文件资源管理器中的缩略图^{(Thumbnails in File Explorer)}使您即使不打开文件也能更轻松地识别文件。有时，由于各种原因，您可能会发现文件缩略图未显示在 Windows 10 PC 上。

有几个项目可能会破坏您的文件缩略图。设置^(Settings)中的选项、缩略图缓存错误和系统文件损坏是Windows 10 中未显示缩略图的部分原因。^{(your thumbnails)}

幸运的是，有几种方法可以解决这个问题。

使用支持的视图类型^{(Use the Supported View Type)}

文件资源管理器^{(File Explorer)}提供多种视图类型，因此您可以以您喜欢的样式查看文件。但是，其中一些视图选项不提供缩略图。 

以下是没有缩略图的图片文件夹的外观。

如果您使用其中一种不受支持的视图类型，则可能是您看不到文件缩略图的原因。

更改视图类型，这应该可以解决您的问题：

1. 打开不显示文件缩略图的文件夹。
2. 在文件夹中的任何空白处，右键单击并选择查看^(View)。

1. 从View菜单中，选择不是List或Details的视图。这两种视图类型不显示文件缩略图。

1. 您现在应该看到您的文件缩略图。

在文件资源管理器中启用缩略图^{(Enable Thumbnails in File Explorer)}

在设置^(Settings)应用程序和文件资源管理器的文件夹选项^{(Folder Options)}窗口中，有一个选项隐藏和显示文件缩略图。如果您或某人修改了此选项，这可能是您看不到文件缩略图^{(don’t see your file thumbnails)}的原因。

要解决这种情况下的问题，请在Settings或Folder Options中修改该选项。

从设置^{(From Settings)}

   start explorer.exe

1. 您现在可以关闭命令提示符^{(Command Prompt)}窗口。

打开文件资源管理器^{(File Explorer)}窗口，您应该会看到文件缩略图。

更改文件类型的默认应用程序^{(Change the Default App for a File Type)}

如果您没有看到仅特定文件类型^{(certain file type)}的缩略图，则值得更改该文件的默认文件查看器以查看是否可以解决您的问题：

1. 在文件资源管理器^{(File Explorer)}中，找到您看不到缩略图的文件类型。
2. 右键单击该文件类型并选择Open with > Choose another app。

1. 在打开的框中，为所选文件类型选择适当的文件查看器。

您在 PC 上安装的应用程序也可能导致您的缩略图不显示。如果您在安装应用程序后立即遇到缩略图问题，则该应用程序可能是罪魁祸首。

在这种情况下，请删除该应用程序^{(remove that app)}并查看您的问题是否得到解决：

1. 同时按Windows + I键打开设置。^(Settings)
2. 在设置中选择应用程序。^(Apps)

1. 在打开的应用和功能^{(Apps & features)}页面上，向下滚动列表并找到您的应用。
2. 在列表中选择您的应用，然后选择卸载^(Uninstall)。

1. 从出现的提示中，选择Uninstall。

1. Windows 10 将从您的 PC 中删除选定的应用程序。

修复损坏的文件^{(Fix Corrupt Files)}

Thumbnails Not Showing Up in Windows 10? 9 Easy Fixes

Thumbnails in File Explorer make it easier for you to identify files even without opening the files. Sometimes, you may find that the file thumbnails are not showing up on your Windows 10 PC due to various reasons.

Several items can break your file thumbnails. An option in Settings, a faulty thumbnails cache, and corrupt system files are some of the reasons your thumbnails aren’t showing up in Windows 10.

Luckily, there are a few ways to get around this issue.

Use the Supported View Type

File Explorer offers multiple view types so you can view your files in your preferred style. But, some of these view options don’t offer thumbnails. 

The following is how a picture folder looks without thumbnails.

If you’re using one of these non-supported view types, that may be the reason you don’t see your file thumbnails.

Change the view type and that should resolve your issue:

1. Open the folder that displays no thumbnails for your files.
2. On any blank space in the folder, right-click and select View.

1. From the View menu, choose a view that’s not List or Details. These two view types don’t display file thumbnails.

1. You should now see your file thumbnails.

Enable Thumbnails in File Explorer

In the Settings app and File Explorer’s Folder Options window, an option hides and displays file thumbnails. If you or someone has modified this option, that’s a possible reason you don’t see your file thumbnails.

To fix the issue in this case, modify the option either in Settings or in Folder Options.

From Settings

1. Press the Windows + I keys at the same time to open Settings.
2. Select System in Settings.

1. Scroll down the sidebar on the left and choose About.

1. In the Related settings menu to the far right of your screen, select Advanced system settings.

1. From under the Performance section, choose Settings.

1. Various options with a checkbox will appear on your screen. From this options list, find and enable the Show thumbnails instead of icons option.

