Summary: Learn how to extract data from corrupted zip on your Mac using default utilities to downloading specific recovery tools like Stellar Data Recovery Professional.
Using ZIP files allows the user to compress and archive files for easy storage and distribution. But ZIP files can be easily corrupted for several reasons, like broken downloads, sudden system shutdowns, or failed hardware. If a ZIP file is spoiled, it may be impossible to unzip files inside.
However, various recovery utilities & methods exist to retrieve data from corrupted ZIP files, depending on the enormity of the corruption. This article will explore the most typical methods to extract data from corrupted ZIP files on Mac.
What is the Corrupted ZIP File?
A corrupted ZIP file is a ZIP archive that carries errors due to loss of integrity and interruptions during the compression or extraction process. For instance, when the ZIP corrupted data can no longer be opened or extracted correctly, it means that it is damaged or lost entirely. How can you tell that a ZIP file is corrupted? Usually, signs of corruption appear as error messages, missing or non-readable documents, and unstructured content within the ZIP file.
How Does a ZIP File Get Damaged or Corrupted?
A ZIP file can become corrupted via several causes. Some of the most common reasons include:
- Transmission errors might occur when a ZIP file is being downloaded or uploaded on the internet or while moving it from one device to another.
- Power outages or other unexpected interruptions: If the zipping or unzipping process is interrupted in a way that was not expected, the ZIP file may end up being corrupted.
- Virus or malware infection: A ZIP file can be infected with a virus or malware and become damaged to an extent where it cannot be opened or extracted.
- Physical damage to the storage device: When the storage device carrying the ZIP file is physically damaged, the file will also be corrupt.
- Software bugs: The file may get corrupted if a software bug exists in the ZIP compressor or extractor tool.
How to Extract Data From Corrupted Zip on Mac?
Now, let’s talk about several ways to extract your data from a ZIP file that was damaged or corrupted.
1. Download File Again
First, check if the ZIP file is really corrupted. Sometimes, the issue may be due to incomplete downloads or other factors. In that case, try downloading the file again or getting a copy from a reliable source so that it can be excluded.
2. Use Reliable ZIP Software
Make sure you have reliable ZIP file extraction software installed on your computer. Popular choices include 7-Zip, WinRAR, or WinZip. These tools often have better error-handling capabilities than the built-in extractor.
