File Compression Methods

In file compression, there are two types such as lossy and lossless compressions. Let us discuss brief about them.

  • Lossy compression: It refers to data compression techniques in which some amount of data may get lost.  Lossy compression method attempts to delete redundant or unnecessary data. This lossy technique is used by most video compression technologies.
  • Lossless compression: Lossless compression rewrites the data of the original file in a more proficient way and no data will be lost. Due to this, resulting files are normally much larger than picture and music files compressed with lossy compression.

Basic Compression Techniques

  • Null compression
  • Run-length compression
  • Keyboard encoding
  • Adaptive Huffman coding and Lempel Ziv algorithms

Advantages of compressing files

  • Storage space: it saves disk space and that allows you to store more files. Zip technology reduces a file to approximately 50% of its original size.
  • Bandwidth and Transfer speed: In download process, network bandwidth is more important. Network bandwidth is used whenever you download or send a file such as MP3 music file. Bandwidth is the speed at which the network sends file and is measured in Mbps i.e. megabits per second. Compressed files include fewer “bits” of data than uncompressed files, and, as a result, use less bandwidth when you download them.

Disadvantages of compressing files

  • Memory issues: When uncompressing files and folders for writing or reading, your PC uses more space to complete the task. If you are running out of memory during uncompressing files then you may encounter one or more “Low Resources” or “Out of Memory” errors.
  • Speed: Uncompressing process also uses processor time. The processing time differs because of size and the technique used to compress the file. In addition, also running many applications on your PC during the uncompressing process makes the task run longer.
  • Virus and Malware: In PC, antivirus application may not able to scan compressed files for virus and malwares. If your compressed file contains virus threats and malware then it destroys your PC and results in loss of files.

As I said above if your compressed files contain virus threats and malwares, then it corrupts files and results in loss of files. Even while sending compressed files over network there are chances of files getting corrupt due to malwares. In such situations, one can make use of efficient third party software like Remo Repair ZIP (for ZIP files) and Remo Repair RAR (for RAR files) tools to mend your corrupted compressed files and restore lost files from them.
