Using a zip recovery software to repair damaged ZIP file

On various occasions, you may have noticed that the ZIP files that you download from the Internet do not open in your system. This may be happening because of some incorrect download settings. However, some ZIP files do not open even on other systems as well. The main reason behind this issue is the corruption in the ZIP files that may have occurred while uploading them on the website. To overcome such issues, I would advise you to use a third-party ZIP repair software to repair ZIP file.

Let us take an instance in which you are using a Windows XP system and download a ZIP file from a website in Internet Explorer. When you try to extract the ZIP file by unzipping it, it fails to do so. An error message is displayed, which is:

“The Compressed (zipped) Folder is invalid or corrupted.”

Cause:
The root cause of such issues can be either of the following reasons:
  • You have not selected the 'Confirm open after download' check box.
  • The link that you have used to download the ZIP file uses either an ASP (Active Server Pages) page or a CGI (Common Gateway Interface) file AND you open the ZIP file directly from its location in the 'File Download' dialog box.
Because of these reasons, Internet Explorer does not save the ZIP file correctly in the Temporary Internet Files folder thereby making it corrupt.

Resolution:
To rectify this problem, you should try to download the ZIP file after performing the following steps:
  • Click the link for the ZIP file.
  • Click 'Save' in the 'File Download' dialog box to save the ZIP file to the hard disk. The 'Save As' dialog box will be displayed.
  • Provide a location to save the ZIP file.
  • Click 'Save'.
  • Open the file after it is downloaded and extract it.
If the ZIP file is still not opening, then it is already damaged. In such cases, you would need to repair the ZIP file using a third-party ZIP recovery software. These highly interactive tools are very easy to use and do not further damage the ZIP file.

ZIP file unable to extract after downloading from Internet Explorer 8

The ZIP files are used to compress the files and folders so as to encapsulate them into one single entity.
Using this phenomena, you can save enormous amount of disk space. One more advantage that these ZIP files provide that these are extremely handy and light when you have to transfer the data over the Internet. Also, these save you from the risk of virus infections as well. You can extract the data from the ZIP files using an extracting application such as WinZIP. However, when you are unable to unzip the ZIP file, it may be a possibility that the file is corrupt. If you are unable to repair ZIP file, then I would suggest you to use a professional ZIP repair tool.

Considering a ZIP corruption scenario in which you have downloaded a tutorial, which is in the form of a ZIP file from an e-learning website on Internet Explorer 8. After downloading the ZIP file, when you attempt to unzip it, you fail to do so. An error message is displayed in this respect, which is:

“The compressed (zipped) folder is invalid or corrupted.”

Cause:
You would receive such error messages if the HTTP (Hyper Text Transfer Protocol) compression has been turned on for the ZIP files on the Web server from where you have downloaded the ZIP file.

What happens is that when HTTP compression is enabled on the Web server, then the ZIP file is encrypted, after which it is sent to Internet Explorer. After getting the HTTP-compressed file, the ZIP file is transferred and downloaded to your system's hard disk. However, Internet Explorer does not decode the HTTP compression from the ZIP file when the unzipping application tries to unzip the ZIP file.

Resolution:
To overcome this problem, you should check if this ZIP file is available on any other website as well. If yes, then you should download the file from that link. The other thing that you can do is to use any other ZIP extracting application to extract the data.

If you are unable to extract the data from the ZIP file, then there is a need to use third-party solutions to repair ZIP file. These ZIP recovery tools are extremely non-destructive that do not overwrite or modify the ZIP files while scanning them.

The file extraction process happens but it results in a 0-byte file. Also, the 0-byte file is created in the target folder.

Note: You extract the ZIP file by either using the 'Extract All' option or by using a drag-drop on the ZIP file.

Cause:
Such problem is cause due to some bugs in Windows Vista Service Pack 1 version. The computer refers to these files as a 0-byte file as these files, being folder items, do not have the directory flag set in the external file attributes field.

Additionally, in Windows Vista SP1 the files are parsed first. Thus, the 0-byte files are created before the folders. Because of this, the extraction process fails as the folder structure cannot be created.

Resolution:
To resolve this situation, you should download and install the latest hotfix for Windows Vista Service Pack 1. You should ensure that you restart the system after installing the hotfix. Now, try extracting the ZIP file again. It should be extracted in the desired way now.

However, if the file is still not extracting properly then it may have got corrupted due to any of the aforementioned reasons. In such situations, you can download the ZIP file again.

If even that does not help, then you should look for other options such as a third-party ZIP repair utility to repair .ZIP file. The main advantage of using these tools is that they are non-destructive in nature that do not overwrite or modify the existing ZIP file.
