Fix: 7-zip “There Are Some Data After the End of the Payload Data”

Fix 7-zip There Are Some Data After the End of the Payload Data

Have you ever encountered the “There are some data after the end of the payload data” warning message when you try to extract an archive?

If so, you’re not alone. 

This issue is common—but it isn’t always easy to solve.

In this article, we’ll explore what this warning means and provide two solutions for resolving it. 

Let’s get into some troubleshooting, shall we?

Key Takeaways

  • The warning message ‘There are some data after the end of the payload data’ is common in 7-Zip.
  • It is a reminder to double-check the archive and avoid incomplete extraction and file corruption.
  • The warning can be caused by a 7-Zip bug, outdated software, or malicious programs.
  • 7-Zip Builds 16.02 and older builds have a bug related to RAR encryption, but it does not affect the extraction process.


You’re likely to get the ‘There are some data after the end of the payload data’ warning message if you have a 7-Zip bug.

This unconventional error is a type of warning message that doesn’t really interfere with the extraction process. It’s triggered when you use the 7-Zip application, but it won’t interrupt what you’re doing.

The goal of this message is to alert users that there could be more data in an archive than what they think and it’s best to double check before extracting anything.

Pay attention to this warning, as it may save time and effort by avoiding incomplete extraction processes and unnecessary file corruption.

Be sure to take appropriate action if you encounter this type of error so that your files remain intact and uncompromised.

To avoid such warnings in future extractions, be sure to source reliable archives from trusted sources and always scan for viruses or malware before attempting any file extraction activities.

What Does The Message ‘There are some data after the end of the payload data’ Mean?





It means extra info was found after the archive had been extracted.

This error occurs when something outdated is used to create an archive, as it writes additional data after the end of the file.

There are several potential causes for this issue – some more serious than others. For example, a malicious program could be lurking in the extra data, or it could simply be corrupted files from old software.

To identify which one is causing your issue, you can try using a different archiving tool and check if the same error persists.

You should also check any anti-virus software you have installed on your computer in case anything malicious has snuck its way into your system.

It’s also best to ensure that all of your programs are up-to-date so that they don’t produce outdated archives with this problem. With these steps completed, you should be able to resolve ‘there are some data after the end of the payload data’ errors!

What causes the “There are some data after the end of the payload data” warning message?

You may be seeing the “There are some data after the end of the payload data” warning message due to a 7-Zip bug.

This bug occurs when 7-Zip fails to detect the archive type. As a result, the 7-Zip utility reports an archive error, triggering the alert. To prevent this issue, ensure that your archives are correctly identified by 7-Zip.

1. A 7-Zip bug

7-Zip has a known bug that results in this warning message. The cause of this issue is unknown, but it’s speculated to be related to using RAR encryption on certain types of data.




Fortunately, the developers have addressed this bug in more recent builds so you don’t have to worry about it anymore.

If you’re still using an older version of 7-Zip, make sure to upgrade it if you want to avoid this issue,  check to see if you still have the error.

Sometimes, a bug or glitch in 7-Zip or the software used to create the archive can cause this error.

This is especially true if you’re using an older version of the 7-Zip software.

Here are some ways this could happen:

  • The archive was created with other software that wrote additional data at the end.
  • The error appears as a glitch, even if both the archive and its contents are perfectly fine.
  • It’s particularly common if an outdated version of 7-Zip is being used.
  • Sometimes, it appears simply due to a technical issue without any corrupt files present.
  • In rare cases, there might be some data after the payload data which causes this error message.

Regardless, it’s important to note that even when this error shows up, your files may still be safe and sound!

2. Could be an archive error

Recently, 7-Zip’s newest builds have been reporting errors with certain file types, such as TAR archives.

This is because bad sectors from TAR files were not previously reported by 7-Zip, but the latest builds now alert users to their presence.

The error is expressed as ‘there are some data after the end of the payload data.’ In other words, this indicates that there are issues with the archive that can’t be fixed.

To avoid this problem in the future, it’s best to use other compression utilities for extracting TAR archives or repair them before attempting an extraction using 7-Zip.3. 

3. 7-Zip utility is failing to detect archive type

The 7-Zip utility may be unable to detect the archive type of a file.

This can manifest as a warning message or an error when attempting to open the file.

It’s important to understand why this can occur and how it can be addressed:

  1. The file may have been corrupted, either by mistake or maliciously.
  2. It may not have the right extension for the archive type.
  3. There could be some data after the end of the payload data.
  4. Or, there could be an issue with 7-Zip itself that is causing it to fail in recognizing the type of archive.

To diagnose and fix this problem, users are recommended to check their files against known good versions, update their software if necessary, and confirm they are using the correct version of 7-Zip for their particular file format.

4. Has The Archive Been Tampered With?

If you suspect that the archive has been tampered with, check its MD5 hash to verify its authenticity.

Malicious actors can distribute fake versions of an archive in order to infect computers and this is often done through the extraction process. Fortunately, 7-Zip itself is safe but it can still be used for malicious purposes if not used correctly.

To ensure an archive hasn’t been tampered with, use a tool like WinMD5Free to generate an MD5 hash and compare it to the one listed on the website where you downloaded the file from. If they don’t match then it’s likely that someone has altered the contents of your archive.

It’s important to stay vigilant when downloading files as there are numerous ways malicious actors can take advantage of unsuspecting users.

