7zip

I am trying to zip/7z folders using the command line of 7zG.exe. The code I have works for files but not folders. Could someone please show me the correct way using 7z command line to compress folders? Here is the sample code that works for files only. Whenever I try running this code 7zip shows a messagebox saying "Invalid Parameter" string sourceName = "Folder\Folder1"; string targetName = "Example.gz"; // 1 // Initialize process information. // ProcessStartInfo p = new ProcessStartInfo(); p.FileName = "7zG.exe"; // 2 // Use 7-zip // specify a=archive and -tgzip=gzip // and then target file

I have to frequently search through a couple of .7z (zipped with LZMA) files. I don't have enough memory to have them unpacked at the same time or to change the archive to .gz. At the moment I unpack one, search for what I need, delete what was extracted, unpack the next. I want to go through the archives in the same way as with gzip: f = gzip.open('archive.gz') for i in f: do stuff Is there a module/way to do this with .7z files? There is a built in module in Python >= 3.3: http://docs.python.org/3.3/library/lzma And there is also a backport of the module on the PyPI: https://pypi.python.org

I use 7zip to create the SFX as follows: 7z.exe a -r archive.7z * Then I do a binary copy with the 7zS.sfx file (used to create a self extracting installer), config file "build.config", and the archive. The contents of config file are as follows: ;!@Install@!UTF-8! RunProgram="setup.exe" GUIMode="1" Path="%tmp%\\mytemp" ;!@InstallEnd@! Binary copy command is as follows: copy /b 7zS.sfx + build.config + archive.7z sfxInstaller.exe Problem is that the result SFX "sfxInstaller.exe" requires admin privileges for executing. Is it possible to generate Self Extracting Archives using 7-Zip that do not

I am trying to write a batch script that will run automatically compressing subdirectories using winrar or 7-zip: Example: My Pictures Pics1 (Pics1.zip) File1.jpg File2.jpg File3.jpg Pics2 (Pics2.zip) File4.jpg File5.jpg Pics3 (Pics3.zip) File6.jpg File7.jpg ... How do i write script. (1) Using WinRAR: WinRAR includes two command-line tools, rar.exe and unrar.exe , where rar.exe compresses and unrar.exe uncompresses files. Both are located in the C:\Program Files\WinRAR folder in the installable version. Assuming, if there are multiple subfolders under C:\MyPictures and you want each subfolder

I'm trying to run a Powershell command to call 7-Zip to zip up a folder using the following command: $command = $SevenZip + " a " + $targetDirForZip + $GetDateName + "_" + $dir.Name + ".7z " + $dir.FullName Invoke-Expression $command The variables being fed into $command are already set and $SevenZip is "c:\Program Files\7-Zip\7z.exe" This isn't working and I'm trying to work out the best way to call 7-Zip from Powershell. Ideas? I've had the same problem before. This is code (almost) straight from a backup script that I use currently: [string]$pathToZipExe = "C:\Program Files\7-zip\7z.exe";

I'm thinking about using the 7-Zip format to pack my application files since it's a very compact and popular format. I can't find some tutorials on how to use the C++ SDK, though. I'd like some tutorials that teach me how to: Open an archive from memory (buffer) instead of directly from disk. Extract individual files inside the archive, to buffer, not to disk. Check if a certain file can be found in the archive. From the LMZA SDK documentation: ANSI-C LZMA Decoder ~~~~~~~~~~~~~~~~~~~ Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58. If you want to use old interfaces

Is it possible to do random access (a lot of seeks) to very huge file, compressed by 7zip? The original file is very huge (999gb xml) and I can't store it in unpacked format (i have no so much free space). So, if 7z format allows accessing to middle block without uncompressing all blocks before selected one, I can built an index of block beginning and corresponding original file offsets. Header of my 7z archive is 37 7A BC AF 27 1C 00 02 28 99 F1 9D 4A 46 D7 EA // 7z archive version 2;crc; n.hfr offset 00 00 00 00 44 00 00 00 00 00 00 00 F4 56 CF 92 // n.hdr offset; n.hdr size=44. crc 00 1E 1B
