Extract Your Maximum Data From Corrupt ZIP Archive

Compressed file format is one of the best options for data storage and data transmission. A compressed archive file can contain one or multiple files in a compressed form. The compressed files help you save your hard disk drive space. These files take less space to be stored in the system than other computer files. They can easily be shared or transferred over the network. If you want to send or transfer a large file over the network, then you can take the help of a compressed format.

ZIP or Zicxac Inline Pin is a popular archive file format, which can contain multiple files and folders in compressed form. A ZIP file generally uses “.zip” as a file extension and can be created by using WinZip and WinRAR compression utility. But sometimes a WinZip or WinRAR utility may fail to extract the ZIP archives. The key reason behind this situation is corruption. Corruption has always been an unpredictable issue for computer users.

If you are a regular user of ZIP archive files, then you must have faced a situation like this: you have downloaded a ZIP archive file from the Internet or one your friends sent it to you via email. You have an installed WinRAR or WinZip program in your system. But when you try to unzip the file, your WinRAR or WinZip program fails to extract or open it. File corruption could be the main reason behind this situation. Or sometimes it may happen that you have created a ZIP archive in which you have stored a number of files. To save the hard disk drive space you have deleted the original files and you have no backup file of those deleted files. The problem starts when you find that the ZIP archives created by you cannot be opened or have become invalid due to corruption. This must be a very frustrating situation for you. The ZIP files are corrupted and you have nothing to restore the lost or corrupted data. You have already deleted the original files and you have not created backup file for them. What will you do in such a critical situation? If the corrupt ZIP files are downloaded or received, then you have a chance to get them back again from the same source. But sometimes this could be impossible if the files have been removed or deleted from the original source. In such situation you need to repair the files or recover data from them.

A ZIP archive can be easily corrupted or damaged due to several reasons. Some of the common reasons are: virus attacks on ZIP archives, unwanted interruption in downloading, storage media crash or failure, sudden power failure while creating or extracting archive file, etc. Due to all these factors a ZIP archive file may become inaccessible and you cannot extract any data from it. You must repair a corrupt archive file before you extract it. To repair a corrupt ZIP archive you can use WinRAR program. It has a built-in repair feature that is used to repair corrupt ZIP as well as RAR archives. The following steps are mainly required to repair a corrupt archive by using WinRAR application:

  1. Open your WinRAR application in your system.
  2. Now click on File tab > Open. Or you may simply press Ctrl+O.
  3. A small window “Find Archive” will pop up. Locate the corrupt ZIP archive from your system directory and select it.
  4. Now click on Open button.
  5. Click on Tools tab > Repair archive. Or you may simply press Alt+R.
  6. Again a small window “Repairing File name.zip” will pop up.
  7. Now click on Browse to select a location to save the repaired archive.
  8. Check the box “Treat the corrupt archive as ZIP” and click on OK.
  9. WinRAR will start repairing of corrupt ZIP archive. Once it gets completed click on Close.

The selected archive file would have been repaired successfully. You can check the file at the location what you have allocated earlier. But sometimes WinRAR fails to repair archives if they are extremely or severely corrupted. In such situation you can use third-party ZIP recovery software that will help you recover your inaccessible or invalid data from corrupt ZIP archives. The third-party ZIP recovery software applications are available with free demo version. Demo version is used to examine the performance and capabilities of the software before buying it. You must check demo version of any third-party ZIP recovery software and it satisfies your need, then you can buy its full version.

Zip File Decompression

Zip files are compressed files that can contain either one file or many files of various sizes in them. The benefit here is that you can combine multiple files into one compressed file which is known as an “archive.” The only way you can open and extract the contents of an archived file is if you have zip software which has the ability to compress and decompress them. Some of the most popular zip software programs include WinRAR, WinZip and 7zip. But chances are you already have zip compression software if you are using Linux, OS X or Windows operating systems. The newer versions of these operating systems come with zip software, but you can also download third-party programs if you prefer to use a different program to open or compress them.

Here are the basic steps in obtaining and using zip software to extract contents from these files:

1) For starters, if you have purchased a new computer within the last ten years then it should have some kind of zip software on there. If for some reason your computer doesn’t have zip software built-in to its operating system then you can search Google for 7zip, WinRAR or WinZip, and then go to the website of the one you are interested in. 7zip and WinRAR are free programs, while WinZip comes with a free trial where you will eventually have to pay for it after a certain amount of time.

2) When you are ready to extract the contents onto your computer, it is very simple to accomplish this task. All you have to do is right-click on the file and then choose either “Extract Here” or “Extract All.” Extract Here places all of the contents into the same folder as the zip file. Extract All allows you to create a separate folder for the extracted contents to go into.

3) If you are using 7zip then you will have the ability to unzip multiple zip files in one shot. This is great for people who frequently download zip files or have a lot of zip files that they want to unzip at the same time. What you do is highlight all of the zip files with your mouse, right-click within the highlighted area, put the cursor on 7zip in the drop down menu, and then choose ‘Extract to “*/”‘ You will be able to extract all of the contents of all the zip files into their own separate folders that have the same names as the original zip files in which they came from.

How to Zip a Folder?

When you have a large number of files, each with considerable text and image content, you cannot handle them efficiently and they are likely to get corrupted. They cannot be copied to other storage mediums quickly and email software can prevent them from being sent because their size is too large. In such situation, it becomes necessary to compress the file so that it is more manageable.

File compression helps to save disk space. For example, when you have a set of large PDF files or word files, zipping them reduces the space they take up. They are easy-to-handle and you can send them through email without having any problem because of file size. Many a time, you might have to copy a large set of files to another storage location. If they remain large-sized, it becomes difficult to perform the copying successfully and quickly.

File compression can be done through compression or zipping software. There are many types of file zipping software such as WinRAR, TurboZIP Express, 7-Zip, BitZIPPer, QuickZip, ALZIP, WinAce, IZArc, and Stuffit. You can use file zip software to not just compress a single file, but several files and put them into a single zip folder.

Alternatively, you can also zip an entire folder, which has all the files you want to compress. Here is a look at the steps involved in zipping a folder that contains a large number of files.

• Open WinZip application. If the license window appears, agree to its terms to proceed further.
• Click ‘New’ button to create a new archive (.ZIP).
• Enter the destination of the folder file in the ‘Filename’ box. Specify the name of the folder and click ‘OK’
• Click the ‘Add’ button and create a compressed form of the specified folder.

A shorter way to zip a folder is to right click on the folder and specify ‘Add to WinZip’ to begin the compression process. You have to follow the same procedure as mentioned above to create a compressed version of the folder.

File zipping is a task that should take you just a couple of minute’s time. WinZip is the most common software used for file compression. If you are interested in using any other application for zipping folders, select one that is easy-to-use, which offers a friendly user-interface and which can provides various options. It should be able to extract file, archive them and also provide encryption features through which a folder is password protected.
