In this article, we will explain the ways to compress files in Windows and Mac to simplify your computer system's disk drive. But before let's grasp the understanding of File compression and why we need this.

What is File Compression and its various methods?

File compression is a process to decrease the file size to use less disk space. This process is used to send a file from a computer to another with a limited connection bandwidth. File compression is performed by the following methods:

Lossless Compression

This method uses data compression algorithms that enable the original data to be restored from the reduced data. Lossless file compression compresses a file without degrading its quality. Moreover, this compression uses Run Length Encoding (RLE), Huffman Coding and Lempel-Ziv-Welch (LZW) algorithms.

Lossy Compression

This method results in degrading data and quality from the original version of the file. This procedure is related to JPEG image format and audio files like MP3s or AAC files. Moreover, lossy compression uses fractal compression, Transform coding, DWT, RSSMS, and DCT.

Now, we will share the method to compress files in different Operating Systems.

How To Compress Files In Windows?

Here is the good news for newbies, who wish to learn file compressing in an easy method. Windows 10 comes with the support of file compression. So you don't need any third-party applications to reduce the file size of your document. Follow the steps below to start the procedure:

What are the common image formats and best uses:

BMP

BITMAP (BMP) files are the image format that is used by Microsoft operating systems. We can't use BMP for web purposes. These BMPs stores color data of each pixel image without compression. A bitmap is also called a raster graphic, which is a digital image formed by a matrix of dots.

EPS

Encapsulated PostScript (EPS) file formats are used in professional printing. This format is used in vector-based images including Adobe Photoshop, Adobe Illustrator and CorelDRAW. Additionally, this file is also compatible with PostScript printers which are used for transferring files between several graphic applications.

GIF

A GIF stands for Graphics Interchange Format, which is mainly used in web graphics. This format is used widely after JPEG. This image format uses lossless compression, which means it doesn't noticeably degrade the original image.

JPEG

JPEG stands for Joint Photographic Experts Group. This format used in digital cameras to store photos because it supports 224 or 16,777,216 colors.

Moreover, it uses lossy compression. This format may reduce the size of the bitmap (BMP) file format without any degradation in quality.

PNG

PNG stands for Portable Network Graphics. This file format is used for application graphics and also widely used on the Web.

This format supports an alpha channel and 'RGBA' color space. There are three standard color channels (red, green and blue) with 256 levels of transparency.

Some other common file formats are PDF, PSD, TIFF, RAW and many more.

Final Word

There can be chances when we may run out of the storage space from our operating system. So of the most efficient ways is to compress the file or folder to save our system's disk space.

By compressing a file, data uses less space, and we can easily share the files more quickly.

Dividing large files into small fragments was very common in analog modems, as downloading a single 1GB file or more could take days or weeks. Instead, following the philosophy of 'divide et impera', downloading single fragments of the 100MB file allowed to interrupt the download after a certain number of fragments and continue at another time, without having to start over again. With the arrival of ADSL and above all of the optical fiber we can download dozens of GB in a short time, making this practice almost fall into disuse. It can happen again to come across a file divided into many fragments, often in RAR format: in these scenarios, we place this guide, in which we will show you how to merge RAR and ZIP files (or even other types of archives) so you can get the original file and extract its contents

How to merge RAR and ZIP files on Windows and Mac

The most likely scenario where we will find ourselves with numerous archives to merge is definitely the computer. In this part of the guide, we will show you the best free programs that we can use to be able to combine RAR or ZIP files. The only recommendation before using all the programs: we position the files to be merged into a single folder, so as not to run into errors during the extraction.

7-Zip

The best free program to combine RAR and ZIP files is definitely 7-Zip.

To merge compressed archives and extract their contents, open the program, take us to the path or folder where the files to be merged are saved, select the first RAR file in the series and click on the button Extract; in the next window, we choose a path to extract the content. In a few minutes, the files will be gathered automatically during the extraction, so as to be able to access the previously divided content. Compatibility with split RAR files is very good, as is extraction speed.

PeaZip

Another very useful free program to join RAR and ZIP files is PeaZip. How do i transfer vhs tapes to my mac.

To merge and extract the contents of the RAR or ZIP files, we navigate inside the interface up to the folder where the archive files are to be merged, select the first file in the series and click on top of Extract. In the window that appears we will only have to select the path in which to extract the contents of the divided compressed files.
Compatibility is also very good in this case, with a lower extraction speed than 7-Zip (but on powerful computers you don't even notice).

Bandizip

Another free program that we can use to join RAR and ZIP files is Bandizip.

Once the program is open, click on Open archive, select the first archive in the series and select the path where to save the content divided among the various compressed files. The program is currently one of the fastest we can use to join RAR and ZIP files, but it could present some problems with too many fragments (over 20).

B1 Free Archiver

One of the best for compatibility and decompression speed is B1 Free Archiver, available for free.

With this program we will only have to display the folder in which we have kept the files to be merged, select the first file in the series and press the button first You open then Extract. Similar to the other programs, we will now have to choose the path where to save the contents of the compressed archives.
As mentioned in the introduction, this program is one of the best when it comes to compatibility with split RAR files and one of the best for decompression speeds.

WinRAR

However, if we want to get the maximum compatibility and speed of extraction, we can install WinRAR on our computer, that is the program with which it is possible to create this type divided files.

Once the program is open, we browse through the folders on our computer to find the one where we have gathered all the files to be divided, click on the first file and then on Extract in. The program will make us choose where to save the content: we choose a folder of our choice or create a new one that acts as a container for the extracted files.
Currently, there is no program with greater compatibility and speed in joining the RAR files (and God forbid!), But WinRAR is provided for free only for 30 days, after which a paid license is required. In truth, the program continues to work even after the deadline, we will only have to go through the initial screen where we will be reminded to pay the license.

How to merge RAR or ZIP files on Android and iPhone

After seeing the programs for Windows and Mac, in this part of the guide, we will show you the apps to be able to reduce the RAR files, in case we happen to have them in our hands while using the smartphone. Just like on PC, we advise you to place the various files to be merged into a single folder of internal memory or microSD (if present), so as to be able to proceed quickly to merge and then extract.

The best apps we can try on Android smartphone or tablet I'm:

1. Solid Explorer: one of the best file managers available on the green robot, with full support for compressed archives, even those divided into several volumes.
2. RAR: the official app with which to extract the contents of all RAR compressed files, even those divided into many volumes. Currently the fastest and most practical with RAR files on Android.
3. Unrar: a file manager designed to quickly unpack all types of RAR archives saved in the internal memory or in microSD.
4. Simple Unrar: another simple app with which to combine and extract all the RAR files downloaded from the Internet or exchanged via social or chat.

On iPhone and iPad we can use one of the following apps to join ZIP and RAR files:

1. iZip – Zip Unzip Unrar Tool: a valid app for unpacking and for bringing together RAR files but also other types of compressed archives (such as ZIP files).
2. File Manager & Browser: a complete file manager for iOS with which to join RAR files and unpack them in a folder of your choice of system.
