在某些卷的文件资源管理器(File Explorer)中，您可能会看到一个名为FOUND.000的新文件夹，其中包含一个使用.CHK扩展名的文件。在这篇文章中，我们将解释这个文件夹是什么以及它包含的文件，并就如何从Windows 10中的文件夹中恢复文件提出建议。
可能导致问题的问题可能是；
- 磁盘错误：通常是因为在打开相关文件时突然关机。
- 在不使用安全移除设备的情况下拔出USB 闪存(USB Flash)或 SD 卡。
- 突然停电。
- 编辑文档时 Windows 10 操作系统突然崩溃。
- 恶意软件或病毒攻击。
什么是 FOUND.000 文件夹？如何恢复 .CHK 文件
通常，在扫描磁盘以查找错误时，Windows 内置的CHKDSK 工具会将您的数据转换为它认为有损坏的.chk 文件(.chk files)，然后将这些文件收集到Found.000 文件夹(Found.000 folder)中，而不是删除它们。在上图中，您可以看到FILE0000.CHK文件。
该文件夹默认是隐藏的——您需要显示隐藏的文件/文件夹才能在文件资源管理器中查看(File Explorer)FOUND.000文件夹。如果您尝试打开CHK文件，您会发现它们完全无法访问。虽然有时CHK文件因为损坏太严重而无法成功恢复，但其中许多可以再次使用，但您需要了解每个文件是什么类型的文件，并且需要应用正确的扩展名。
您可以使用第三方工具从Windows 10中的(Windows 10)FOUND.000文件夹中恢复文件。这些文件恢复软件(file recovery software)能够通过检查文件的标题并确定文件的类型以及其原始扩展名应该是什么来恢复CHK文件。(CHK)

4] TrIDNet有更好的机会识别计算机上可能无法被CHK(CHK)文件恢复工具之一拾取的模糊类型的文件。
5] FiletypeID的工作方式与TrIDNet相同，并使用相同的TrID库和定义来按文件类型而不是扩展名来识别文件，例如CHK文件。
6] CHK-back是一个易于使用的实用程序，支持大约 40 种文件格式，包括最常见的图像、视频、音频、可执行文件、文档和Office文件，以及Windows 地址簿(Windows Address Book)、Outlook Store、和Outlook Express邮件存储文件。
7] Fred(Frhed)(7] Frhed)是一个十六进制编辑器，可以让您读取文件中的文本，这可能有助于您准确了解CHK文件包含的内容。您可能无法在十六进制编辑器中读取任何数据，但这并不意味着该文件一文不值。但是，如果您看到的只是一堆 00，则意味着该文件完全是空的。
8] Windows 文件恢复工具(Windows File Recovery Tool)(8] Windows File Recovery Tool)可能会或可能不会恢复 FOUND.000 文件夹中的.CHK(FOUND.000)文件，但这是一个不错的小补充，您也可以尝试。

What is FOUND.000 folder? How to recover .CHK files from it?
In File Explorer on some volumes, you may see a new folder called FOUND.000 with a file in it using the .CHK extension. In this post, we will explain what this folder is and the file it contains and also make suggestions on how to recover files from the folder in Windows 10.
Problems that might cause the issue could be;
- Disk Errors: usually because of a sudden shutdown while the relevant files were opened.
- Unplugging the USB Flash or the SD card without using the safely remove device.
- Abrupt power outage.
- Sudden Windows 10 OS crash while editing a document.
- Malware or virus attack.
What is FOUND.000 folder? How to recover .CHK files
Usually, while scanning your disk for errors, Windows built-in CHKDSK tool will convert your data into .chk files which it thinks have corruptions, and then gather those files into a Found.000 folder instead of deleting them. In the above image, you can see the FILE0000.CHK file.
The folder is hidden by default – you need to show hidden files/folders to be able to view the FOUND.000 folder in File Explorer. And if you try to open the CHK files, you will find they are completely inaccessible. Although sometimes a CHK file cannot be recovered successfully because it has been too badly damaged, many of them can be used again, but you need to find out what type of file each one is and the correct extension needs to be applied.
You can recover files from FOUND.000 folder in Windows 10 by using third-party tools. These file recovery software are able to recover CHK files by checking the headers of the files and identifying what the type of file is and what its original extension should be.
Below are tools you can try:
1] UnCHK is a free CHK file recovery tool that is able to help you restore CHK files for around 25 different file formats to their original extension. You can read more about this and FileCHK here.
2] FileCHK is about as simple a tool as it gets, and has no options or interface at all. It simply scans your CHK files and renames them with the correct file extension if a recognized file type is detected.
3] ReclaiMeFileRecovery recovers data from hard drives (internal, external, and laptop), memory cards used in cameras, mobile phones, PDAs, MP3 players, USB drives (also called “thumb drives” or “pen drives”), RAID arrays, and multi-disk NAS devices.
4] TrIDNet has a better chance of identifying obscure types of files on your computer that might not get picked up by one of the CHK file recovery tools.
5] FiletypeID works along the same lines as TrIDNet and uses the same TrID library and definitions to identify files by their type and not the extension, such as CHK files.
6] CHK-back is an easy-to-use utility that has support for some 40 file formats, including the most common image, video, audio, executable, document, and Office files, as well as Windows Address Book, Outlook Store, and Outlook Express mail store files.
7] Frhed is a hex editor that can allow you to read text inside the file, which might help you learn exactly what the CHK file contains. You may not be able to read any data in the hex editor, but it doesn’t mean the file is worthless. However, if all you see are a bunch of 00’s, that means the file is completely empty.
8] Windows File Recovery Tool may or may not recover .CHK files in FOUND.000 folder but it’s a nice little addition here that you can try as well.
That’s it! Hope you find this post informative enough.
