To access data from the Zip file, you need to extract it. Sometimes, while extracting the Zip file, the process may fail due to list index of the file and it may become inaccessible. Such behavior of Zip file results into critical data loss situations and requires Zip Recovery to be fixed.

When you attempt to extract a Zip archive or Zip file, you might encounter the below given error message:

“List index out of bounds (502139)”

After the occurrence of this error message, the Zip file extraction process gets halted. In this case, the data stored in the Zip file can not be accessed and critical data loss situations take place.
At this point, you need to identify the root of the issue and carry out Zip Repair. It is essential to gain access of your data.

Grounds of the issue

This problem may take place due to some issues with catalog files of the Zip archive. It does not let the extraction procedure complete successfully and shows you the above mentioned error message. The problem may occur due to the missing required data in catalog file of Zip archive.
The ultimate result of Zip file corruption would be the loss of your mission critical data. You need to retrieve the lost .zip file data to overcome the data loss.

Solution

WinZip does not offer any inbuilt utility or tool to repair and restore damaged Zip archives. Therefore, you need to opt for powerful and advanced third party Zip Recovery applications to sort out such issues.

Zip Recovery in Case of Unsuccessful Extraction Due to Corruption

Zip is a popular file compression file format. It allows you to compress several files in a single archive or file to save hard drive space and easily transfer the files over network. Before you access data form the Zip file, you are required to extract it. But in some cases, the extract can not be successful due to corruption to the Zip file or invalid compression technique. In such cases, the data from Zip file can not be extracted and you come across data loss situations. In these circumstances, you need to carry out zip recovery to repair and restore damaged Zip file and extract data from it.

In a practical scenario, when you try to extract a Zip file to access data from it, you might come across the below given error message:

“Database and data store files were not successfully extracted from zip file. Error inflating: oversubscribed dynamic bit lengths tree”

You might also get this error message when you attempt to unpack a zipped database that has been stored remotely. In such cases, this problem might occur due to some network problems.

Such behavior of Zip file might also occur due to Zip file corruption. It is potential that a Zip file that you are try to extract and access data from, has undergone corruption due to a number of causes such as application malfunction, virus infection, CRC errors, improper compress and many other similar reasons. This behavior and error message occurs every time when you try to extract the Zip file.

So it is required to find out a solution that could actually help you to extract damaged Zip file and retrieve data from it. The solution must be able to benefit you the Zip Repair.

These software are known as zip repair tools, which use high-end scanning tools to methodically scan the damaged Zip file and extract it. These tools are complete safe and easy to use.

Zip Corruption Due to Incomplete Inflate Process or Invalid Data

Zip files are the repository of compressed data. These files are created using WinZip utility. You can compress any sort of files in a single directory and can easily transfer it over network or save it to hard drive. But in some cases, the Zip file might get damaged and you can not access data from it. The damaged Zip file is a decisive state to be tackled by the Zip Recovery software. The corruption to the Zip file is indicated by various error messages. The corruption could take place due to invalid objects in the file or compression technique.

In order to access data from a Zip file, you need to extract it. After extraction, a new folder is created with the same name as of Zip file and that will be accessible as a simple folder in Windows. But when a Zip file gets damaged, it could not be extracted and the stored data can not be accessed from it. The major contributing factors of Zip file corruption are virus infection, application faults, CRC errors and so forth. Zip Repair is required to handle corruption circumstances.

In a practical scenario, when you try to extract a Zip file to access its data, you might come across the below given error message:

“Invalid Compressed data to inflate”

In a Zip file, the deflation is a compression algorithm that I used to dense the files and directories in a Zip archive and this is used in several file versions of Zip. When you try to extract the Zip file, this is inflated with reverse process. Failure to inflate the Zip file due to damage or any other reason such as version mismatch could give you the above error.

Compression is also helpful for effective and easy backup of data. Most of the system administrators as well as home users use this method for different purposes and Zip is the most popular compression technique. In this method, the file is saved in the form of Zip format and for accessing data from it, you need to simple extract it. But in some cases, when you try to extract or unpack zipped database, process could not complete successfully and thus data becomes inaccessible. This behavior of Zip file results into critical data loss situations and require Zip Recovery to be sorted out.

Sometimes while extracting the Zip file, you might come across the below given error message:

“Database and data store files were not successfully extracted from zip file. Error inflating: oversubscribed dynamic bit lengths tree”

After above error message, the extraction process gets halted and thus you can not access data from the file. These circumstances cause critical data loss situations and require you to find out the cause of this problem and carry out Zip Repair by resolving it.
