Part 5. Extended Knowledge on File Compression

1. What is a file compression

As we have stated above, file compression in the simplest terms is the process of reducing file size. The main compressed file can be termed as an archive, which has a number of files with reduced size. The compression process results in a smaller file size by replacing the character sets with small-sized placeholder characters. File compression is mainly of two types- lossless and lossy. Lossless compression is the process where there is no loss of any information, whereas, in lossy compression, not so important parts of the file are chopped.

2. Benefits of using file compression

There are many wonderful uses of compressing files. Read below to know more.

  • Easy file sharing and transferring
    Compressing files to smaller size makes them easy to transfer through emails and share online and through social media. There are many email clients where there is a restriction on the file size, which can be transferred. Moreover, large files not only affect your bandwidth but are also difficult to manage. In all the above situations compressing files proves to be the best solution.
  • Secures file sharing
    In case if you have confidential and important files, you need to ensure their safety before transferring or sharing. File security is taken care of while using compression software like WinZip as it encrypts a file before it is sent to mail or cloud storage. The multi-part compression further adds to the security of the files.
  • Archives files and saves disk space
    Compressing files helps in archiving old files that are not in use. A large number of files on your system can run out of your valuable disk and storage space. If you analyze, there is a long list of files like your favorite movie collection, which is currently not in use but grabbing up a lot of your hard disk space. You can simply compress and archive these files to release some burden from the disk.
  • Save money
    It may sound absurd, but compressing files can also help you save money. A lot of files mean a need for large storage space, which would lead to buying a hard disk with more capacity. Buying a hard disk is a pricey affair, and thus if you compress files, you can save storage and prevent from buying a larger sized hard disk.
