问题 I have tried adding a new folder to an existing 7za archive using the following command from command prompt: 7za.exe a repo.zip \res\pub\newfolder newfolder The above command added a folder to root of repo.zip. My intention was to add the new folder to location: \res\pub\folder inside repo.zip Can anyone suggest or give me a correct command to add folder to a specific path of an archive? Thanks, Pradeep 回答1: Try to create a source location folder which you use for an update of your

问题 This question already has an answer here : Python3: lzma unpack .7z file (1 answer) Closed 4 months ago . I was trying to decompress a 7z file using python, but I can't seem to figure it out. I figured I could use the lzma module in python 3, but I can't seem to figure it out: I thought it would work like the zipfile package: import lzma with lzma.open('data.7z') as f: f.extractall(r"<output path>") but after reading the documents, it doesn't seems to. So here is my question: How can you

问题 I have a RAR file and a ZIP file. Within these two there is a folder. Inside the folder there are several 7-zip (.7z) files. Inside every 7z there are multiple files with the same extension, but whose names vary. RAR or ZIP file |___folder |_____Multiple 7z |_____Multiple files with same extension and different name I want to extract just the ones I need from thousands of files... I need those files whose names include a certain substring. For example, if the name of a compressed file

How do I silently install a 7-zip self-extracting archive to a specific directory?

问题 The Ruby Devkit is a 7-zip based self-extracting archive. I would like to invoke it silently without having to install 7-Zip to extract the files to a folder of my choosing, so that I can script the installation. I imagine it to be something like: cmd> DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe /silent /dir="C:\DevKit" But that, of course, doesn't work. What command line flags must I use to silently extract this archive into a folder of my choice? 回答1: try this: C:\> DevKit-tdm-32-4.5.2

Powershell to Create a zip (or 7z) of each file in a folder then delete original file

问题 I have a folder with a Ton of iso images. I've found that a lot of the images have dummy data in them to reach the size of the original DVD. I can save an enormous amount of space by zipping them up. I tried creating a batch file but it failed to work properly. So, I basically want it to create a .7z for each file in a folder, then delete the original file. Here's what I got. It zips the files but it fails on removable of the files afterwards. Can't figure out why: function zipFiles() { dir *

问题 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)

How do I write binary data for 7z archive format?

问题 I've been pouring over the format description and source code for the 7z archive format, but I'm still having trouble writing a valid container. I assume I can create an empty container... anyway here's my start: std::ofstream ofs(archivename.c_str(), std::ios::binary|std::ios::trunc); Byte signature[6] = {'7', 'z', 0xBC, 0xAF, 0x27, 0x1C}; Byte major = 0; Byte minor = 3; ofs.write((const char*)signature, 6); ofs.write((const char*)major, 1); ofs.write((const char*)minor, 1); UInt64 offset =
