如果您在将文件复制到外部存储设备或从外部存储设备复制文件时遇到错误0x800703EE ，那么这些帖子将对您有所帮助。^(0x800703EE)此错误可能会或可能不会伴随此消息 -文件的卷已从外部更改，因此打开的文件不再有效^{(The volume for a file has been externally altered so that the opened file is no longer valid)}。这可以防止您复制文件。

复制到外部存储时出现 0x800703EE 错误

此错误的原因可能是其中任何一个：

1. 与第 3 方防病毒软件的冲突。
2. 属于备份程序的服务可能会阻止该程序。
3. USB驱动程序可能已损坏或过时。
4. 可以禁用Windows 备份^{(Windows Backup)}和卷影复制^{(Shadow Copy)}
5. 某些系统文件可能已损坏
6. 外部设备的驱动程序已损坏。

在开始之前，也许您可​​以将文件移动到本地驱动器上的另一个位置，移除USB设备，重新插入，然后尝试将文件从本地驱动器移动到USB设备。如果这没有帮助，请尝试以下解决方案来解决问题：

1. 重新安装USB控制器驱动程序
2. 检查卷影复制^{(Shadow Copy)}和Windows 备份^{(Windows Backup)}服务
3. 禁用第三方杀毒产品的实时保护
4. 执行 SFC 扫描
5. 删除过滤器驱动程序。

1]重新安装USB控制器驱动程序

如果USB 控制器驱动程序^{(USB controller drivers)}已过时或损坏，则可能会导致此问题。在这种情况下，您可以按如下方式更新它们：

Press Win+R打开“运行”^(Run)窗口并键入命令devmgmt.msc。按 Enter^{(Hit Enter)}打开设备管理器^{(Device Manager)}。

滚动到通用串行总线控制器^{(Universal Serial Bus Controllers)}并展开列表。

右键单击并分别为每个驱动程序选择卸载设备。^{(Uninstall device)}

然后重启系统，连接网络，驱动会自行重新安装。

您也可以从制造商的网站下载外部设备的驱动程序^{(download the drivers)}并进行安装。

2]检查^(Check)卷影复制^{(Shadow Copy)}和Windows备份^{(Windows Backup)} 服务^(Services)

讨论中的问题的原因之一是卷影复制^{(Shadow Copy)}和Windows 备份^{(Windows Backup)}服务可能被禁用或未启动。

Press Win + R打开“运行”^(Run)窗口并键入命令services.msc。按 Enter打开服务管理器^{(open the Service Manager)}。

搜索卷影复制^{(Volume Shadow Copy)}服务并右键单击它。选择属性^(Properties)。确保启动类型^{(Startup type)}为手动^(Manual)并且服务^(Service)已启动^(Start)。如果不是，请更改它并单击“开始^(Start)”按钮。单击^(Click)应用^(Apply)，然后单击确定以保存设置。

对Window Backup 服务^{(Window Backup service)}重复相同的过程，然后查看是否可以立即复制。

3]禁用^(Disable)第三方杀毒产品的实时保护

众所周知，许多第三方防病毒产品会导致与正版文件发生冲突。他们可能会过度保护系统。在这种情况下，解决问题的方法是暂时禁用这些第三方防病毒产品的实时保护，看看是否有帮助。

4]执行SFC扫描

如果系统中缺少任何系统文件，则可能会导致外部存储出现 0x800703EE 错误。要解决此问题，请执行SFC 扫描。它检查丢失或损坏的系统文件并替换它们。

5]删除过滤器驱动程序

仅当您看到文件的卷已从外部更改，因此打开的文件不再是有效^{(The volume for a file has been externally altered so that the opened file is no longer valid)}的错误消息时，此建议才适用，错误代码为 0x800703EE。

首先创建系统还原点或备份注册表^{(back up the Registry)}，然后删除过滤器^(Filter) 驱动程序^(Drivers)。为此，请运行^(Run) regedit并导航到以下键：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

选择此键{4D36E965-E325-11CE-BFC1-08002BE10318}，然后在右窗格中检查是否存在 Upperfilters^{(Upperfilters)}和Lowerfilters值。如果是，则右键单击这些值并选择删除^(Delete)以删除它们，然后重新启动计算机。如果没有，则退出注册表编辑器^{(Registry Editor)}。

祝一切顺利。^{(All the best.)}

0x800703EE error when copying files to external storage on Windows

If you are facing error 0x800703EE while copying files to and from external storage devices, then these posts will help you. This error may or may not be accompanied by this message – The volume for a file has been externally altered so that the opened file is no longer valid. This prevents you from copying the files.

0x800703EE error when copying to external storage

The causes of this error could be any of them:

1. A conflict with a 3rd party antivirus.
2. A service belonging to a backup program could be blocking the program.
3. USB drivers could be corrupt or outdated.
4. The Windows Backup and Volume Shadow Copy could be disabled
5. Some system files could be corrupt
6. The drivers of the external device are corrupt.

Before you begin, maybe you could move the files to another location on your local drive, remove the USB device, insert it again, and then try to move the file from your local drive to the USB device. If this does not help,  try the following solutions to resolve the problem:

1. Reinstall the USB controller drivers
2. Check the Volume Shadow Copy and Windows Backup services
3. Disable real-time protection of third-party anti-virus products
4. Perform an SFC scan
5. Delete Filter Drivers.

1] Reinstall USB controller drivers

The issue could be caused if the USB controller drivers are outdated or corrupt. In this case, you can update them as follows:

Press Win+R to open the Run window and type the command devmgmt.msc. Hit Enter to open the Device Manager.

Scroll to Universal Serial Bus Controllers and expand the list.

Right-click and select Uninstall device for each driver individually.

Then restart the system, connect to the internet, and the drivers will reinstall by themselves.

You can also download the drivers for the external device from the manufacturer’s website and install it.

2] Check the Volume Shadow Copy & Windows Backup Services

One of the reasons for the issue in discussion is that the Volume Shadow Copy and Windows Backup services might be disabled or not started.

Press Win + R to open the Run window and type the command services.msc. Press Enter to open the Service Manager.

Search for the Volume Shadow Copy service and right-click on it. Select Properties. Make sure that the Startup type to Manual and that the Service is Started. If it isn’t, then change it and click the Start button. Click on Apply and then on OK to save the settings.

Repeat the same process for the Window Backup service and then see if you can copy now.

3] Disable real-time protection of third-party anti-virus products

Many third-party anti-virus products are known to cause conflicts with genuine files. They could become overprotective of the system. The resolution to the problem, in this case, would be to temporarily disable real-time protection with these third-party anti-virus products and see if that helps.

4] Perform SFC scan

In case any system files are missing from the system, it could cause the 0x800703EE error with external storage. To resolve the problem, perform an SFC scan. It checks for missing or corrupted system files and replaces them.

5] Delete Filter Drivers

This suggestion is applicable only IF you see The volume for a file has been externally altered so that the opened file is no longer valid error message with the error code 0x800703EE.

Create a system restore point or back up the Registry first and then delete Filter Drivers.  To do so, Run regedit and navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Select this key {4D36E965-E325-11CE-BFC1-08002BE10318} and then in the right pane, check if Upperfilters and Lowerfilters values are present. If they are, then right-click on the values and select Delete to remove them, and restart the computer. If not, then exit the Registry Editor.

All the best.
