How does winzip compress files

When choosing the best file compression tool, here are some factors to consider:. There are several formats for compressing and decompressing files, and software compression tools can be compatible with one or more formats depending on their design and intended functionality.

A file compression tool performing lossless compression reduces the number of bits and bytes in a file to make it more convenient to store, transmit, and download.

Once it's downloaded, decompressed, and restored, the expanded file is unchanged from the original format. Lossy compression, on the other hand, eliminates unnecessary bits of information to reduce the output size. It's often deployed for media elements such as sound, pictures, and video.

Lossy compression is typically irreversible, so the compressed file won't be reproduced as it was in its original form. For instance, MP3 content is a common application of lossy compression. Typically, the digital material is condensed by eliminating some audio data from the original recording.

The compression tool will remove all sounds that are barely discernible to the human ear to reduce the file size. Storing loads and loads of data obviously takes up tons of space, so why not get the most bang for your buck?

Say you have GB of data you need to stash away on your computer, but your hard drive is only GB. Sure it will fit, but then you're left with only 50GB which isn't much these days. You could go out and buy a larger, more expensive hard drive, transfer everything from the old one to the new one, and be good to go. You still have all of your files, ready to use when you need them, but you don't have to spend any money on more storage space.

At this point, you should have a pretty solid understanding of file compression - how it works and why it's beneficial. That's great and all, but you probably want to know how to zip and unzip files yourself, right? The following is a crash course on the process of compressing and decompressing files.

Luckily, if the files you're trying to compress are relatively small, your operating system should be able to zip them without the need of 3rd party software. A simple right click option will take care of it for you. But what if you're dealing with several gigs of data? You're going to need something with more "oomph" to take care of things. Lucky for you WinZip is a leading file compressor. So, that about sums up the basics of file compression. It sounds impossible being able to reduce the size of a file, then put it back together in another location, but that's essentially what happens.
