7zip

I need to unzip/extract 7z compressed files in ios , Can anyone say the libraries used to do this,where are those libraries available to download.I there any sample project to do this ,let me know 7-Zip Lzma SDK - is a multi-language SDK for handling 7-zip files. Mo Dejong has created an example demonstrating how to use the LZMA SDK to decompress 7-zip libraries on iOS devices. You can find the example on his website here . iOS9 comes with LZMA support (encoder until level 6, decoder all levels). Of course this only helps if you just need the compression – if you absolutely need to read the 7z

I have installed 7-zip 4.65 on my machine at C:\Program files. I want to use it in C# code to zip a file. The file name will be provided by the user dynamically. Can any one please provide a sample code on how to use 7zip in C# code? lots of answer given above but i used this below mention code to zip or unzip a file using 7zip you must have 7zip application in your system . public void ExtractFile(string source, string destination) { // If the directory doesn't exist, create it. if (!Directory.Exists(destination)) Directory.CreateDirectory(destination); string zPath = @"C:\Program Files\7-Zip

I have a 7zip archive which contains some hundred files separated into different directories. The target is to download it from a FTP server and then extract it on the phone. My problem is that the 7zip SDK doesn't contain a lot. I am looking for examples, tutorials and snippets regarding the decompression of 7z files. (Decompression via Intent is only a secondary option) TienDC Go here : LZMA SDK just provides the encoder and decoder for encoding/decoding the raw data, but 7z archive is a complex format for storing multiple files. i found this page that provides an alternative that works like

I am creating an archive on Android using the code like this: OutputStream os = new FileOutputStream(zipFile); ZipOutputStream zos = new ZipOutputStream(new BufferedOutputStream(os)); try { zos.setLevel(8); byte[] buffer = new byte[32768]; for (VFile src : toPack) { ZipEntry entry = new ZipEntry(src.name); zos.putNextEntry(entry); src.pushToStream(zos, buffer); src.close(); zos.closeEntry(); } } finally { zos.close(); } I found that there's only one compression method available - DEFLATED (there's only STORED alternative available). This means that archive is always compressed with one method.

Currently, I am making a SFX with 7zip using the following config: ;!@Install@!UTF-8! InstallPath="C:\\test" GUIMode="2" RunProgram="7z465.exe" ;!@InstallEnd@! I then package 7z465.exe into Setup.7z, and then call the following line in a batch file: copy /b "C:\Program Files\7-Zip\7zSD.sfx" + config.txt + ".\Release\Setup.7z" .\Release\Setup.exe When I run the resulting Setup.exe, It extracts fine and launches the 7z465.exe as well, but it is still extracting to some 7zip temp folder for the current user and not C:\test! Running as administrator seems to have no effect either. Anyone have any

In the program I maintain it is done as in: # count the files in the archive length = 0 command = ur'"%s" l -slt "%s"' % (u'path/to/7z.exe', srcFile) ins, err = Popen(command, stdout=PIPE, stdin=PIPE, startupinfo=startupinfo).communicate() ins = StringIO.StringIO(ins) for line in ins: length += 1 ins.close() Is it really the only way ? I can't seem to find any other command but it seems a bit odd that I can't just ask for the number of files What about error checking ? Would it be enough to modify this to: proc = Popen(command, stdout=PIPE, stdin=PIPE, startupinfo=startupinfo) out = proc
