How To Recover Data From Corrupt ZIP, RAR, TAR, TAR-GZ and 7z Files

Compressed files are the most common and safe way to reduce the files size, store and send them over the network. They are small as they are compressed by a safe compression algorithm. This technique is very safe as it only reduces the file size, it does not alter or modify the data. The files which are in compressed file formats take less space in our system hard disk and due to compressed form they can be easily shared or transmitted over the network. We usually compress our computer data to get more free space in our hard disk and by doing this we can easily and quickly share them via email.

Generally there are five main compressed file formats:

    ZIP: ZIP stands for Zicxac Inline Pin is used for data compression and archiving. It can contain one or many files in compressed form to provide more space in hard disk and good transmission speed. It can be easily created by WinZip or WinRar program.

    RAR: RAR stand for Roshal Archive is the best data container to store various files in compressed form. We can create a RAR file with the help of WinRar program. It has some more advanced features than ZIP archive.

    TAR: TAR stands for Tape Archive is actually not a compressed file format however it is known as a compressed file. It is commonly used to store many files into a single large file. It is best known for archiving files in Linux operating system. It can be created by using TAR program.

    TAR.GZ: It is the most common compressed archive file format in Linux operating system. It is much better than TAR file as TAR file is archive file format while tar.gz is a compressed archive file format. It is not only used for archiving but also for data compression. It is also created by TAR program.

    7-z: It is one of best archive formats with a high-compression ratio. We can easily compress files up to 16000000000 GB of size. 7-Zip program is mainly required to create 7-z files.

But unfortunately none of them are immune to corruption. All these files are prone to high level of corruption as corruption is an inevitable occurrence. They can be easily corrupted at any point of time and in this circumstance we cannot extract our data from it.

There are various unavoidable reasons which are mainly responsible for the corruption in these files, such as:

    Computer bug and viruses are very harmful for our files. They can easily damage our files and make them unusable or corrupted. If a compressed file is damaged by virus attack then it becomes inaccessible and unable to be extracted.

    These types of files get mostly corrupted or damaged while sending or downloading through internet. Bad or weak network connection can easily damage our files and make them corrupted.

    If we have used any faulty or outdated program to compress our files then it could be corrupted or damaged and the data can be lost forever. And sometimes mistakenly we add some invalid data in our compressed file and this can damage our file.

    As we know that our files can be damaged or gone if our system crashes down or error occurred in system hard disk. It happens due to bad maintenance of hard drive or any mechanical problem in it.

    While opening a file or extracting data from it if our system suddenly turns off then this can damage the file or make it corrupted.

In all these critical happenstances we cannot open our files and data cannot be extracted from them at any cost. But we have a valid backup then we can restore the backup copies of our corrupt files from it. But if we do not have any backup then we must not worry as one more solution is still there. We can use a third-party tool to recover our data from corrupt compressed files. But before using any third-party tool we must use its demo version to check its performance. Generally demo versions are free which can be easily downloaded from the website.

Generally most third-party tools only support one or two files recovery. But if we have several compressed files of more than two file format, i.e., ZIP, RAR and TAR then it will become little difficult for us. We need to buy more than one tool to recover data from corrupt files which must be little expensive. But there is a tool named as Archive Recovery tool which supports all five file formats, i.e., ZIP, RAR, TAR, TAR.GZ and 7-z. By using this tool we can easily recover our data from corrupt compressed file of any format.

Archive Recovery tool is multipurpose tool offered by SysInfoTools at very affordable rate. It is only tool that supports all five compressed archive file formats. Due to this it is highly recommended by most computer experts and many satisfied users. It can easily recover data from a large corrupt archive file, i.e., one TB. If corrupt archive files are stored inside an external storage device it will recover the data from it. And to check its features and high performance we must use its free demo version.
