运行虚拟机^{(Virtual Machine)}时，很多时候您需要在主机计算机和 VM 之间传输文件。但许多用户报告说他们无法做到这一点。本文将指导您如何在虚拟机^{(Virtual Machine)}和主机之间传输文件。

VirtualBox是一款可让您在计算机上运行另一个操作系统的软件。您可以在计算机上运行多个操作系统，具体取决于RAM和处理器。运行虚拟机^{(Virtual Machine)}的系统称为主机。

在虚拟机^{(Virtual Machine)}和主机^{(Host Computer)}之间传输文件

^(VirtualBox)在主机和虚拟机之间共享文件时，VirtualBox有四个选项。让我们看看每一个的作用：

• 禁用^(Disable)：此选项禁用虚拟机和主机之间的文件传输。
• Host to Guest和Guest to Host：这两个选项启用单向文件共享。
• 双向^{(Bidirectional)}：此选项启用双向文件共享功能，即从 VM 到主机，反之亦然。

默认情况下，虚拟机设置为禁用。您必须将此设置更改为双向。以下步骤将帮助您做到这一点。

1. 启动VirtualBox并选择要启用双向文件传输选项的操作系统。
2. 单击“设置^(Settings)”按钮。将打开一个新窗口。
3. 选择左侧的“常规^(General)”。
4. 在“高级”选项卡下，从^(Advanced)共享剪贴板^{(Shared Clipboard)}和拖放^(Drag)选项的下拉菜单中选择“双向^{(Bidirectional)}”^(Drop)。
5. 单击确定以保存设置。

现在，启动虚拟机^{(Virtual Machine)}并检查复制和粘贴或拖放功能是否正常工作。如果您无法在虚拟机^{(Virtual Machine)}和主机之间传输文件，则必须安装VirtualBox Guest Additions。

请按照下列步骤操作：

1. 在虚拟机中，转到“Devices > Insert Guest Additions CD image”。
2. 在 VM 中打开文件资源管理器^{(File Explorer)}并转到此 PC。
3. 打开“ CD 驱动器 (D)：VirtualBox 来宾添加^{(CD Drive (D): VirtualBox Guest Additions)}。”
4. 您将找到三个安装文件。首先^(First)，尝试安装“ VBoxWindowsAdditions-amd64 ”。如果此Guest Addition 未安装在您的计算机上，请尝试安装另一个。Guest Additions的安装取决于主机的体系结构。
5. 安装完成后，重新启动虚拟机^{(Virtual Machine)}并检查您是否能够双向传输文件。

就我而言，复制和粘贴仅适用于文本，不适用于文件传输。但是，我能够通过拖放方法传输文件。

希望这篇文章对你有所帮助。

How to transfer files between Virtual Machine and Host Computer

When you run a Virtυal Machine, many times yоu require to trаnsfer files betwеen your host computer and the VM. Bυt many users reported that they are unable to do this. This article guides you on how to transfer files between a Virtual Machine and a host computer.

VirtualBox is a software that lets you run another operating system on your computer. You can run multiple operating systems on your computer depending on RAM and processor. The system on which the Virtual Machine runs is called the host computer.

Transfer files between Virtual Machine and Host Computer

VirtualBox has four options when it comes to sharing the files between the host computer and the VM. Let’s see the function of each one:

• Disable: This option disables the file transfer between VM and host machine.
• Host to Guest and Guest to Host: These two options enable one-way file sharing.
• Bidirectional: This option enables the two-way file sharing feature, i.e., from VM to host machine and vice versa.

By default, the Virtual Machine is set to disable. You have to change this setting to bidirectional. The following steps will help you do this.

1. Launch VirtualBox and select the operating system for which you want to enable the bidirectional file transfer option.
2. Click on the ‘Settings‘ button. A new window will open.
3. Select ‘General‘ on the left side.
4. Under the ‘Advanced‘ tab, select ‘Bidirectional‘ from the drop-down menu in Shared Clipboard and Drag n Drop options.
5. Click OK to save the settings.

Now, launch the Virtual Machine and check whether the copy and paste or drag n drop feature is working or not. If you are not able to transfer the files between the Virtual Machine and the host computer, you have to install the VirtualBox Guest Additions.

Follow the below-listed steps:

1. In the Virtual Machine, go to ‘Devices > Insert Guest Additions CD image.’
2. Open the File Explorer in VM and go to This PC.
3. Open ‘CD Drive (D): VirtualBox Guest Additions.’
4. You will find three installation files. First, try to install ‘VBoxWindowsAdditions-amd64.’ If this Guest Addition does not install on your computer, try installing another one. The installation of the Guest Additions depends on the architecture of the host computer.
5. After the installation gets completed, reboot the Virtual Machine and check whether you are able to transfer the files bidirectionally or not.

In my case, the copy and paste was working only for the text and not for file transfer. But, I was able to transfer the files by the drag n drop method.

Hope this article helped you.
