"When I plugged my USB into PC, Windows asked to scan and repair the flash drive disk. Then I did it using the CHKDSK command line. But after that, some of my files, including JPEG pictures and videos turned into .chk files in the newly created Found.000 folder. Is there any way to convert .chk files to original format or recover files to their original location?"
When running Windows' built-in CHKDSK tool to scan for errors, it often converts potentially corrupted data to .chk files and stores them in a Found.000 folder, rather than deleting them. This is because CHKDSK is designed to preserve data that may be problematic, rather than erasing it.
To access the hidden folder, you need to enable the "hidden folder" option in the "View" tab of File Explorer. However, attempting to open the CHK files within will result in their inaccessibility, ultimately leading to a data loss disaster.
The FOUND.000 folder is created when a user runs the CHKDSK command, containing corrupted and fragmented data in the .chk extension. This folder and CHK files are typically created due to various reasons, including disk errors, file system corruption, or a failed system check.
On Windows, files with the .chk extension are often labeled as "recovered file fragments". If your data is already backed up, you can safely delete these files and free up space. However, if you've lost important data, you can try recovering it from your backup instead.
If you have no backup, but there are some important files that you've spotted in the Found.000 folder, you can check the following tutorials and learn how to recover files from the Found.000 folder in three ways.
Changing the CHK extension to a more recognizable file format, such as JPEG for pictures or MP4 for videos, is the simplest way to recover files from the Found.000 folder. This can be done by creating a copy of the .chk file and renaming the .chk files to their respective file formats. For example, if lost pictures are in JPEG format, rename the .chk files to .jpg files, or convert .chk files to .
To modify file extensions in bulk, you can use a combination of the `find` command and the `exec` command in Linux. Here's how:
Step 1. Create a text document on your computer.
Step 2. Double-click to open, type ren *.chk *.jpg, and save.
Step 3. Change the .txt suffix to .bat.
Step 4. Copy the .bat file to the Found.000 folder and double-click it to run, which will then convert the .chk files to .jpg files.
UnCHK is a free tool that recovers and converts CHK files from the Found.000 folder, allowing you to open and view the recovered files, although severely damaged files may not be recoverable.
If you've deleted the Found.000 folder but want to recover files from it, you can use Deep Data Recovery to help you recover the deleted folder or .chk files with minimal effort. After recovery, you can convert the chk files back to their original format and then open and recover them.
Qiling's data recovery and repair tool not only recovers damaged files but also repairs corrupted ones, supporting multiple file types including Word, Excel, PPT, PDF, photos, and videos.
Step 1. Run Deep Data Recovery. Select file types and click "Next" to start the recovery process.
Step 2. Click on the location where you lost the folder and click "OK" to scan. This will initiate a search for the missing folder on your computer.
Step 3. To search for the target folder, you can type the name of the folder in the search bar. Alternatively, you can use the Filter feature to narrow down the search results and find a specific type of file within the folder.
Step 4. After previewing the recovered folder, click "Recover" and select a new and secure location on your PC to save the recovered data.
You can recover files from the Found.000 folder by either converting the chk files to their original format using a tool like UnCHK or by using a file recovery tool like Qiling to recover the entire Found.000 folder, including any chk files. This can be helpful if the Found.000 folder is lost or deleted.
