.lzma File Extension

Developer: N/A
File type: LZMA Compressed File
You're here because you have a file that has a file extension ending in .lzma. Files with the file extension .lzma can only be launched by certain applications. It's possible that .lzma files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .lzma file?

An LZMA compressed file is stored in the LZMA format and is integrated with compression specifications implemented by the LZMA algorithm. Also known as the Lempel-Ziv-Markov chain algorithm, these LZMA compressed files are also implemented with encoding specifications and affixed with the .lzma extension to embed better compression ratios into these LZMA files compared to some file compression algorithms. Files and folders compressed in the LZMA format are reduced in size, promoting more efficient ways to distribute these files and folders through the Internet or via a wide variety of media types like CDs, DVDs and other external data storage devices, such as USB flash drives, memory cards and external hard disks. Quicker decompression is also implemented into the LZMA format. Required by certain LZMA files is the integration of the LZMA SDK (Software Development Kit) for computers running on Microsoft Windows-based systems. In Mac platforms, some LZMA files are encoded with particular standards that require the implementation of the LZMA Utils application into these Mac systems. These LZMA compressed files are affixed with the .lzma extension.

how to open a .lzma file?

Launch a .lzma file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .lzma file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .lzma files aren't yet associated with it. In this case, when you try to open a .lzma file, you can tell Windows which application is the correct one for that file. From then on, opening a  .lzma file will open the correct application.

a word of warning

Be careful not to rename the extension on .lzma files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .lzma. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
