We explain how to compress files in Windows 10

Compressing files in Windows 10 is very easy, either natively or with third-party applications. The difference between some applications and others is -basically- the cost and integrity of the information, since many times in the compression process files can be corrupted and not work properly afterwards. Here, what really matters is the compression rate.

Have you ever wondered why only 15 songs come on a music CD, but 150 or more fit on the same CD in MP3 format? The answer is very simple: MP3 files, as well as most of the most used music, photo and video formats, are already compressed. Music discs use the CDA format and do not use any form of compression. Mystery solved.

To consider a compression rate acceptable, it must be at least 40% for it to be worth it. This rate does not depend on the program you use, but directly on the data you are going to compress. For example, if you are going to compress text files, Excel files, databases and in general, files that do not contain images, music or video, you can achieve a compression rate of 70% or more. While in images, music or video it would barely reach 5%, which means that it is not always worth compressing such files.

In any case, compression is useful for when you need to send a certain number of files and consolidate them into one. For cases of transferring files that are too large, there are special pages, although it is not recommended to send confidential information, even when they are automated processes.

In this guide, we will first show you how to compress a single file in Windows 10, and then how to compress a folder. After learning how to compress your files, we will show you how to open a ZIP file, so you can access the uncompressed files again. Let us begin!

Compress multiple files

This method is useful for grouping multiple files, both for size and organization reasons. This is a smart idea when packing files, but also to keep files together and free up disk space.
