问题 I've followed several articles to create a zip file using java ZipOutputStream class. The zip is created but I cannot open it. On my Mac I'm receiving this message when I open it with the unzip command : End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of

问题 Can someone helps me out with my problem. I have to take a file's directory in zip file so i can calculate its MD5 hash (without unzip it). I am using DotNetZip Library but i can't find the solution of the problem. I'll show you what i've tryed and hope you will help as fast as possible. Thanks! if (ofd.ShowDialog() == DialogResult.OK) { using (ZipFile zip = ZipFile.Read(ofd.FileName)) { foreach (ZipEntry f in zip) { GetMD5HashFromFile(ofd.FileName+"\\"+f.FileName); } } } 回答1: The problem is

问题 I am trying to download the dataset at the below link. It is about 14,000,000 rows long. I ran this code chunk, and I am stuck at unzip(). The code has been running for a really long time and my computer is hot. I tried a few different ways that don't use unzip, and then I get stuck at the read.csv/vroom/read_csv step. Any ideas? This is a public dataset so anyone can try. library(vroom) temp <- tempfile() download.file("https://files.consumerfinance.gov/hmda-historic-loan-data/hmda_2017

问题 I'm trying to write a collection of yara signatures that will tag zip files based on artifacts of their creation. I understand the EOCD has a magic number of 0x06054b50, and that it is located at the end of the archive structure. It has a variable length comment field, with a max length of 0xFFFF, so the EOCD could be up to 0xFFFF+ ~20 bytes. However, there could be data after the zip structure that could throw off the any offset dependent scanning. Is there any way to locate the record

问题 Is there any JS library that allows to provide input data in chunks rather than expecting 100% file content to be present in memory (string, Buffer, UInt8Array) before starting archivation? I checked several popular libraries like JSZip or archiver and found that they do not offer such functionality. We process large data tables, client side, using Javascript and we have feature to export table to CSV file, compress and upload to server. Currently we generate huge string which is passed to

问题 I am creating a Shiny application and I want to download my results in a zip archive. Before, it was working for me because I was using Rx34 bits. Unfortunately, it is not working since I have used Rx64bits. I found some example which isn’t working for me: library(shiny) ui <- shinyUI(fluidPage( titlePanel("Old Faithful Geyser Data"), sidebarLayout( sidebarPanel( downloadButton("downloadData", "Download") ), mainPanel( DT::dataTableOutput('myTable1') ) ) )) server <- shinyServer(function
