建立和填入資料夾

資料夾是只包含中繼資料的檔案，可用於整理 Google 雲端硬碟中的檔案。這些屬性如下：

  • 資料夾是具有 MIME 類型 application/vnd.google-apps.folder 的檔案，且沒有副檔名。
  • 別名 root 可用於參照提供檔案 ID 的任何根目錄。

如要進一步瞭解雲端硬碟資料夾限制，請參閱「檔案和資料夾限制」。

本指南說明如何執行一些與資料夾相關的基本工作。

建立資料夾

如要建立資料夾，請使用 files.create 方法，搭配 application/vnd.google-apps.folder MIME 類型和標題。以下程式碼範例顯示如何使用用戶端程式庫建立資料夾：

在特定資料夾中建立檔案

如要在特定資料夾中建立檔案，請使用 files.create 方法，並在檔案的 parents 屬性中指定資料夾 ID。

parents 屬性會保留含有檔案的父項資料夾 ID。在頂層資料夾或任何其他資料夾中建立檔案時，可以使用 parents 屬性。

檔案只能有一個父項資料夾，系統不支援指定多個父項。

在不同資料夾之間移動檔案

如要移動檔案，您必須更新 parents 屬性的 ID。

如要為現有檔案新增或移除父項，請使用 files.update 方法，並搭配 addParents 和 removeParents 查詢參數。

檔案只能有一個父項資料夾，系統不支援指定多個父項。

檔案和資料夾限制

雲端硬碟檔案和資料夾有一定的儲存空間限制。

使用者項目限制

每位使用者最多可擁有 5 億個帳戶建立的項目。達到上限後，使用者就無法在雲端硬碟中建立或上傳項目，但依然可以查看及編輯現有項目。如要再次建立檔案，使用者必須永久刪除項目，或使用其他帳戶。詳情請參閱「將檔案和資料夾移至垃圾桶或刪除」。

計入此項限制的物件如下：

  • 使用者在雲端硬碟中建立或上傳的項目
  • 使用者建立，但現在由他人擁有的項目
  • 垃圾桶中的項目
  • 捷徑
  • 第三方捷徑

不會計入這項限制的物件包括：

  • 已永久刪除的項目
  • 他人建立但與使用者共用的項目
  • 他人建立但由使用者擁有的項目

嘗試新增超過 5 億個項目時，系統會傳回 activeItemCreationLimitExceeded HTTP 狀態碼回應。

請注意，雖然服務帳戶可擁有的項目數量沒有限制，但服務帳戶可建立的項目數量上限為 5 億個。

資料夾項目限制

使用者「我的雲端硬碟」中的每個資料夾最多只能包含 500,000 個項目。這項限制不適用於「我的雲端硬碟」根資料夾。計入此項限制的項目如下：

如要進一步瞭解資料夾限制，請參閱「Google 雲端硬碟中的資料夾限制」。

資料夾深度限制

使用者的「我的雲端硬碟」最多只能包含 100 層巢狀資料夾。也就是說，子資料夾無法儲存在深度超過 99 層的資料夾下。這項限制僅適用於子資料夾。子檔案的 MIME 類型如果不是 application/vnd.google-apps.folder，就不會受到這項限制。

如下圖所示，您可以將新的資料夾置於資料夾巢狀結構中，可放到第 99 層資料夾，但無法放到第 100 層資料夾中。不過，第 100 層資料夾可以儲存檔案，就像儲存其他雲端硬碟資料夾一樣：

雲端硬碟資料夾階層深度限制。

嘗試新增超過 100 個層級的資料夾時，系統會傳回 myDriveHierarchyDepthLimitExceeded HTTP 狀態碼回應。
