问题 I have folder in like CW1234.zip and it has various folders and subfolders like below. So, CW1234.zip has CW_All folder which in turn has CW123 and CW234 folders and so on CW1234.zip CW_All CW123 xyz.pdf CW234 abc.doc and to extract I use this code: from zipfile import ZipFile with ZipFile(r'CW41234.zip', 'r') as zipObj: # Extract all the contents of zip file in current directory zipObj.extract() The only problem is the unzipped folder I get is from CW_All and all the subfolders and file.

问题 I have byte[] zipFileAsByteArray This zip file has rootDir --| | --- Folder1 - first.txt | --- Folder2 - second.txt | --- PictureFolder - image.png What I need is to get two txt files and read them, without saving any files on disk. Just do it in memory. I tried something like this: ByteArrayInputStream bis = new ByteArrayInputStream(processZip); ZipInputStream zis = new ZipInputStream(bis); Also I will need to have separate method go get picture. Something like this: public byte[]image
