创建和填充文件夹

文件夹是仅包含元数据的文件，可用于整理文件。它们具有以下属性：

文件夹是具有 MIME 类型的文件 application/vnd.google-apps.folder，且无扩展名。
别名 root 可用于在文件 ID 任意位置引用根文件夹。。

要详细了解云端硬盘文件夹限制，请参阅文件和文件夹文件夹限制。

本指南介绍如何执行一些与文件夹相关的基本任务。

创建文件夹

如需创建文件夹，请使用 files.create 包含 application/vnd.google-apps.folder MIME 的方法类型和标题。以下代码示例展示了如何使用客户端库创建文件夹：

在特定文件夹中创建文件

如需在特定文件夹中创建文件，请使用 files.create 方法，并在 parents 属性。

parents 属性包含包含该文件的父文件夹的 ID。在顶级文件夹中创建文件时，可以使用 parents 属性；或者任何其他文件夹中

一个文件只能有一个父级文件夹；指定多个父项支持。

在文件夹之间移动文件

如需移动文件，您必须更新 parents 属性的 ID。

如需为现有文件添加或移除父级，请将 files.update 方法与 addParents 和 removeParents 查询参数。

一个文件只能有一个父级文件夹；指定多个父项支持。

文件和文件夹限制

云端硬盘文件和文件夹存在存储空间限制。

用户项限制

每个用户最多可以拥有由该账号创建的 5 亿件商品。达到上限后，该用户将无法再在以下位置创建或上传内容：云端硬盘。但他们仍然可以查看和编辑现有内容。要创建文件中，用户必须永久删除内容或使用其他账号。对于请参阅将文件移到回收站或删除文件文件夹。

占用此限额的对象包括：

用户在云端硬盘中创建或上传的内容
由用户创建但现在归他人所有的内容
回收站中的内容
快捷键
第三方快捷方式

不计入此限制的对象包括：

永久删除的内容
已与该用户共享但归他人所有的内容
归该用户所有但他人创建的内容

如果尝试添加的内容超过 5 亿，系统会返回 activeItemCreationLimitExceeded HTTP 状态代码响应。

请注意，虽然服务账号可以处理的项目数量那么 5 亿项内容限制适用于服务账号的内容数量创建的所有文件

文件夹项限制

在用户的“我的云端硬盘”中，每个文件夹中的内容数量上限为 50 万项。此限制不适用于“我的云端硬盘”的根文件夹。物品计入此限制的有：

文件夹
文件。所有文件类型，无论文件所有权如何。
快捷方式。计为文件夹中的一项内容，即使该内容在文件夹内不在该文件夹中。有关详情，请参阅创建指向云端硬盘文件的快捷方式。
第三方快捷方式。即使将它所指向的项不在此文件夹中。如需了解详情，请参阅为 app。

如需详细了解文件夹限制，请参阅文件夹限制 Google 云端硬盘。

文件夹深度限制

用户的“我的云端硬盘”中的嵌套层不得超过 100 层。文件夹中。也就是说，子文件夹不能存储在深度超过 99 层。此限制仅适用于子文件夹。孩子 MIME 类型不是 application/vnd.google-apps.folder 不受此限制的约束。

例如，在下图中，可以将新文件夹嵌套在文件夹内但不在编号为 100 的文件夹内。但是，编号为 100 的文件夹可以存储文件：

如果尝试添加超过 100 层的文件夹， myDriveHierarchyDepthLimitExceeded HTTP 状态代码响应。
