 ➔ Comic Tab)
  • Added 4 selectable actions when reaching the beginning or end of a photo list / chapter:
    • Stop (Show Notice): Halts navigation and displays a friendly toast notification ("This is the first/last file").
    • Loop: Seamlessly cycles from last file to first, or first file to last in an infinite loop.
    • Confirm Next List: Traditional prompt card asking whether to open the next/previous folder or archive.
    • Auto Advance: Instantly and automatically transitions to the next/previous folder or volume with 0s delay.
• Dynamic Real-Time File Version Display in About Screen
  • Replaced static placeholder text with real-time dynamic query of the active binary's actual file version (NZView v1.20.26.915).
