XMP Remover：大量刪除PDF 文檔的XMP data

應客戶的要求，利用Acrobat API寫了一個大量刪除PDF 文檔中XMP的小工具。

Acrobat 支援刪除XMP資訊，但必須一個節點一個節點刪除，一個檔案一個檔案刪除，非常麻煩，利用XMP Remover可以可以快速刪除指定目錄下所有PDF 文檔的XMP資訊。

P.S.

Adobe XMP（可擴充中繼資料平台，Adobe's Extensible Metadata Platform）是一種標籤技術，可以協助使用者將檔案資訊(中繼資料）添加到以 PNG、GIF、JPEG、Photoshop、TIFF 和PDF等格式儲存的檔案中。XMP 為 Adobe 應用程式間的中繼資料交換提供了便利。例如，使用者可以將一個檔案中的中繼資料另存新檔模板，然後將中繼資料匯入到其它檔案中。 主要用於工作流程中重要訊息的傳遞工作。

Adobe's Extensible Metadata Platform (XMP) is a labeling technology
that allows you to embed data about a file, known as metadata, into the
file itself. With XMP, desktop applications and back-end publishing
systems gain a common method for capturing, sharing, and leveraging
this valuable metadata — opening the door for more efficient job
processing, workflow automation, and rights management, among many
other possibilities. With XMP, Adobe has taken the "heavy lifting" out
of metadata integration, offering content creators an easy way to embed
meaningful information about their projects and providing industry
partners with standards-based building blocks to develop optimized
workflow solutions.
