Let us know about Data Compression

Over the last two decades, data compression has become very popular. It has various amazing benefits. I’ve listed a few below:

  • If you use data compression, you’re going to save your disk space for sure. Just don’t worry about the integrity of your data. It’ll remain intact.
  • If you use data compression to compress your files, you’ll get an excellent file transmission speed.
  • And, if you want to secure your data with password protection, you can do that. Most of the data compression tools provide password protection feature.

Almost every computer user is using data compression these days. There are many types of data compression, and the ZIP is quite popular. It’s an archive file format that supports lossless data compression. In a ZIP archive file, you can store one or more files or directories in compressed form. As far as my knowledge goes, data compression has only one major drawback.

Data Corruption in ZIP files

If you’re using ZIP or any other type of data compression, you just can’t avoid corruption. A ZIP archive file is prone to corruption due to numerous reasons. The fact says nothing can be extracted if the ZIP file is corrupt. The most common reasons for corruption in ZIP archive file include virus infection, bugs attacks, software malfunction, hard disk failure, abruptly system shutdown, adding invalid content to a ZIP archive file, network failure, etc.

How to Deal with ZIP file Corruption?

Whenever corruption takes place in the computer files, it puts your data at high risk of loss. If the ZIP file is corrupt, you’re likely to lose your data if you don’t repair ZIP file in time. Before you can try anything to repair ZIP file, you should use the backup file. If you’ve taken the backup of your ZIP files earlier, you can restore them from the backup file with ease. But if there’s no backup available, you should consider using a professional ZIP Repair tool. There are many vendors in the online marketplace which provide 3rd party ZIP Recovery software. A professional ZIP Repair tool can repair ZIP file and recover your maximum possible data from it. But no such 3rd party tool is available for free. So if you’re looking for a free solution, you should use the WinRAR application.

How to Repair ZIP File?

Before purchasing any paid ZIP Recovery solution, you should use an easy DIY trick that requires no cost. All you need to use is the WinRAR application. It has a built-in repair feature that can be used to repair ZIP file. First, launch the WinRAR application on your computer and follow these simple steps:

  • Click the File menu > Open archive. Or simply press Ctrl + O.
  • On the Find Archive window, locate the corrupt ZIP file archive and select. Now click the Open button. You can see the corrupt ZIP archive file is listed on the main screen.
  • Click the Tools menu > Repair archive. Or simply press Alt + R.
  • A small window will pop-up, FileName.zip. Click the Browse button to define a location where you want to save the repaired archive.
  • Now define the archive type. Since you want to repair ZIP file, select the Treat the corrupt archive as ZIP option. Click OK to start the repairing process.
  • Within a couple of minutes, the repairing process will be completed. Finally, click Close.

Extract Data from ZIP Archive

The WinRAR application has one more built-in feature, Data Extraction, which you can use here. Follow these simple steps:

  • First, launch WinRAR application on your system.
  • You need to locate the corrupt ZIP archive file, but don’t open it. Right-click the file to select it in the list.
  • Now click Extract To on the taskbar.
  • On the Extraction path and options dialog box, define a location where you want to decompress ZIP archive file. Define settings and other options as per requirement.
  • Under the Miscellaneous section, check the Keep broken files option. Click Save Settings button.
  • Now click OK to start the data extraction process.

I personally don’t recommend this trick if the ZIP archive file contains large executable files of software applications. But if the ZIP archive file contains images, audios, videos, emails, documents, and any other files, the above trick will definitely help you.

Note: I don’t guarantee that the above DIY tricks will surely work for you. But there’s no harm in trying them.
