问题 I have a file that has a Unicode name, say 'קובץ.txt' . I want to pack him, and I'm using python's zipfile. I can zip the files and open them later on with a problem except that file names are messed up when using windows 7 file explorer to view the files (7zip works great). According to the docs, this is a common problem, and there are instructions on how to deal with that: From ZipFile.write Note There is no official file name encoding for ZIP files. If you have unicode file names, you must

问题 I am using the latest version of ionic zip version 1.9.1.8.I have set the property of ionic zip ParallelDeflateThreshold = 0 .

问题 I have a Python script where I need to extract the contents of a ZIP file. However, the zip file is over 6GB in size. There is a lot of information about zlib and zipfile modules, however, I can't find a single approach that works in my case. I have the code: with zipfile.ZipFile(fname, "r") as z: try: log.info("Extracting %s " %fname) head, tail = os.path.split(fname) z.extractall(folder + "/" + tail) except zipfile.BadZipfile: log.error("Bad Zip file") except zipfile.LargeZipFile: log.error

问题 Is there a way to zip files using JavaScript?? For an example, like in Yahoo mail, when you chose to download all the attachments from an email, it gets zipped and downloaded in a single zip file. Is JavaScript capable of doing that? If so, please provide a coding example. I found this library called jszip to do the task but it has known and unresolved issues. How do I solve the problem? 回答1: JSZip has been updated over the years. Now you can find it on its GitHub repo It can be used together

问题 I use python's zipfile module to extract a .zip archive (Let's take this file at http://img.dafont.com/dl/?f=akvaleir for example.) f = zipfile.ZipFile('akvaleir.zip', 'r') for fileinfo in f.infolist(): print fileinfo.filename f.extract(fileinfo, '.') Its output: Akval�ir_Normal_v2007.ttf Akval�ir, La police - The Font - Fr - En.pdf Both files are unaccessable after extraction because there are invalid encoded characters in their filenames. The problem is zipfile module doesn't have an option

问题 I am trying to to extract files out of a nested zip archive and process them in memory. What this question is not about: How to read a zip file in Java: NO, the question is how to read a zip file within a zip file within a zip and so on and so forth (as in nested zip files). Write temporary results on disk: NO, I'm asking about doing it all in memory. I found many answers using the not-so-efficient technique of writing results temporarily to disk, but that's not what I want to do. Example:

问题 Need to handle if a zip file is corrupt, so it just pass this file and can go on to the next. In the code example underneath Im trying to catch the exception, so I can pass it. But my script is failing when the zipfile is corrupt*, and give me the "normal" traceback errors* istead of printing "my error", but is running ok if the zipfile is ok. This i a minimalistic example of the code I'm dealing with. path = "path to zipfile" from zipfile import ZipFile with ZipFile(path) as zf: try: print

问题 I'm setting up a function where I collect a list of apk files, then inside a For-loop, I declare a ZipFile intense to check the ABI Directories under the lib folder, by checking if any file ends with ".so". The only option I can solution I can think of is to use regex String expressions I've made several regex expression attempts with \b, [A-Za-z-0-9]*, but I keep getting NullPointerException. I researched solutions for using regex with File names, but not really cases for ZipFile and

问题 According to the zip file standard: http://www.pkware.com/documents/casestudies/APPNOTE.TXT it also supports splitting a zip file across multiple files: Spanned/Split archives created using PKZIP for Windows (V2.50 or greater), PKZIP Command Line (V2.50 or greater), or PKZIP Explorer will include a special spanning signature as the first 4 bytes of the first segment of the archive. This signature (0x08074b50) will be followed immediately by the local header signature for the first file in the