5. The Archive May Contain A Virus

It’s possible that an archive contains a virus, although this is very rare. To be safe when downloading files from the internet, you should use VirusTotal or another similar website to scan the file with multiple antiviruses before opening it.

Occasionally, false positives can occur where an antivirus incorrectly reports a virus in a clean file; however, since many scans are done at once, the chances of this happening are significantly reduced.

If you suspect that your archive may have been tampered with or contains a virus, it’s important to take these extra precautions before accessing its contents.

6. 7-Zip Is Unable To Detect The Archive Type (Specific Files)

Sometimes it can be difficult for 7-Zip to detect the type of archive you’re trying to extract, so if that’s happening to you don’t worry.

In these cases, adding the file extension or changing it entirely may help.

If the extraction succeeds and the files appear to be fine, a glitch or bug is likely at fault. Viruses and tampering are extremely rare occurrences when this happens; 99% of the time it’s simply a minor error or technical difficulty.

To ensure success when attempting an extraction, try adding a file extension first – if that doesn’t work, try changing it altogether.

This should solve any issues with 7-Zip not recognizing your archive type.

Solutions To Fix 7zip data error?

1: You Need To Update 7-Zip to the Latest Version

Updating to the latest version of 7-Zip can help you fix the ‘there are some data after the end of the payload data’ error.

To do this, open 7-zip and go to Help, then click About 7-Zip….

If your build number is older than version 16.02, head over to the 7-Zip download page according to your Windows architecture and install it.

Once downloaded, follow the on-screen instructions for installation.

It’s important that you update your version as soon as possible to ensure that all archives are being read correctly by the software.

Moreover, updating will allow you access to all new features that have been released since your current version was available.

Doing so helps improve efficiency when using 7-zip for archiving and compression tasks.

Remot your computer to complete the installation.

2: Rename the Extension from .zip to .rar

If updating 7-Zip to the latest version hasn’t helped, then try renaming the extension of the archive file.

You must first ensure the extensions are visible.    

To do this, follow these steps:

  1. Open File Explorer and go to View > File name extensions to ensure it’s checked.
  2. Right-click on the archive and select Rename.
  3. Change the extension after “.” from .zip to .rar and click Yes.
  4. Then right-click again and select 7-Zip Extract File.

3: Using Universal Extractor

Try using Universal Extractor (download link) to extract the archive file and avoid ‘there are some data after end of payload data’ errors. 

This method is an alternative approach that can be used if the two other methods previously mentioned have not been successful.

To use this software, download the UniExtract installer from the provided link and follow the instructions for installation.

Once installed, right-click on the archive file and select ‘UniExtract files.’ Then, select a destination directory to complete the extraction process.

Utilizing this tool should help you easily extract your content without receiving any error messages due to damaged sectors in your archive file. So give it a try today and see how it can make your life easier!

4. Just Ignore It

In some cases, you may choose to simply ignore the error. If the file opens correctly and you can verify its integrity with a tool like WinMD5Free, then there is no need for an alarm. 

This type of error often occurs because of a bug, not because anything is wrong with the archive or its files.

However, if this isn’t enough to ease your mind, consider downloading the archive from another source or opening files in a virtual machine instead. Here are some other options:

  • Use an alternate archiving tool to make sure that all data is properly stored and compressed.
  • Back up important archives so they can be retrieved in case of errors or corruption.
  • Unpack any archives on a different computer to check for compatibility issues.

Can I Ignore The “There Are Some Data After The End Of The Payload Data” Warning Message?

You can usually ignore the warning message about extra data after the payload. It doesn’t interrupt or negatively affect the archive and its files, so you don’t need to take action unless it’s causing an issue with extracting the file.

However, it may depend on what type of archive extension you’re trying to extract, as different types may require different actions. If you’re using a standard archiving format such as ZIP or RAR, then it should be safe to ignore this warning without any issues.

On the other hand, if you’re dealing with a more obscure format then additional steps may need to be taken in order for successful extraction. In any case, it’s best to read up on how to properly extract any given archive before attempting to do so in order to ensure that everything goes smoothly and without issue.

7-Zip Doesn’t Open ZIP files on my Windows 7. What Should I Do?

If you’re having trouble opening ZIP files on Windows 7, you can try running 7-Zip in Administrator Mode.

To do this, right-click the utility and select ‘Run as Administrator.’ Then go to ‘Tools,’ usually at the top of the app, and choose Options.

You’ll be able to change and alter File Associations and access other options. We recommend that you click the ‘Select All’ icon under File Associations.

This will let 7-Zip open all archives on your Windows system.

If this doesn’t work, make sure your computer is up to date with any available software updates or patches. It’s also possible that some virus protection or firewall settings are blocking your access to ZIP files.

Check these settings and if necessary adjust them accordingly before trying again with 7-Zip in Administrator Mode.

Why Is 7Zip Extraction Utility Not Working?

If you’re having trouble with 7Zip, it may be because your version is out of date. The latest version often contains bug fixes and other improvements to fix common issues.

To ensure that you are using the most up-to-date version, follow these steps:

  • Download the latest version from the internet
  • Install the update and restart your computer
  • Check if the issue persists after restarting

Once you have ensured that your program is up-to-date, if you still experience data issues when extracting files, try running a scan with an antivirus or antimalware program. Additionally, check for any corrupt files in the archive and make sure they are removed or replaced before attempting to extract again.

If all else fails, contact customer support for assistance.
