Grab All Files v4.5.6 — 変更点

・Liferay ドキュメントポータルの拡張子なしダウンロードリンク（東京海上 hoken-gw.net AGTHWY 等）を検知
・classic ASP/JSP の「ダウンロードスクリプト」エンドポイント（アフラック CyberCampus downloadContFile.asp?prm1=… 等）を「このページのみ」で検知
・Edge の IE モード検出時に「Chrome 等で開き直して再スキャン」を非ブロッキング警告バナーで明示

Maintenance update.
• Quick-select buttons in the results bar now appear only for file
types actually found on the page (no more unresponsive
"Video"/"Audio" buttons when none were detected).
• More accurate file-type detection plus several reliability and
stability fixes.

v4.5.2 fixes 26 confirmed bugs from a comprehensive audit:

Critical fixes:
- Fixed filename truncation bug that dropped file extensions on long titles
- Fixed crawl deduplication to preserve dynamic URLs with tracking parameters (ref, spm, ocid)
- Fixed blob storage timeout that caused ZIP/merge downloads to hang indefinitely

Other improvements:
- Enhanced download queue stability and reliability
- Added "Session Protection Mode" to prevent logout during scans on login-required portals
- Fixed accessibility issues (aria-live regions, dialog focus management)
- Clarified hover tooltips across all features
- Fixed UI layout issues in the filter panel

Grab All Files 4.5.0

New & improved
• Much deeper website scanning — finds far more pages on large sites:
- Reads sitemap.xml / robots.txt to reach pages that aren't linked anywhere in the page's HTML.
- Follows navigation hidden in JavaScript (javascript: links and onclick handlers), <frameset>/<frame>, and image-map <area> links.
- Follows GET search/pagination forms, meta-refresh redirects, Turbo Frames, Speculation Rules, htmx/Unpoly actions, and SPA router links (Angular / Vue / Nuxt).
- Follows dynamic navigation links (.php / .asp / .jsp …) and extension-less file links marked only by an icon (e.g. "icon-pdf").
- "This page and linked pages" (depth ≥ 1) now always includes everything found by "This page only".
• Smarter file names for exam past-papers and similar sites: builds names like School_Year_Subject_Type.pdf from the page structure instead of every link becoming the same "問題.pdf". Also decodes garbled PDF titles and trims "Microsoft Word - …" prefixes.
• New "Sequential numbering" download option (0001_, 0002_ …) to keep files in list order.
• Cleaner results and download bar: full-width Download / ZIP / Merge-PDF buttons and pill-style toggles.
• More reliable downloads on paid / signed-URL sites: short-lived links are downloaded first, with a clear "link expired — please rescan" message instead of a silent failure.

Fixes
• Files served via CDNs/WAFs that answer HEAD with 403 but GET with 200 are no longer wrongly shown as "unavailable" (the scanner now falls back to a small ranged GET).
• Re-clicking the toolbar icon now immediately syncs the "This Page" URL to the active tab.
