7zip

问题 I have Several zip files that Contain multiple filetypes. The ONLY ones I am interested in are the .txt files. I need to extract the .txt files only and place them in a folder of their own, ignoring all other file types in the zips files. All the zip files are in the same folder. Example -foo.zip --1.aaa --2.bbb --3.ccc --4.txt -foo2.zip --5.aaa --6.bbb --7.ccc --8.txt I want to have 4.txt and 8.txt extracted to another folder. I can't for the life of my figure it out and spent ages looking,

问题 I'm writing a Python script where I need to call 7z to extract some files kept inside a directory in an archive without extracting the complete archive. The archive contains multiple directories and I need to extract some files from a particular directory. Let's say, "abc.7z" is an archive which contains multiple directories, i.e "temp", "windows", "system", "data". I want to extract some .exe files from directory "system" only because those .exe files might be present in other directories

问题 I am using Python 3.6, and currently I subprocess out to my 7zip program to get the compression I need. subprocess.call('7z a -t7z -ms=off {0} *'.format(filename)) I know the zipfile class has ‘ZIP_LZMA’ compression, but the application I am passing this too says the output file isn’t correct. So what else do I have to add to the ZipFile class to make it mimic the above command? 回答1: If you do not care much for Windows, then perhaps libarchive could help. In Ubuntu, for example: $ sudo apt

问题 I can use the DotNetZip library to unzip a single zip file: Using Zip As ZipFile = ZipFile.Read(ZipFilePath) AddMessage("Unzipping " & Zip.Entries.Count & " entries") End Using However, if I try and pass in the first segment of a split archive produced using 7-Zip (e.g. Pubs.zip.001) then it throws an error: Could not read block - no data! (position 0x03210FCE) The documentation seems to infer that you don't have to do anything special to read a split archive: This property has no effect when

问题 I need to run a script to compress all folders within a folder that is 2 levels within a directory structure. I want the script to compress all folders within the log folder and then delete the original folder, thus saving loads on space. To illustrate the folders I wish to compress, see below: Drive Location-->machinename-->logtype-->folders_i_want_to_compress Within folder 2 there are folders with dates in the format yyyymmdd and it is these that I wish to compress as zip files. I cannot

问题 If I'm running the 7z a -tzip myDestFile.zip some/dir command and I want to add to it a file extension whitelist, such that if I put *.txt *.xls *.doc, it will only add files with those extensions to the archive, how would I do that? The documentation does well at whitelisting by a single extension, but what about multiple? Am I just going to have to run the command several times in my script? I've tried the following: 7za a -tzip test.zip ./subdir *.txt *.xlsx # throws error 7za a -tzip test

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?
