LZMA: What is LZMA Compression?


When perusing through your files, you have probably come across a file with the .lzma suffix. You may have also wondered what the file was and how a .lzma file works. These, on the surface, appear to be files that are encrypted or encoded in some way. Upon opening them with WinZip, you will probably see gibberish and random characters.

LZMA is an algorithm used for file compression. This can be anything from individual files and folders to archives containing multiple files/folders. This blog post will discuss what LZMA compression is and how you can do one.

What is LZMA compression?

LZMA compression is a type of data-compression algorithm. It was designed by Igor Pavlov as part of the 7z project and was first implemented in 1998. The name "LZMA" stands for "Lempel-Ziv Markov chain Algorithm".

LZMA compresses files using both statistical modeling and dictionary techniques. Statistical modeling allows for the analysis of entire blocks of text, whereas dictionary techniques compress small pieces simultaneously.

Like most algorithms of this sort, it works by replacing strings that frequently occur in the uncompressed data with pointers to previous occurrences.

In LZMA compression, frequency estimates can be calculated given a set of symbols or substrings. Once you have done this, you use the resulting estimates to find matches and replace them with pointers.

LZMA is designed to be extremely fast on a wide range of hardware, from traditional hard disks to modern solid-state drives and embedded devices with limited CPU power.

How to do LZMA compression

Using a program like WinZip, you can compress a file or multiple files into an LZMA format to save your hard disk. Here is a step by step guide on how to go about it:

Step 1: Download WinZip from the official WinZip website. If you already have installed it, check for updates and ensure it's compatible with your OS.

Step 2: Install WinZip on your computer and open the application. Enter your password or click "continue" if it is set up for first use. You should see a window appear with multiple options, such as "File," "Folder," etc. This window will display files (or folders) located in the same folder as where you executed the executable file.

Step 3: Choose the files or folders you want to compress using LZMA compression format from this list of files/folders on your desktop after opening WinZip. To move the files, drag and drop them into the area where the WinZip window previously appeared. A box with checkmarks and boxes next to your files pops up. These are your options, and you have the option of compressing all of them or just parts of them.

Step 4: After selecting which files/folders (or even the whole folder) you want compressed, click on "More Actions" in the bottom right-hand corner. This will bring up a drop-down menu that includes more options for compression such as "Archive," "Compress," etc. Select either one of them, depending on what type of LZMA compression format you would like to use.

Step 5: After you have selected the desired format, be sure to save your file, as there is no "undo" option for creating an archive with WinZip. Be sure also to uncheck all of the boxes that appear after you save the file. This helps reduce the size of the compressed file and may result in faster decompression rates.

As easy as that! You now know how to compress files using LZMA compression format efficiently on your computer with ease.

Get started with WinZip

The LZMA algorithm reduces the size of data without sacrificing its integrity. It's an excellent tool for reducing the size of large files, such as images or video content. With  WinZip, you can create and open. LZMA compressed files that are up to 10% smaller than ZIP compression while still maintaining fast decompression speeds.
