Interrupted transfer process: The existence of interruptions such as a sudden system shutdown, Windows restarts, power failure, and others while transferring RAR files from a computer to an external storage device or vice versa may lead to checksum error RAR.
Insufficient disk space: If there is no more space for the Zip file to be extracted, you will receive the WinRAR checksum error.
Unreliable third-party compression tools: The checksum error WinRAR could also happen if you extract the contents of WinRAR with unreliable compression programs.
Virus/malware attacks: If there are virus/malware attacks in the RAR extraction process, the WinRAR checksum error might show up.
Bad sectors on the storage drive: Bad sectors also trigger the checksum error.

Solution 1: Use the Embedded Features in WinRAR

One of the WinRAR checksum error in the encrypted file fixes is to use the built-in features in WinRAR. Both the Keep broken files and Repair archive options of WinRAR can help you fix the WinRAR checksum error.

1. The Keep Broken Files Option

The Keep broken files option in WinRAR allows you to extract your corrupted media. Once you tick the option, WinRAR will ignore the corruption in the file and help you extract the content from the zip folder.

Note: When the RAR files to be extracted are severely corrupted, the Keep broken files option doesn’t work either.

Step 1: Right-click on the Zip or RAR compressed files and choose Extract Files from the context menu.

Step 2: Navigate to the Miscellaneous section and check the Keep broken files box.

Step 3: Choose an extraction location and then click OK to execute the changes. After a while, the file will be extracted to the selected location. However, it still shows the “checksum error”. You just need to ignore the error and open the file.

2. The Repair Archive Option

The Repair archive option in WinRAR can solve the checksum error and fix the corrupt file. Once it is clicked, it will automatically execute the operation. Besides, it doesn’t require Internet connection. Nevertheless, this method can only fix minor RAR file corruption.

Here’s how to use the Repair archive option.

Step 1: Right-click on the corrupted RAR or Zip file and tap the Open with WinRAR option.

Step 2: After the WinRAR opens, click on the Tools tab > Repair archive.

Step 3: Click the Browse button and then choose the destination for the repaired RAR or Zip files.

Step 4: Click OK to begin the process. After the operation ends, click Close to exit the program.

Solution 2: Download the RAR File Again

As mentioned earlier, interruptions during the file extraction process or incomplete download can also trigger the checksum error WinRAR. Given that fact, it is worth downloading the RAR file again.

To keep the process smooth, it is advised that you download the file to a different location. Moreover, you’d better ensure that you have a fast and stable Internet connection before downloading.

Solution 3: Reinstall WinRAR

Step 4: After the uninstallation, restart your computer. Then move to its official website to download and install it.

Solution 4: Disable Anti-Virus

Anti-Virus programs sometimes send false-positive warnings about malware-free software. Then they corrupt the files by deleting or adding them to their virus chest, which indicates that those files will be missing and you will receive the file corrupt error message.

To avoid that issue, you need to disable anti-virus programs on your computer. If you don’t have third-party anti-virus tools installed, you should disable Windows Defender with these steps.

Step 1: Open Windows Settings by holding Windows and I keys.

Step 2: In the main menu, click on Update & Security.

Step 3: Tap on Windows Security > Virus & threat protection.

Step 4: Click Windows Defender Antivirus Options and then set the status of Periodic Scanning to Off.
