If you want to recover deleted, corrupted or shortcut files, you can definitely use the third-party data recovery software (get MiniTool Power Data Recovery from MiniTool Solution). However, you still have another choice: using the Command Prompt. It provides a free way for everyone to restore the deleted or lost files from USB drives, hard disks, and other storage devices.
CMD, the acronym of Command Prompt (also known as cmd.exe), is actually a command-line interpreter application you can find in any Windows operating systems. This tool provides you with a command-line interface to interact with the system. With it, you can do a lot of things on PC:
- Delete files and folders
- Manage disk and partition space
- Modify drive properties
- Solve disk problems
What’s more inspiring is that the CMD can also help you recover lost data. I’m going to demonstrate the exact steps to recover files using CMD in different cases. After that, I’ll also introduce another way to recover deleted files on Windows (how to retrieve deleted files on PC?).
Recover Files Using CMD: Exact Steps
Command Prompt is a snap-in tool in Windows systems, so you can open and use it easily for disk management, error fixing and data recovery. Your data can get lost due to a lot of reasons, such as accidental deletion, formatting and virus attack. Therefore, it’s necessary to teach you how to recover files using Command Prompt in some popular cases.
How to Recover Deleted Files Using Command Prompt
Generally, I advise you to check Recycle Bin when you delete files but find them still useful. Recycle Bin gives you a second chance for your mistaken deletion; it will store the accidentally deleted data for a certain period of time. Therefore, you can recover deleted files from Recycle Bin easily by dragging the files out directly or right clicking on needed files & choosing Restore.
There are some cases in which you have emptied the Recycle Bin or the file you have deleted is too large so it isn’t sent to the Recycle Bin. What should you do to recover the permanently deleted files? Definitely, Command Prompt data recovery should be your choice.
How do you use CMD to recover lost or deleted files? (I’m taking Windows 10 as an example.)
- Right click on the Start button at the lower left corner to open a menu (you can also press Windows + X key combinations).
- Choose Command Prompt (Admin) from the menu (the steps to run Command Prompt as an administrator in other operating systems are slightly different).
- Type chkdsk *: /f (* stands for the drive letter of the certain drive containing deleted files) into the Command Prompt window and press Enter.
- Wait for the command to complete.
- Type that drive letter again and press Enter.
- Type attrib -h -r -s /s /d *.* and press Enter.
- Wait for the command to complete.
Once the command has been finished, a new folder will be created on the drive to store all the recovered files, which will be in .chk format. You can finally change the format of those files and save them to the location you want. The CMD attrib command is usually used to recover permanently deleted files from CMD (you can also show hidden files using attrib command).
Please read this page if you are curious about where do deleted files go:
I find the question – where do deleted files go bothers a lot of people, so I decide to talk about it and then provide solutions for deleted file recovery.
What is CHK file?
In fact, CHK is the file extension for a temporary file format used in Windows. The CHK files are actually fragmented files which will be generated when:
- The writing process of files into a drive is stopped suddenly.
- The PC shuts down suddenly before you have a chance to save the opening files.
You can regard the CHK files as corrupted data.
What do these parameters in attrib command mean?
- -h: it gives the Hidden attribute to the files specified.
- -r: it refers to the read-only attribute (files can be read but cannot be changed).
- -s: it gives the System attribute to the files specified.
- /s: it tells the system to search the specified path (including subfolders).
- /d: it consists of process folders.
How to fix if attrib access denied?
Step one: make sure you are running Command Prompt as administrator.
Step two: check if there is any file in use.
The access will be denied if any files contained in the target drive are still used by other programs when you are running the command.
- Please close the programs and try again.
- If this fails, you need to start the computer in Safe Mode when you can’t track down the files.
Step three: check if you have enough permissions.
- Open Windows Explorer to locate the drive you want to run attrib command on.
- Right click on it and choose Properties.
- Shift to the Security tab.
- Find To change permissions, click Edit. and click on the Edit… button behind it.
- Click on the Add… button in the middle part of the window and type your username to allow account access. (You can also choose Everyone and click OK in the Security window to allow anyone to access the drive.)
- Find Group or user names area under Security tab.
- Select the Allow check for Full control.
- Click OK to confirm.
That’s all about how to recover CHK files using CMD.
