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.
