zipfile

I made a little helper function: import zipfile def main(archive_list=[],zfilename='default.zip'): print zfilename zout = zipfile.ZipFile(zfilename, "w") for fname in archive_list: print "writing: ", fname zout.write(fname) zout.close() if __name__ == '__main__': main() The problem is that all my files are NOT being COMPRESSED! The files are the same size and, effectively, just the extension is being change to ".zip" (from ".xls" in this case). I'm running python 2.5 on winXP sp2. This is because ZipFile requires you to specify the compression method. If you don't specify it, it assumes the

I'm having a hard time figuring out how to unzip a zip file with 2.4. extract() is not included in 2.4. I'm restricted to using 2.4.4 on my server. Can someone please provide a simple code example? You have to use namelist() and extract() . Sample considering directories import zipfile import os.path import os zfile = zipfile.ZipFile("test.zip") for name in zfile.namelist(): (dirname, filename) = os.path.split(name) print "Decompressing " + filename + " on " + dirname if not os.path.exists(dirname): os.makedirs(dirname) zfile.extract(name, dirname) There's some problem with Vinko's answer (at

I have a list of zip and rar files in a local folder. All I need to do is to extract the contents of the zip as well as rar files and to save them in a folder with the same name of the respective archive file. Since I am new to as3, I have no clue for this. Is there any Library for this??? Thanks in advance... There are a few libraries out there that deal with ZIP files in as3, but beware that this is no easy task for a beginner in ActionScript 3. FZip seems to be the most widely used, but it requires that the ZIP archives have Adler32 checksums . Provided with the library there is a Python

How can I add some file (almost always a single .csv file) to an existing zip file? Since you are in .NET 4.5, you can use the ZipArchive (System.IO.Compression) class to achieve this. Here is the MSDN documentation: ( MSDN ). Here is their example, it just writes text, but you could read in a .csv file and write it out to your new file. To just copy the file in, you would use CreateFileFromEntry , which is an extension method for ZipArchive . using (FileStream zipToOpen = new FileStream(@"c:\users\exampleuser\release.zip", FileMode.Open)) { using (ZipArchive archive = new ZipArchive(zipToOpen

I want to create a zip file. Add a folder to the zip file and then add a bunch of files to that folder. So I want to end up with a zip file with a single folder with files in. I dont know if its bad practice to have folders in zip files or something but google gives me nothing on the subject. I started out with this: def addFolderToZip(myZipFile,folder): folder = folder.encode('ascii') #convert path to ascii for ZipFile Method for file in glob.glob(folder+"/*"): if os.path.isfile(file): print file myZipFile.write(file, os.path.basename(file), zipfile.ZIP_DEFLATED) elif os.path.isdir(file):

I am fairly new to C# and coding in general so some of this might be going about things the wrong way. The program I wrote works and compresses the file as expected, but if the source is rather large, the program appears (to Windows) to hang. I feel like I should be using a Thread but I am not sure that will help. I would use a progress bar but the 'new' (.net 4.5) library for zipfile from System.IO.Compression which replaced Ionic.Zip.ZipFile does not have a method to report progress? Is there a way around this? Should I be using a Thread ? or DoWork ? The trouble is that the user and the
