WinRAR is a file compression utility that helps to reduce the size of the file by reducing unnecessary amount of information from a particular file. It has highly compression algorithms which help in breaking a compressing file into sub files. Sub files are the smaller segment of the main file which can be rearranged during decompression process. It has the unique ability to create self-extracting archives. WinRAR helps to squeeze a larger file which makes data transferring and sharing process much easier. The major difference between WinRAR and WinZip is that WinRAR is a shareware program whereas WinZip is freeware program which comes by default by Windows Operating System. Other than this, most of the features of WinRAR and WinZip are same. It is the most efficient tool for zipping and unzipping RAR and ZIP files.

It supports files and archives approximately to 8,589 billion gigabytes. It has an extraordinary feature of reconstructing physically damaged archives. Therefore, WinRAR features are getting upgraded day by day in order to hold number one position as file compression utility. As we know that WinRAR helps to zip and unzip RAR files, sometimes even this compression utility will not be able to compress and decompress RAR files because of RAR file corruption. The reasons for RAR file corruption are many but the most prominent one are as mentioned below:


Interruption during downloading process - RAR file structure gets damaged if any disturbance occurs during downloading any RAR file. Interruption occurs due to power failure, system failure or abrupt shut down of the system. It is essential that downloading process is executed without of any hurdles. Once any interruption takes place, then your RAR file is likely to get damaged. Use professional RAR repair application in order to fix corrupted RAR file.

File extension alteration – It is one of the most critical reasons for file header corruption. Making any changes or alteration to the file extension can corrupt your RAR file. Generally, if you rename a file extension from ‘abc.jpeg’ to ‘abc.rar’ will affect the file structure of that particular file and create a problem in accessing it. Due to this reason your file becomes unusable and will not function as a RAR file.

Physical damage to the storage disk – Storage disk helps to store a large number of compressed files and other data. But sometimes it may happen that you are not able to store a particular file to the storage due to some problems. These problems can be physical damage such as cracks in the disk or due to the exposure of the disk to the liquids. Due to these damages your RAR files might get corrupted


However, you can always prevent your RAR files from getting corrupted by following some of the precautionary measures which are as follows:


  • Check your network connection before downloading RAR files from internet. If any interruption takes place because of network connection at the time of downloading RAR files then there are lot of chances that your file may gets corrupted.
  • Never ever change file extension of any RAR files until and unless it is required and you know the proper methods of changing file extension.
  • Never use unreliable third party application for unzipping RAR files or for changing file extension.
