This article introduces a Java utility class named CompressUtil that provides methods for compressing files and directories into ZIP archives, handling duplicate filenames, creating new files safely, and offering HTTP endpoints for downloading the generated ZIP files in a single request.
This article explains how to build a Spring‑based download library that uses annotations to simplify downloading files, HTTP resources, or custom objects, supports both WebMvc and WebFlux, handles concurrency, compression, and event‑driven logging, and provides a modular architecture for extensibility.
This tutorial demonstrates how to install PySimpleGUI, use its one‑shot and persistent window patterns, employ a range of popup functions for messages, text, input, file/folder selection, and progress bars, and combine them to build a lightweight Python compression utility.
This article introduces a Java library that simplifies file and resource download handling in Spring MVC and WebFlux by using annotations, reactive programming, customizable handlers, source factories, concurrent loading, compression, response writing, and event‑driven logging to support a wide range of download scenarios.
This article introduces a Java library that simplifies downloading various resources—files, HTTP URLs, or custom objects—by using a single @Download annotation, reactive programming, customizable handlers, source factories, concurrent loading, compression, and event‑driven logging to streamline complex download workflows in Spring MVC and WebFlux applications.
This article explains how a Java download library uses a @Download annotation, reactive programming, handler chains, source abstractions, compression, and event logging to simplify downloading various resources—including files, HTTP URLs, and custom objects—while supporting both Spring MVC and WebFlux with concurrent processing and customizable pipelines.
This article explains how to use PHP's RarArchive and ZipArchive classes to extract RAR and ZIP files, create ZIP archives, and compress folders into RAR archives, providing step‑by‑step code examples and detailed explanations for each operation.
This article reviews the open‑source 7‑Zip utility, covering its recent updates, cross‑platform support, key features such as high compression ratios and AES‑256 encryption, and provides step‑by‑step installation and command‑line usage instructions for Windows, macOS, and Linux.
This article explains how to work with common compressed file formats such as zip, tar.gz, rar, and 7z in Python, detailing the relevant modules, usage patterns, and providing complete code examples for creating and extracting archives on both Windows and Linux.
The zip_entry_compressedsize() function in PHP returns the compressed size of a specific ZIP archive entry, taking a zip_entry resource obtained from zip_read() as its parameter and providing the size as an integer value.
This tutorial demonstrates how to install PySimpleGUI, design one‑shot and persistent windows, use various popup functions for messages, text input, file and folder selection, progress meters, and finally combine these features to build a lightweight Python zip‑compression tool with full code examples.
This article demonstrates how to improve Java file compression performance by replacing unbuffered FileInputStream with BufferedInputStream, then leveraging NIO Channels, transferTo, memory‑mapped files, and Pipe, showing step‑by‑step code examples and timing results that reduce processing time from 30 seconds to about 1 second.
This article explains how to improve the performance of Java code that compresses multiple images into a zip archive by replacing unbuffered streams with buffered I/O, then using NIO channels, direct buffers, memory‑mapped files, and pipes, achieving a reduction from 30 seconds to about 1 second.
This article demonstrates how to dramatically reduce the time required to compress multiple large images in Java by progressively applying buffered streams, NIO channels, direct buffers, memory‑mapped files and pipe techniques, measuring each optimization and explaining the underlying I/O mechanisms.
The article explains Alibaba Youku’s picture‑book team’s streaming ZIP decompression technique that bypasses the end‑of‑file central directory by using each entry’s local file header, supports PKWARE and AES‑encrypted archives, and achieves up to 100 % faster extraction, reducing a 30 MB file’s load time to under one second.
This concise tutorial shows how to use Python's built‑in zipfile module to recursively collect all files from a specified folder and create a compressed ZIP archive, including example code and a brief note on where to find more automation resources.
