How does the LZMA compression method work?

Question

I need to know details about LZMA compression algorithm. I know its general concept, but I need some examples explaining it in detail. Can anybody please help me to get more information?

Thank you.

Thanks BenV, actually I know its general concept, I need more details and some examples about that. Thanks. – Charlinecharlock

rewrite the question, state what you know (possibly frow where) and ask the question about details. – Cartilaginous

I believe what Shadi is looking for is something like this: cs.duke.edu/csed/curious/compression/lzw.html . But for LZMA. – Racecourse

Answer 1

Try the LZMA SDK. It "provides the documentation, samples, header files, libraries, and tools you need to develop applications that use LZMA compression."

Can you tell us how to use this SDK – Cherenkov

@Frankenstein Download the SDK, look at the documentation and samples, try it out, and then if you have specific questions come back and ask them on StackOverflow. – Rutharuthann

You'll have a lot better luck posting a new question rather than commenting on an existing one. – Rutharuthann

Have you tried the examples from here?

2. http://lloyd.github.io/easylzma/

The first link show code that I tried and works. Not sure about the second one but it looks good.
