Most hard drives and SSDs nowadays have larger storage spaces and are cheaper. This makes most of us think that there is no need for tools like file compression apps. After all, your external storage space can store all documents and media files, no matter how large they are. But, file compressing programs are still very much needed for two important reasons. One, compressed files do not take up a lot of storage space. Two, compressing protects your files through passwords and encryption. Additionally, compressing make it easier and faster to send files using the internet. 7-Zip is a free, open-source file archiving software that lets you compress and decompress files. This utility application offers a high compression ratio and comes with several features that can match the best compression software available today. 

Compressing and Decompressing Files

Whether you want to save storage space or secure your files, 7-Zip has got you covered. This software is tiny but it has all the support you will need to create numerous other types of compressed files including 7z, BZIP2, and TAR. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10% better than other compression apps. This ratio is 40% higher than other compression tools such as PKZip. 7-Zip uses LZMA and LZMA2 compression, with dictionary sizes and strong compression setting, to improve density.

However, this makes the compressing time a little slower. Compressing your files using 7-Zip takes more time than other similar apps. Moreover, compression carried out by 7-Zip may also need a lot of system requirements while in progress. But, while it may take a while to complete a compression task, you are assured that the app won’t damage the file you zipped.

Besides its use as a file compressing program, 7-Zip is also one of the easiest decompression software. You can use this app for both unzipping the files and creating archives, even though it does not support a large number of unzipping formats like PeaZip. However, the program can be integrated into the Windows Shell, providing a straightforward way to extract and archive files by right-clicking. 

Additionally, 7-Zip comes with a built-in file browser that can locate and extract archives. It adheres to most Windows explorer standards, and even displays hidden files. In addition to zipping and unzipping file archives, 7-Zip also allows users to add password protection to their compressed files. 

User Interface

7-Zip comes in a simple interface that many users may find dated. However, this basic-looking design makes it easy to navigate around the app. It comes with the main toolbar that contains the most used features and several menu options that let you customize. For example, the extract button lets you set your file's destination directory, while the view menu lets you access your folder history. There is also the favorites menu that allows you to save up to ten folders.

There are two ways to use 7-Zip. First is to open the main program window and work with your compressed files through the file manager. The second one is the context menu which gives you access to a key set of features by right-clicking your files

Using the file manager can be a little confusing, especially for new users. Unlike most compression tools, you cannot add a file to an already compressed folder. You will need to begin again whenever you have to add a new file. 

Additionally, 7-Zip’s configurable settings will likely put-off most novice users. The app provides little explanation for the many options they provide. If you are not familiar with file compression programs, you will probably settle for the default setting just like most people do. 

If you want a more user-friendly way to work with 7-Zip, you can use the context menu. This menu integrates the key features of the app to the right-click option of your device enabling you to add your files to the compressed archive in a few clicks. You can also use other options such as zipping the files and adding them to an email saving you more time than fumbling around the file manager.

7-Zip also integrates with your Windows Explorer menus which displays your archived files as folders and providing a toolbar with a drop-and-drag function. It also allows you to alternate between a single or a dual-pane view

Other Features

7-Zip comes in a feature-rich design that can give popular file archiving apps such as WinRar and WinZip a run for their money. For one, it is a free application with an open source, which means you can download and install it on your device without registering or paying for the app. The source code uses the GNU LGPL license, while the unRAR code is under a mixed licensed of GNU LGPL and unRar restrictions

In addition to its high compression ratio, 7-Zip also boasts a strong AES-256 encryption feature which includes both password protection option for your files and encryption of file names. The app also supports self-extracting capability for 7z format and comes with a powerful file manager and command line versions. 7-Zip also comes with a plugin for FAR manager

Furthermore, the app comes with a language localization option. It allows users to switch the app language to the language of their choice. 7-Zip supports 87 languages, so you are sure to find a language that you are comfortable to use.

In a Nutshell

If you are constantly saving and sending large files, then maybe you need to have  7-Zip installed in your device. The app is easy to use and works well with Windows Shell. It supports a wide selection of formats and can read zipped files created from other file archiving tools. The app also utilizes strong encryption and provides an impressive compression ratio. More, it is free for both personal and commercial use. No registration and monthly subscription needed. So, if you are looking for a cost-efficient and convenient way to zip and unzip files, 7-Zip is the right choice for you.
