如果您在将文件或文件夹从一个磁盘复制到另一个磁盘时收到错误复制文件或文件夹、请求的资源正在使用^{(Error Copying File or Folder, The requested resource is in use)}、消息，那么这篇文章将对您有所帮助。当您尝试复制的文件被其他应用程序使用或忙于其他进程时，会发生错误。Windows通常会锁定正在使用的文件或程序，因此没有其他进程对其进行修改。

错误 0x800700AA，复制时请求的资源正在使用中

复制文件^{(Copying File)}或文件夹^(Folder)时出错，请求的资源正在使用中

以下是解决此错误的几种方法，主要与阻止访问文件的程序有关。删除后，您将能够复制文件和文件夹。

1. 关闭预览窗格
2. 使用文件关闭程序
3. 在安全模式下扫描病毒
4. 恢复系统

确保^(Make)在按照上面列出的每种方法后检查问题是否已解决。只有这样，您才能理解是什么解决了问题。

在开始之前，请重新启动您的 PC 并重试。这已经知道工作很多次了。

1]在文件资源管理器^{(File Explorer)}中打开^(Turn)预览窗格^{(Preview Pane)}

此模式允许您查看目录中文件的预览。根据文件的数量，文件资源管理器^{(File Explorer)}可能需要一些时间来生成它，尤其是在您不经常打开它的情况下。在预览的生成过程中，文件处于锁定状态，如果您在该过程完成之前尝试复制它，可能会导致错误。由于文件资源管理器^{(File Explorer)}正在使用请求的资源，因此您可能无法复制它。

要解决它，请关闭预览窗格。切换到查看^(View)模式，然后单击预览窗格^{(Preview Pane)}将其禁用。您还可以使用ALT + P切换预览窗格。

2]使用文件关闭程序

如果任何程序正在使用这些文件中的任何一个，它将导致相同的错误。由于相同的问题，会出现类似问题，例如正在使用的源文件或目标文件，或者其他用户正在使用该程序。

我们建议像Process Explorer这样的应用程序关闭任何此类文件锁定。该应用程序会显示一个进程列表，如果您看到一个CPU使用率很高的程序，它将帮助您计算它。

3]在安全模式下扫描病毒

如果没有其他工作，则计算机上存在锁定文件和资源的流氓程序的可能性很小。建议您启动到安全模式，然后使用Windows Defender或任何其他安全软件扫描计算机。

由于Windows Defender有一个离线模式，它确保文件可以在没有互联网的情况下被扫描，并安全地删除。发布^(Post)这个；您可以毫无问题地复制文件。

4]系统还原

如果您启用了Windows 系统还原^{(Windows System Restore)}，那么明智的做法是切换到一切正常的日子。打开系统还原^{(System Restore)}，然后选择要还原的日期。

确保在进行系统还原时不要中断它。

Error 0x800700AA, The requested resource is in use when copying

If you reсeive Error Copying File or Folder, The requested resource is in use, message when copying files or folders from one disk to another, then this post will help you. The error occurs when the files you are trying to copy is used by some other application or busy with another process. Windows usually lock files or programs which are into use, so no other process modifies it.

Error 0x800700AA, The requested resource is in use when copying

Error Copying File or Folder, The requested resource is in use

Here are a few ways to resolve this error, and it’s mostly related to a program blocking access to the files. Once it is removed, you will be able to copy the files and folders.

1. Turn off Preview pane
2. Close Programs using the files
3. Scan for Virus in Safe Mode
4. Restore the System

Make sure to check if the issue was resolved after you follow each of the methods listed above. Only then will you be able to understand what fixed the problem.

Before you begin, restart your PC and try again. This has known to work many times.

1] Turn of Preview Pane in File Explorer

This mode allows you to see a preview of the files in a directory. Depending on the number of files, it may take some time for the File Explorer to generate it, especially if you open it less often. During the generation of the preview, the files are in the lock state, and if you try to copy it before the process is complete, it may result in an error. Since the requested resource is in use by the File Explorer, you may not be able to copy it.

To resolve it, switch off the preview pane. Switch to the View mode, and then click on Preview Pane to disable it. You can also use ALT + P to toggle the preview pane.

2] Close Programs using the files

If any program is using any of those files, it will result in the same error. Similar issues like source or destination files in use, or another user are using that program occur because of the same problem.

We recommend applications like Process Explorer to close any such file lock. The app reveals a list of processes, and if you see a program with high CPU usage, it will help you figure it.

3] Scan for Virus in Safe Mode

If nothing else works, there is a slight chance that there is a rogue program on the computer locking files and resources. It is recommended that you boot into the safe mode, and then scan the computer using Windows Defender or any other security software.

Since there is an offline mode for Windows Defender, it makes sure the file can be scanned without the internet, and safely removed. Post this; you can copy the files without any problem.

4] System Restore

If you have Windows System Restore enabled, then it is wise to switch to a day where everything is working. Open the System Restore, and then select a date to restore.

Make sure to not interrupt the System Restore while it is in progress.
