Tips to Resolve “End of Extra data” in Zip file

An easy way to reduce or compress the size of a particular file is by using a Zip file. Zip file format is a popular method of keeping and transferring several related files together. But, sometimes when you further try to add extra data in the Zip file, the process might fail leading to Zip file corruption. In such cases, the data stored in the Zip file comes under threat as you may eventually lose your data. In such situations, you require a valid and updated data backup to restore the data. However, if the backup is found to be unavailable, incomplete or corrupt, then you will need to use a powerful Zip recovery application to repair the Zip file.

“End of extra data”

When this error message occurs, you fail to access the data saved in the Zip file. In addition, when you try to extract the files, you receive another error message:

“’The compressed size stored in the local header for this file is not the same as the compressed size stored in the central header”

You fail to extract the Zip files and eventually the data stored in the Zip file becomes inaccessible.

Cause:
Following can be the possible causes for the above issue:

The above error message indicates some problems or conflict between the local header and the central header, which is making the Zip file corrupt.
Another reason could be the large size of the Zip file, due to which the file gets corrupted and data becomes inaccessible.

Resolution:
To resolve these issues, you need to Repair Zip File to extract all the valuable information or data. A third-party application, known as Zip Recovery software will enable you to do so.

Errors While Inflating the Zip File May Cause Zip Corruption

Compressing the files and storing more than one files in a single archive is the best possible way to save disk space and easily transfer data through network. 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.

Grounds of the issue

This is a very common behavior of Zip file that takes place when Zip archive or the file gets damaged. Zip file corruption could the be outcome of missing parity bit, CRC errors, virus infection and many alike.

No matter what the cause of Zip file corruption is, the ultimate result will be data loss and that could not be accepted at any cost. At this point, it becomes extremely significant to resolve the problem as quickly as possible.

Resolution

In order to sort out the problem, restore the file from most recent backup. Zip does not provide any inbuilt tool to repair damaged files. If the backup is not available, then you need to go for third party applications to repair and restore damaged Zip file and extract data. These applications are known as zip repair tools.

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.

Corruption to the Zip file is a very serious situation as you might lose your valuable and mission critical data stored in the file. But you can handle such cases very easily and effectively through repair zip software.
