Though, Zip file format is a useful compression method, at the same time it is vulnerable to corruption, due to which you might come across an error message while trying to open the Zip file. Sometimes, you may receive an error message after downloading the Zip file with Internet Explorer. This happens if the HTTP compression is enabled for the .zip file The reason behind such behavior may be corruption of the Zip file, as a result of which the data stored in the Zip file may no more remain accessible to you. In order to access your data, you need to have a copy of a data backup file. But, in case you have not backed up your data, then the only way by which your data can be retrieved is by using a good-quality zip repair application.
Consider a scenario Sometimes, when you download a Zip file using Internet Explorer 6 and try to open the Zip file, the following error message appears:
The compressed (zipped) folder is invalid or corrupted.
After this error message, you will not be able to access the Zip file. Consequently, all the data that was stored in the Zip file becomes inaccessible. Furthermore, you will not be able to open the Zip file, no matter how many times you try to do so.
The above mentioned error message occurs if the HTTP compression is enabled or activated for Zip files on the web server, from where the Zip file is downloaded. And if the HTTP compression is enabled on the web server, the Zip file gets encoded and then sent to Internet Explorer. When Internet Explorer receives the HTTP-compressed Zip file, then it is directly transferred to the program that is configured to un-zip the zip file without decoding the HTTP compression.
To resolve the issue, you need to repair zip file using a third-party application, known as zip repair software. These application are specially designed to resolve all the corruption issues associated with Zip file format. In addition, these tools are embedded with highly intuitive and innovative graphical user interface that makes them user-friendly and hence do no require any prior technical knowledge.
