Causes for Error “7zip Cannot Open File as Archive”

Most of us use compression software to save space and time while transferring or storing files. One of the popular and widely used compression software is 7zip. However, there are times when we encounter an error while trying to open a file using 7zip, and the error message reads – “7zip cannot open file as archive”. This error is frustrating, especially when we want to access important files. In this blog post, we will discuss some of the common causes for this error and how to fix it.

1. Corrupt File: The most common cause for the “7zip cannot open file as archive” error is a corrupt file. This can happen due to various reasons such as sudden system shutdown, virus or malware attack, or improper download of the file. When a file is corrupted, 7zip will not be able to extract the contents of the archive, resulting in the error.

How to Fix: In this case, unfortunately, there is no way to fix a corrupt file. You can try downloading the file again from its source and see if it opens with 7zip. If not, the file may be permanently damaged, and you may have to look for alternative sources.

2. Incompatible Version of 7zip: Another common cause for this error is using an incompatible version of 7zip. If you are using an outdated version of 7zip or the file was compressed using a newer version, you may encounter this error.

How to Fix: Make sure you are using the latest version of 7zip to extract the archive. If you are using the latest version, try compressing the file again using the same version. If someone else has compressed the file, ask them to use a lower version of 7zip or a different compression software.

3. Incorrect File Extension: Sometimes, the file extension may be incorrect, causing 7zip to not recognize it as an archive file. For example, if a file has a .zip extension, but it is actually a .rar file.

How to Fix: Rename the file and change the extension to the correct format. For example, change the .zip extension to .rar and then try opening it with 7zip.

4. Large File Size: 7zip has a limit on the size of the files it can compress and extract. If you are trying to open a file that exceeds this limit, you will encounter the error message “7zip cannot open file as archive”.

How to Fix: Split the large file into smaller parts and compress them separately. This will not only make it easier to manage the file, but it will also prevent any errors while compressing or extracting.

5. Damaged 7zip Installation: If none of the above solutions work, it is possible that your 7zip installation itself is corrupted. This could happen due to various reasons such as incomplete installation, virus or malware attack, or malfunctioning system drivers.

How to Fix: Uninstall 7zip and reinstall it from a reliable source. Make sure to download the latest version and follow the installation instructions carefully.

In conclusion, the “7zip cannot open file as archive” error can occur due to various reasons, including corrupt file, incompatible version of 7zip, incorrect file extension, large file size, and damaged 7zip installation.

Using Another App to Open Archive File

When it comes to managing and organizing digital files, archiving is an essential aspect. Archiving helps in storing and compressing files so that they take up less storage space, making it easier to manage and transfer them. However, sometimes we may encounter issues while trying to open an archive file, especially if we do not have the appropriate program installed on our device. In such cases, using another app to open the archive file can be a helpful solution.

Here are the steps to open an archive file using another app:

Step 1: Identify the file format

The first step is to identify the file format of the archive file. There are various types of archive file formats available, such as ZIP, RAR, 7Z, and more. Different apps support different archive file formats, so it is important to know the format of your file. To check the file format, right-click on the file and go to ‘Properties.’ Here, you will see the file type under the ‘General’ tab.

Step 2: Download an app that supports the file format

Once you have identified the file format, you can search for apps that support it. For example, if your file is in ZIP format, you can use apps like WinZip, WinRAR, 7-Zip, etc. These apps are easily available on their respective official websites or app stores. Download and install the app on your device.

Step 3: Open the app and extract the files

After installing the app, open it and navigate to the location where your archive file is saved. Most apps have a simple drag and drop feature, so you can drag the file from its location and drop it into the app’s interface. If not, you can also go to the ‘File’ menu and select ‘Open’ to locate and select the archive file. Once the file is selected, the app will automatically extract its contents.

Step 4: Save and access the extracted files

Some apps may ask you to choose the location where you want to save the extracted files, while others may save them in the same location as the archive file. Once the extraction process is complete, the app will open a new window showing the extracted files. You can now access these files as per your requirement.

Step 5: Change default app for opening archive files

If you want to use the new app as the default app for opening archive files, you can change the default settings on your device. Right-click on the archive file, go to ‘Properties,’ and click on the ‘Change’ button next to ‘Opens with.’ Select the newly installed app from the list, and click ‘Apply’ and ‘OK.’

In conclusion, using another app to open archive files is a simple and effective solution if you encounter issues with the default app or do not have the appropriate app installed. By following these steps, you can easily access and manage your archive files using a different app.
