如何在 Windows 上預覽 PDF 檔案

無需打開完整閱讀器，在 Windows 檔案總管中快速查看 PDF 檔案的方法。

How to preview PDF files in Windows Explorer

The built-in options on Windows are limited and often depend on the app installed on the machine. If your goal is fast triage in File Explorer, a dedicated preview tool keeps you closer to the folder workflow instead of bouncing between Explorer and a separate PDF application.

Why opening a full PDF app is slower for triage

When you are checking filenames, verifying contents, or finding the right attachment, the overhead comes from context switching. Full readers are useful for deep reading, but they are slower when your job is to decide which file to open next.

Seer 如何適配此工作流程

Seer 為 PDF 和其他常見檔案類型增加了空白鍵即時預覽功能，這樣您可以直接在 Windows 檔案總管中查看檔案。這讓您可以更快速地檢查資料夾、對比相似文件，並將注意力集中在檔案篩選上，而非應用程式管理。
