What is a .LZW file extension?
.LZW file extension has been classified as Archive and compressed Files.
.LZW is LZW compressed archive
The lzw file extension is used for archives compressed with the LZW compression method.
The compression format LZW is Lempel-Ziv-Welch or LZW compression.
Basically LZW creates tables of strings while compressing/decompressing data, and then later outputs the ID of the string rather than the string itself saving space. Decompression reads this and it to build a table of strings as it reads, saving the compression from needing to write large string tables at the beginning of the file, thus making it very effective.
.LZW file format is deprecated and this file format is no longer supported.
Currently, .LZW file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.
