如果当您尝试访问 Windows 10 计算机、外部硬盘驱动器或其他 USB 设备上的某些文件或文件夹时，遇到错误消息系统无法访问文件并^{(The file cannot be accessed by the system)}伴随错误代码0x80070780，那么这篇文章旨在帮你。

错误 0x80070780，系统无法访问该文件

如果您遇到此问题，您可以尝试以下我们推荐的解决方案（不分先后顺序），看看是否有助于解决问题。

1. 运行 Windows 文件^{(Run Windows File)}和文件夹疑难解答^{(Folder Troubleshooter)}
2. 运行 CHKDSK
3. ^(Carry)在安全模式下^{(Safe Mode)}进行文件操作
4. 使用 Robocopy
5. 重新安装磁盘驱动程序
6. 备份数据和格式化驱动器

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

在尝试任何这些解决方案之前，请确保您以 Windows 10 设备上的管理员身份登录并尝试文件夹/文件操作。如果它不起作用，您现在可以继续如下。

1]运行Windows文件^{(Run Windows File)}和文件夹疑难解答^{(Folder Troubleshooter)}

您可以运行 Windows 文件和文件夹疑难解答，看看问题是否会得到解决。该向导将自动诊断和修复文件和文件夹的问题——这些问题可能包括无法从回收站^{(Recycle Bin)}中删除文件或文件夹，或者尝试复制、移动、重命名或删除文件时出现问题。

2]运行CHKDSK

由于系统错误或硬盘驱动器上有坏扇区，您可能会遇到此问题。在这种情况下，您可以在内部和外部驱动器上运行 CHKDSK ^{(run CHKDSK )}，看看问题是否会得到解决。如果需要，您可以使用第三方软件运行 CHKDSK^{(run CHKDSK with third-party software)}。

3]在安全模式下^{(Safe Mode)}进行^(Carry)文件操作

以安全模式启动 Windows 10^{(Boot Windows 10 in Safe Mode)}或执行干净启动^{(perform a Clean Boot)}，然后尝试执行您想要的复制、粘贴、编辑等文件操作。这可能会有所帮助。

4]使用Robocopy

如果您在尝试使用Windows 10^{(Windows 10)}中默认的本机文件传输功能将文件从一个位置复制到另一个位置时遇到此错误，您可以尝试内置的 Robocopy 命令行工具。

5]重新安装磁盘驱动程序

设备^(Device)驱动程序问题也可能是罪魁祸首，例如Windows 10未检测到USB，这也可能导致文件无法访问。要排除驱动问题的可能性，您需要重新安装设备驱动程序。就是这样：

• 如果出现问题，请将USB驱动器连接到计算机。^(USB)
• 按Windows key + X打开高级用户菜单。
• 按键盘上的M键打开设备管理器^{(Device Manager)}。
• 进入设备管理器^{(Device Manager)}后，向下滚动已安装设备列表并展开磁盘驱动器 ^{(Disk drives )}部分。
• 接下来，右键单击您的USB驱动器并选择Uninstall device。
• 在提示上单击“确定^(OK)”以确认删除。

卸载过程完成后，断开USB驱动器并重新启动计算机。启动时，将USB驱动器重新连接到 PC，Windows 10 将自动重新安装驱动程序。尝试您之前执行的文件/文件夹操作，看看操作是否在没有问题的情况下完成。否则^(Otherwise)，请尝试下一个解决方案。

6]格式化驱动器

格式化驱动器有助于解决文件系统错误，并可能有助于修复一些可能导致焦点错误的磁盘错误。

格式化将擦除驱动器上现有的所有文件，因此在格式化内部驱动器^{(formatting the internal drive)}或格式化外部驱动器^{(formatting the external drive)}之前， 将文件备份^{( your files)}到另一个外部设备或云存储服务^{(cloud storage service)}，视情况而定。

希望这可以帮助！

Error 0x80070780, The file cannot be accessed by the system

If when you try to access some files or folders on your Windows 10 comрuter, external hard drive, or other USB devices but encounter the error message The file cannot be accessed by the system with the accompanying error code 0x80070780, then this post is intended to help you.

Error 0x80070780, The file cannot be accessed by the system

If you’re faced with this issue, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

1. Run Windows File and Folder Troubleshooter
2. Run CHKDSK
3. Carry out the file operation in Safe Mode
4. Use Robocopy
5. Reinstall the disk driver
6. Backup data and Format drive

Let’s take a look at the description of the process involved concerning each of the listed solutions.

Before you try any of these solutions make sure you’re logged on as administrator on your Windows 10 device and try the folder/file operation. If it doesn’t work, you can now continue as follows.

1] Run Windows File and Folder Troubleshooter

You can run Windows File and Folder Troubleshooter and see if the issue will be resolved. The wizard will automatically diagnose and repair problems with files and folders – these problems might include the inability to delete files or folders from the Recycle Bin, or troubles with trying to copy, move, rename, or delete a file.

2] Run CHKDSK

You may be experiencing this issue due to system error or having bad sectors on the hard drive. In this case, you can run CHKDSK  on both the internal and external drive and see if the issue will be resolved. You can run CHKDSK with third-party software if you want.

3] Carry out the file operation in Safe Mode

Boot Windows 10 in Safe Mode or perform a Clean Boot and then try to carry out the copy, paste, edit, etc, file operation that you wanted. It is likely to help.

4] Use Robocopy

If you are encountering this error when you try to copy files from one location to another using the default native file transfer function in Windows 10, you can try the built-in Robocopy command-line tool.

5] Reinstall the disk driver

Device driver issues is also a likely culprit, like USB not detected by Windows 10, which can also make the files inaccessible. To rule out the possibility of driver issues, you need to reinstall device driver. Here’s how:

• Connect your USB drive to your computer if that’s where the problem occurs.
• Press Windows key + X to open the Power User Menu.
• Press M key on the keyboard to open Device Manager.
• Once you’re inside Device Manager, scroll down through the list of installed devices and expand the Disk drives section.
• Next, right-click on your USB drive and choose Uninstall device.
• Click OK on the prompt to confirm the removal.

When the uninstallation process completes, disconnect the USB drive and restart your computer. On boot, reconnect the USB drive to the PC, Windows 10 will automatically reinstall the driver. Try the file/folder action you performed earlier and see if the operation completes without the issue at hand. Otherwise, try the next solution.

6] Format the drive

Formatting a drive can help solve file system errors and may help fix some disk errors that may result in the error in focus.

Formatting will erase all the files existing on the drive, so back up your files to another external device or a cloud storage service, before formatting the internal drive or formatting the external drive, as the case may be.

Hope this helps!
