7zip

I want to compress a folder into a file with the .7z extension, with 7zip. I would like to know how I would do this, because I'm not sure (which is why I'd asking.) This is in C#. Links to pages or sample code would be helpful. code to zip or unzip file using 7zip this code is used to zip a folder public void CreateZipFolder(string sourceName, string targetName) { // this code use for zip a folder sourceName = @"d:\Data Files"; // folder to be zip targetName = @"d:\Data Files.zip"; // zip name you can change ProcessStartInfo p = new ProcessStartInfo(); p.FileName = @"D:\7-Zip\7z.exe"; p

I'm doing a batch script so I can compress multiple directories inside a specific folder. The thing is it works perfectly if the folder is at C:\something, but if I try to do the same to a folder in i.e E:\something, I get an error. The script is this: @ECHO OFF if %1.==. ( SET "rootpath=%cd%" ) else ( SET "rootpath=%~1" ) FOR /D %%D IN ("%rootpath%\*") DO ( 7za a -t7z %%D.7z %%D\* -mx9 ) Example of how it works normally: C:\Users\Me\Desktop\ExampleFolder>script 7-Zip (A) 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18 Scanning Creating archive C:\Users\Me\Desktop\ExampleFolder\D1.7z

7z a -mx9 -sfx %1.exe %1 This is what i have so far as a batch file, which if i drag and drop a file or folder onto the batch file i get a 7zip SFX on Ultra Compression under the same name as the original file. but this only works if the file is in the same folder as the batch file. What im trying to achieve is, putting this batch file into the sendto folder so i can convert any file anywhere into a highly compressed exe, which appear in the folder of the original directory. Any help would be greatly appreciated, im sure its simple but i haven't a clue. Edit 29 May @ 16:50 [HKEY_CLASSES_ROOT*

I am using 7zip sdk (http://www.7-zip.org/sdk.html) to compress a file. it works fine using this wrapper: public void EncodeSingleFile(FileStream inStream, FileStream outStream) { bool eos = false; Int32 dictionary = 1 << 21; Int32 posStateBits = 2; Int32 litContextBits = 3; // for normal files // UInt32 litContextBits = 0; // for 32-bit data Int32 litPosBits = 0; // UInt32 litPosBits = 2; // for 32-bit data Int32 algorithm = 2; Int32 numFastBytes = 128; string mf = "bt4"; propIDs = new CoderPropID[] { CoderPropID.DictionarySize, CoderPropID.PosStateBits, CoderPropID.LitContextBits,

http://www.7-zip.org/sdk.html I can uses it compress a file, but can not find function of compress a Folder Arnaud Bouchez You'll have to create a .7z archive, then include all files of the folder within. There is no direct "folder" compression: just compression of files. If you store a (relative) folder name within the file name (e.g. 'FolderName\FileName'), the folder 'FolderName' will appear within the archive. You have within the SDK a ANSI-C compatible source code for 7z decompression with example. You'll have to adapt it to add all files of the folder to the archive (using FindFirst /
