建立及填入資料夾

資料夾只包含中繼資料，可用於整理 Google 雲端硬碟中的檔案。這些屬性包括：

  • 資料夾是 MIME 類型為 application/vnd.google-apps.folder 的檔案，且沒有副檔名。
  • 在提供檔案 ID 的任何位置，都可以使用別名 root 參照根資料夾。

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，並提供 application/vnd.google-apps.folder 的 mimeType 和 name。下列程式碼範例說明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。

檔案只能有一個上層資料夾。系統不支援指定多個父項。如果未指定 parents 欄位，檔案會直接放在使用者的「我的雲端硬碟」資料夾中。

檔案和資料夾限制

雲端硬碟檔案和資料夾的儲存空間設有上限。

使用者項目限制

每個使用者最多可以有 5 億個由該帳戶建立的項目。 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改用其他帳戶。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
  • 第三方快速鍵

不會計入這項限制的物件包括：

  • 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

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

請注意，服務帳戶無法擁有任何檔案。而是必須將檔案和資料夾上傳至共用雲端硬碟，或使用 OAuth 2.0 代表使用者上傳項目。

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：

  • 資料夾
  • 檔案。所有檔案類型，無論檔案擁有權為何。
  • 快速鍵。捷徑計為資料夾的單個項目，即使指向的項目不在該資料夾中也是如此。詳情請參閱「建立雲端硬碟檔案的捷徑」。
  • 第三方快速鍵。捷徑計為資料夾的單個項目，即使指向的項目不在該資料夾中也是如此。詳情請參閱「建立應用程式儲存內容的捷徑檔案」。

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，子資料夾不能儲存在超過 99 層的資料夾中。這項限制僅適用於子資料夾。如果子檔案的 MIME 類型不是 application/vnd.google-apps.folder，則不受這項限制。

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：

如果嘗試新增超過 100 層的資料夾，系統會傳回 myDriveHierarchyDepthLimitExceeded HTTP 狀態碼回應。
