Why compress a file

For example, we've all been at work and been sent a spreadsheet, document or presentation that has blown our mailbox. We've all visited websites that seem to take an age to load and that's because the images used on the site are unnecessarily large in size.

Sometimes, there's a requirement to have the highest quality file possible - perhaps a wedding picture you want printed or a movie that you are airing. However, most of the time we want to be able to send files quickly and to also be able to consume them easily. This is why we have built the Zamzar compression tool. We are able to compress all different types of files - Images, Documents, Videos and Audio files - and allow users to make those files smaller whilst still retaining their overall quality.

File compression can be date back to about half a century ago. In the s, computer scientists strived to find ways to reduce the file size and they succeeded—searching through computer code by using mathematical algorithms. With the development of the Internet, the need for creating better compression schemes and reducing the size of files as much as possible keeps climbing.

What can you benefit from compressing a file? This could help you understand why you enjoy the following benefits after file compression. What is file compression? File compression is the act of reducing the size of a file while preserving the original data. So, compressing a file will retrieve the space on a storage drive. Why does a file become smaller after compression? Do you know the working principle of file compression? File compression utilizes compression algorithm that is a mathematical formula used in compression and decompression of an electronic data file.

There are two types of compression algorithm:. Lossless: By this type of file compression, a decompressed file has the same size as the original file. Stated another way, there is no detail or content lost in the compression-decompression process and you can perfectly reconstruct the original file.

But how does this type of file compression reduce file size? Simply put, lossless compression stores the same information in a more efficient way by removing redundancy.

For example, uuuuummmmoooooo can be shortened as u5m4o6. There are rare lossless formats for video since they would take up massive amounts of space. Lossy: By this type of file compression, a decompressed file is smaller in size than the original file.

This compression type is most common in the image, video, and audio formats, where a perfect representation of the source media is not necessary. Should I use lossless or lossy compression? This depends on what you are using the files for. In general, if you desire a perfect copy of the source material, you should use lossless compression; while it is wise to use lossless compression when a copy of the source material is good enough even if it is imperfect.

Can I convert lossless formats to lossy or lossy format to lossless? It is fine to convert lossless formats to lossy, whereas converting lossy formats to lossless is simply a waste of time. When you compress using the lossy compression, unnecessary information is taken out. In flows with big media files and few participants, it often pays to download the files one at a time. Uninstall unnecessary apps and programs. Clean your desktop. Get rid of monster files. Use the Disk Cleanup Tool.

Discard temporary files. Deal with downloads. Save to the cloud. You are running out of disk space on Local Disk C:. Click here to see if you can free space o this drive.

If your C drive is filling up without a reason, it can be due to a malware attack, file system corruption etc. The C drive is usually taken as the System partition on a computer system.

Having some free space in your C drive is essential as it is often needed during a Windows update or upgrade. This disables the compression. To enable it later again, run again powershell as admin and run the Enable-MMAgent -mc command. No jargon. Pictures helped. Didn't match my screen. Incorrect instructions. Too technical.
