当我们安装程序时，它可能会进入Program Files 文件夹或 Program Files x86 文件夹^{(Program Files folder or the Program Files x86 folder)}。你们中的许多人可能都知道这个事实。每个程序都有一些自定义功能。当我们运行程序时，我们会更改其设置、自定义其界面（如果该功能可用）等。这些数据也存储在我们计算机的硬盘上，位于AppData 文件夹^{(AppData folder)}中。在本文中，我们将详细讨论AppData文件夹。

AppData 文件夹在哪里？

默认情况下，AppData文件夹隐藏在Windows计算机中。在启用显示隐藏文件和文件夹^{(Show hidden files and folder)}选项之前，您无法在系统的 C 驱动器中查看它。

按照以下步骤查看系统上的AppData文件夹：

1. 打开文件资源管理器。
2. 转到“View > Options”。这将打开文件夹选项^{(Folder Options)}窗口。
3. 单击查看^(View)选项卡。
4. 单击显示隐藏的文件、文件夹和驱动器^{(Show hidden files, folder, and drives)}选项。
5. 单击^(Click)应用^(Apply)按钮，然后单击确定以保存您所做的更改。

现在，转到以下路径：

C:\Users\<username>

<username>替换为您计算机上的用户名。在那里你会找到AppData文件夹。

当您打开AppData文件夹时，您会在其中找到三个子文件夹，即Local、LocalLow 和 Roaming。所有这三个子文件夹都是为不同的目的而创建的，该帖子中已对此进行了解释。

简而言之：

• ProgramData文件夹包含非用户特定的全局应用程序数据，并且可供计算机上的所有用户使用。任何全局数据都放在这里。
• AppData文件夹包含用户特定的首选项和配置文件配置，并进一步分为三个子文件夹：
  • 漫游^(Roaming)文件夹包含可以随用户配置文件从计算机移动到计算机的数据
  • 本地^(Local)文件夹包含无法随您的用户配置文件移动的数据。
  • LocalLow文件夹包括低级访问数据，例如。在受保护模式下运行时浏览器的临时文件。

Windows 10中的AppData文件夹是什么？

AppData 文件夹^{(AppData folder)}也称为Application Data 文件夹^{(Application Data folder)}。顾名思义，它是Windows计算机中存储程序使用或创建的数据的文件夹。AppData文件夹包含的数据不是原始安装文件的一部分。

它位于：

C:Users<用户名>AppData

您还可以在运行框中键入 % ^(Run)AppData %以访问AppData\Roaming文件夹。

安装程序时，运行该程序所需的所有文件都放在Program Files或Program Files x86文件夹中，而这些文件以外的数据则放在AppData文件夹中。这些数据包括：

• 程序缓存，
• 临时文件，
• 配置文件等

您可能想知道，为什么Windows使用单独的AppData文件夹来存储应用程序数据和文件，而不是将它们保存在Program Files或Program Files x86文件夹中的一个位置？好吧，将应用程序数据存储在单独的文件夹中有几个优点。

1. 易于管理用户数据^{(Easy to manage user data)}：如果您在系统上创建多个帐户，Windows将为每个用户创建一个单独的AppData文件夹。这使得管理特定应用程序的用户设置变得容易。例如，如果特定用户更改设置或自定义应用程序，则数据将存储在他自己的AppData目录中，而其他用户的配置文件对于同一程序不受影响。
2. 安全^(Security)性：单独的AppData文件夹也更安全，因为一个用户无法访问另一个用户的AppData文件夹。
3. 防止数据混乱^{(Prevent data from being messed up)}：因为每个用户都有一个单独的AppData文件夹，所以一个用户的设置和其他数据不会与其他用户的数据混淆。
4. 无法访问 Program Files 或 Program Files x86 文件夹^{(No access to the Program Files or the Program Files x86 folder)}：Program Files目录和Users目录具有不同的权限。前者是更高级别的目录，因此只有具有管理权限的人才能访问Program Files目录。如果应用程序数据存储在Program Files目录中，用户可能会遇到权限问题。

