As a computer user, we must have seen a number of files in which our crucial data and information are stored. A computer file could be small or large in size. A large sized file occupies more space in your system while small sized files take very less space. And due to having large sized files, it may affect your system performance or your system may become slow. But if you compress the files, they become reduced in size. 

A compressed file stores one or more files and it helps reduce resource usage, such as: data storage space or transmission capacity. Due to its compression feature, all your data are stored in a compressed form. Compressed file format is very common in downloading, transferring or sending and storing the data. Just have a look on some advantages of this format:

  1. Compressed files are small in size
  2. Due to small in size, they occupy very less space in the system
  3. They can be easily downloaded and shared over the network

A file which is used for data compression and archiving can be easily created by using a file compression tool. Some of the common tools are:  WinZIP, WinRAR and 7Zip. There are five common file formats, which are: ZIP (Zicxac Inline Pin), RAR (Roshal Archive), TAR (Tape Archive), TAR.Gz and 7z.

After compressing the files in any of the above formats, we need to extract data from it. You need the same utility to decompress the files. Unluckily if the files become inaccessible due to corruption, you cannot decompress or extract data from them. A lot of factors are there which can cause corruption, such as: virus attacks, faulty application, CRC failed, hard disk drive failure, using an invalid form of data in the compressed file and many more. 

If an archive file gets corrupted, you will receive an error message on the screen. Some of the common are: 

  • “The file or directory is corrupt and non-readable”
  • “Cannot open file: it does not appear to be a valid archive” 
  • “CRC (Cyclic Redundancy Check) error”

What can be done if a compressed file gets corrupted?

Whenever a compressed file gets corrupted, we have only three options to restore data from the file. If we have backed up the file earlier, we can restore it from the backup file. If no backup is available or if the backup file is itself invalid, you can download the file from the original source or recreate the file. If all these options seem worthless or fail to perform, you can try a third-party recovery tool. 

SysInfoTools Archive Recovery tool is the perfect solution to repair compressed archive files which are severely damaged or corrupted. It is one of the best recovery tools for corrupted compressed files because it supports multiple types of archive recovery, such as: ZIP, RAR, TAR, TAR.Gz and 7z. This software tool works in a self-describing mode, so it becomes beneficial for both technical and non-technical users.
