What is an LZW file

LZW files mostly belong to 7-Zip. LZW files are files that hold data compressed using the Lempel-Ziv-Welch algorithm.

Purpose: To shrink file size by using lossless data compression.

Usage: They may contain image data, XML content, or other file types. In some cases the file is a simple LZW compressed file, while other times it uses a GZIP internal format to handle compressed XML.

Functionality: This format makes it possible to store data in a compact form without quality loss and can be opened using tools such as 7-Zip or ncompress.

How do you open LZW files?

You need a suitable software like 7-Zip to open an LZW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your LZW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LZW file directly in the browser:. Just drag the file onto this browser window and drop it.