有些程序默认安装在AppData文件夹中，有些程序会要求您获得相同的权限。您可能已经安装了询问您是要为所有用户还是只为您安装它的程序。

如果您选择仅为我安装^{(Install only for me)} 选项，程序将被安装，应用程序安装到用户目录中。如果您选择For everyone^{(For everybody)}，则提示安装程序将程序安装到全局位置。

如果您无法找到或打开 AppData 文件夹，这篇文章将为您提供帮助。

What is the AppData folder in Windows 11/10? How to find it?

When we install a program, it may go to eithеr the Program Files folder or the Program Files x86 folder. Many of you might be aware of this fact. Every program has some customization features. When we run a program, we change its settings, customize its interface (if the feature is available), etc. This data is also stored on our computer’s hard disk, inside the AppData folder. In this article, we will discuss the AppData folder in detail.

Where is the AppData folder?

By default, the AppData folder is hidden in Windows computers. You cannot view it in the C drive of your system until you enable the Show hidden files and folder option.

Follow the steps to view the AppData folder on your system:

1. Open the File Explorer.
2. Go to “View > Options.” This will open the Folder Options window.
3. Click on the View tab.
4. Click the Show hidden files, folder, and drives option.
5. Click on the Apply button and then OK to save the changes that you made.

Now, go to the following path:

C:\Users\<username>

Replace <username> in the above path with your username on your computer. There you will find the AppData folder.

When you open the AppData folder, you will find three subfolders there, namely, Local, LocalLow, and Roaming. All these three subfolders are created for different purposes which have been explained in that post.

In short:

• ProgramData folder contains global application data that is not user-specific and is available to all users on the computer. Any global data is put in here.
• AppData folder contains user-specific preferences and profile configurations and is further divided into three subfolders:
  • Roaming folder contains data that can move with the user profile from a computer to a computer
  • Local folder contains data that cannot move with your user profile.
  • LocalLow folder includes low-level access data, eg. temporary files of your browser when running in a protected mode.

What is the AppData folder in Windows 10?

AppData folder is also called the Application Data folder. As the name implies, it is the folder in a Windows computer where the data that programs use or create is stored. The data that the AppData folder contains is not part of the original installation files.

It is located at:

C:\Users\<username>\AppData

You can also type %AppData% in Run box to access the AppData\Roaming folder.

When you install a program, all the files required to run it go in the Program Files or Program Files x86 folder, and the data other than these files go in the AppData folder. This data includes:

• Program cache,
• Temporary files,
• Configuration files, etc.

You might be wondering, why does Windows use a separate AppData folder to store the app data and files instead of keeping them in one place in the Program Files or Program Files x86 folder? Well, storing the app data in a separate folder has several advantages.

1. Easy to manage user data: If you create multiple accounts on your system, Windows will create a separate AppData folder for each user. This makes it easy to manage the user settings for a particular app. For example, if a particular user changes settings or customizes an app, the data is stored in his own AppData directory and the other users’ profiles remain unaffected for the same program.
2. Security: A separate AppData folder is also more secure because one user cannot access another user’s AppData folder.
3. Prevent data from being messed up: Because every user has a separate AppData folder, the settings and other data of one user are not messed up with the other user’s data.
4. No access to the Program Files or the Program Files x86 folder: The Program Files directory and the Users directory have different permissions. The former one is a higher level directory, hence, only the person with administrative rights can access the Program Files directory. If the app data were stored in the Program Files directory, users might have permission issues.

There are some programs that install in the AppData folder by default and some ask you permission for the same. You might have installed the programs that ask you whether you want to install it for all users or only for you.

If you select the Install only for me option, the program will be installed the application installs into a user directory. If you choose For everybody, it’s a hint for the installer to install the program into global locations.

This post will help you if you cannot find or open AppData folder.

We hope you find the article useful.
