The Zip format allows to compress and archive large files by using compression algorithms. These files are mostly used over networks and secondary storage media like flash drives. A .zip file can get corrupted due to Cyclic Redundancy Check errors, improper system shutdown, malicious software like virus etc. Due to corruption in .zip file you are not able to access data stored in it. In such situations, you need to restore the data from latest backup. However, if there is no backup available then you need to repair the .zip file by using powerful Zip Repair tools.
Suppose, when you try to open a .zip file that you downloaded from an FTP site, you face the below error message:
"WinZip Self-Extractor Zip file is damaged, truncated, or has been changed since it was created. If you downloaded this file, try downloading again."
The above error message rises due to .zip file corruption. The data stored in the .zip file becomes inaccessible and you encounter the same error message each time when you attempt to open the .zip file.
Cause:
The above error message mainly occurs if WinZip self extractor finds a mismatch between file checksums. Another major cause is file system corruption.
Resolution:
The best possible ways to resolve the above error message are discussed below:
• Run the windows disk scan utility (CHKDSK). This utility enables you to repair the corrupted files.
• Delete the previously saved .zip file and download it again from the FTP site.
• Make sure that your internet connection is stable.
However, if the above process fail to deliver results then you need to use powerful and updated zip repair software. Such Zip Recovery applications use high end scanning algorithms that provide effective repair of corrupt .zip archives. These software come with user-friendly interface and simple, graphical and to-the-point documentation.