1. Select Apply followed by OK at the bottom of the window.

From Folder Options

1. Open a File Explorer window.
2. At the top of the window, select View and then select Options.

1. In the Folder Options window that opens, select the View tab.

1. Under the Advanced settings section, disable the Always show icons, never thumbnails option.

1. Select Apply followed by OK at the bottom of the window.

Rebuild the Thumbnail Cache

Your Windows 10 PC uses the thumbnails cache to display file thumbnails in File Explorer quickly. If this cache has an issue, your thumbnails won’t appear properly.

Luckily, you can delete this cache without affecting any of your files, and Windows 10 will then automatically rebuild this cache for you. There are two ways to rebuild the thumbnail cache.

Using a Graphical Method

1. Press Windows + E to launch a File Explorer window.
2. In File Explorer, from the sidebar on the left, select This PC.
3. Find the drive where you’ve installed Windows (usually the C drive), right-click this drive, and select Properties.

1. In the Properties window, choose Disk Cleanup.

1. A Disk Cleanup window will open. Here, in the Files to delete section, enable the Thumbnails option. Deselect all other options. Then, select OK at the bottom.

1. A prompt will appear asking to confirm your choice. Select Delete Files in this prompt.

Using Command Line

1. Open the Start menu, search for Command Prompt, and select Run as administrator on the right.

1. Select Yes in the User Account Control prompt.
2. In the Command Prompt window that opens, type the following command and press Enter. This closes the File Explorer utility.
   
   taskkill /f /im explorer.exe

1. Then, run the following command:
   
   del /f /s /q /a %LocalAppData%\Microsoft\Windows\Explorer\thumbcache_*.db

1. Relaunch File Explorer by running the following command:
   
   start explorer.exe

1. You may now close the Command Prompt window.

Open a File Explorer window, and you should see your file thumbnails.

Change the Default App for a File Type

If you don’t see thumbnails only for a certain file type, it’s worth changing the default file viewer for that file to see if that fixes your issue:

1. In File Explorer, find the file type for which you don’t see the thumbnails.
2. Right-click that file type and select Open with > Choose another app.

1. In the box that opens, select an appropriate file viewer for the chosen file type.
2. At the bottom of the box, enable the Always use this app to open .jpg files (where jpg is the file type you’ve selected).

1. Select OK at the bottom of the window.

Scan PC for Viruses and Malware

A malicious item like a virus can cause your PC to malfunction. In some cases, this causes various File Explorer elements to not show up, including thumbnails. If this is the case with your computer, you should run a virus checker and get rid of any viruses from your machine.

The good thing about Windows 10 is that it comes built with a virus scanner. This scanner is called Microsoft Defender Antivirus, and you can use this free tool to find and remove viruses from your system.

1. Open the Start menu, search for Windows Security, and select that in the search results.

1. Select Virus & threat protection on the screen that follows.

1. Select Scan options.

1. Choose the Full scan option and then select the Scan now button.

1. Wait for Microsoft Defender Antivirus to scan your PC for any viruses and malware.

Uninstall the Problematic App

An app you’ve installed on your PC can also cause your thumbnails not to show up. If you’re experiencing the thumbnails issue right after installing an app, that app might be the culprit.

In this case, remove that app and see if your problem gets resolved:

1. Open Settings by pressing Windows + I keys at the same time.
2. Select Apps in Settings.

1. On the Apps & features page that opens, scroll down the list and find your app.
2. Select your app in the list and then select Uninstall.

1. From the prompt that appears, choose Uninstall.

1. Windows 10 will remove the selected app from your PC.

Fix Corrupt Files

Often, corrupt files cause various issues on Windows PCs, including causing File Explorer not to display any thumbnails. You don’t have to worry about anything if this is the case, as Windows 10 includes a command to find and fix corrupt files.

1. Right-click the Start menu icon and choose Command Prompt (Admin) from the menu.

1. Select Yes in the User Account Control prompt.
2. On the Command Prompt window, type the following command and press Enter:
   
   sfc /scannow

1. Wait for Windows to find and fix corrupt files on your computer.

Reset File Explorer Options

It’s worth resetting the File Explorer options to see if your file thumbnails come back. Doing so should fix any improperly configured options in the File Explorer settings.

1. In a File Explorer window, select View at the top and then choose Options.
2. Select the View tab in the Folder Options window.
3. At the bottom, choose the Restore Defaults button.

1. Select Apply followed by OK at the bottom.

Free Up Space on Your PC

To create and save file thumbnails, File Explorer needs disk space on your computer. If your PC is running out of space, that may be the reason you don’t see your thumbnails.

To fix this, check out our dedicated guide to free up disk space in Windows 10. The guide offers tips to get rid of unwanted files and reclaim your precious storage.

And that should fix the issue with file thumbnails on your Windows 10 PC. If it did, don’t forget to let us know what method worked for you in the comments below.
