The AppData folder includes application settings, files, and data unique to the applications on your Windows PC. The folder is hidden by default in Windows File Explorer and has three hidden sub-folders: Local, LocalLow, and Roaming.

AppData文件夹包含Windows PC上的应用程序专用的应用程序设置，文件和数据。 默认情况下，该文件夹在Windows File Explorer中处于隐藏状态，并且具有三个隐藏的子文件夹：Local，LocalLow和Roaming。

You won't use this folder very often, but this is where your important files reside. For example, your bookmarks, saved sessions, and so on.

您不会经常使用此文件夹，但这是重要文件所在的位置。 例如，您的书签，已保存的会话等。

In this guide, you will learn how to find, unhide, and access the AppData folder in Windows.

在本指南中，您将学习如何在Windows中查找，取消隐藏和访问AppData文件夹。

什么是AppData文件夹？ (What is the AppData Folder?)

Applications in windows often store their settings and temporary data in the AppData Folder. Each windows user account has its own AppData folder. As I mentioned earlier, there are three folders inside AppData - Local, LocalLow, and Roaming.

Windows中的应用程序通常将其设置和临时数据存储在AppData文件夹中。 每个Windows用户帐户都有其自己的AppData文件夹。 如前所述，AppData内部有三个文件夹-Local，LocalLow和Roaming。

The Local folder is used to store data that is specific to a single windows system, which means data is not synced between multiple PCs.

Local文件夹用于存储特定于单个Windows系统的数据，这意味着数据不会在多台PC之间同步。

The LocalLow folder is the same as the Local folder, except it is used by applications with low integrity that run with restricted security settings, for example, Mozilla Firefox in private mode.

LocalLow文件夹与Local文件夹相同，区别在于完整性低的应用程序使用受限的安全设置运行该应用程序，例如私有模式下的Mozilla Firefox。

The Roaming folder is used to store data that will be synced across multiple Windows systems. This is often used for storing settings like bookmarks, saved passwords, and so on.

漫游文件夹用于存储将在多个Windows系统之间同步的数据。 通常用于存储书签，已保存的密码等设置。

如何查看AppData文件夹 (How to View the AppData Folder)

There are two ways you can access the AppData folder. You can either access it manually or by using the "AppData" variable name.

您可以通过两种方式访问​​AppData文件夹。 您可以手动访问它，也可以使用“ AppData”变量名访问它。

You can view the AppData folder manually by going into your Users folder, which is there in the C drive. In my case, the path is C:\Users\ADMIN.

您可以进入C驱动器中的“用户”文件夹，手动查看AppData文件夹。 在我的情况下，路径为C:\Users\ADMIN 。

Next, go to the "View" tab at the top and check the "Hidden items" checkbox, as shown below:

接下来，转到顶部的“查看”标签，然后选中“隐藏的项目”复选框，如下所示：

Now you should be able to see the AppData folder in your User folder.

现在，您应该可以在用户文件夹中看到AppData文件夹。

You can also access the AppData folder directly using the AppData system variable. Search for "Run" in the windows search as shown below, or press the Windows + R button to open the Run App.

您还可以使用AppData系统变量直接访问AppData文件夹。 在Windows搜索中搜索“运行”，如下所示，或按Windows + R按钮打开运行应用程序。

In the run app text box, enter "%AppData%" and click OK. Windows will directly open up the Roaming folder which is inside the AppData folder.

在“运行应用程序”文本框中，输入“％AppData％”，然后单击“确定”。 Windows将直接打开AppData文件夹内的Roaming文件夹。

结语 (Wrap up)

After reading this guide, I hope you're able to find the AppData folder in your PC.

阅读本指南后，希望您能够在PC中找到AppData文件夹。

Typically, you won't have to worry about the data inside the AppData folder – that is why it is hidden by default. It is only used by application developers to store the necessary data required by the application.

通常，您不必担心AppData文件夹中的数据-这就是默认情况下隐藏数据的原因。 它仅由应用程序开发人员用来存储应用程序所需的必要数据。

Everyday Windows users will only need to access or view the AppData folder if they need to create a backup of their application data.

每天Windows用户仅在需要创建其应用程序数据的备份时才需要访问或查看AppData文件夹。
