Lossless Compression: This compression uses a process which compresses the files without any loss of data.

Transferring files over internet in an uncompressed format may corrupt your files.because, most email clients have size limitations of the email message, ion such cases you can compress the file and reduce the file size accordingly. Ease File Transfer: It becomes necessity while sending large documents over internet via email attachments.When a file(s) is compressed, the resulting “archive” file takes 50% to 90% less hard drive space compared to their uncompressed formats.

Reduced storage space: It reduces the size of a file (group of files), smaller than the uncompressed ones.

This helps you in transferring multiple files in a single command, instead of sending them one-by-one, many times, hence the transfer time is reduced.

Lessened transfer time: Compression / archiving of files will allow you to combine two or more files into a one single file.

The more times the word 'application' is found in the file, the more effective the compression will be. The main technique used in file compression is removing the redundant data from each file by replacing the common words or patterns with similar variables.įor instance, the word 'Application' may be replaced with the number 2, which takes less space than the original word. Each compression algorithm is different but they work in similar fashion. z etc.įile compression algorithm accepts one or more related files, combines them and reduce their size to make them more suitable for storage or transmission. Some of the file formats for compressed files are.

Each one of these compression methods uses a unique algorithm to compress the data. To perform this compression there are many tools available, some of the tools are WinZip, WinRAR, 7-Zip, ZipGenius and SimplyZip and Stuffit etc.

Once, a file is compressed, you need to decompress it and extract the files in order to read these files. It allows you to compress numerous files into one single file, which is smaller than the combined size of all the files. It works by reducing the redundancy in file’s code. File Compression is a process of packaging a file or folder (multiple files) into a compressed archive file which uses less space to store files on your hard drive.
