Python 2.7: Compressing data with the XZ format using the “lzma” module

由 一曲冷凌霜 提交于 2019-12-01 03:04:13
问题 I'm experimenting with the lzma module in Python 2.7.6 to see if I could create compressed files using the XZ format for a future project that will make use of it. My code used during the experiment was: import lzma as xz in_file = open('/home/ki2ne/Desktop/song.wav', 'rb') input_data = in_file.read() compressed_data = xz.compress(input_data) out_file = open('/home/ki2ne/Desktop/song.wav.xz', 'wb') in_file.close() out_file.close() and I noticed there were two different checksums (MD5 and

I'm trying to uncompress a .xz file which has a few foders and files inside. I don't see a direct way to do this using lzma module. This is what I'm seeing for a decompress method : In [1]: import lzma In [2]: f = lzma.decompress("test.tar.xz") --------------------------------------------------------------------------- error Traceback (most recent call last) <ipython-input-2-3b08bf488f9d> in <module>() ----> 1 f = lzma.decompress("test.tar.xz") error: unknown file format Are there any other methods to un-compress this file so that it will create the resultant folder ? Python 3.3 import tarfile

How to use LZMA SDK to compress/decompress in Java

http://www.7-zip.org/sdk.html This site provide a LZMA SDK for compress/decompress files, I would like to give it a shot but I am lost. Anyone got experience on this? Or a tutorial? Thanks. Short answer: don't The 7zip sdk is old and unmaintained and it's just a JNI wrapper around the C++ library. A pure Java implementation on a modern JVM (1.7+) is as fast as a C++ one and has less dependecies and portability issues. Have a look at http://tukaani.org/xz/java.html XZ is a file format based on LZMA2 (an improved version of LZMA) The guys that invented the XZ format build a pure java

Free compression library for C# which supports 7zip (LZMA) [closed]

I have a program (written in C#) that reads/writes its data directly (direct file access without server) to firebird database files. For a better exchange I want to (un)compress them on import/export for a better exchange over the internet without the need of an external program to (un)compress them. I know #ziplib which supports Zip, GZip, Tar and BZip2. What else free compression libraries for C# do you know? Is there a .NET library which supports LZMA so i can read/write ".7z" files? splattne There is a good article written by Peter Bromberg: 7Zip (LZMA) In-Memory Compression with C# Shows
