Xceed Zip for ActiveX provides a robust, efficient ActiveX COM component designed to create, modify, and manage ZIP archive files. It supports modern compression standards, including encryption and multilingual filenames, and offers versatile features for managing zip files both on disk and entirely in-memory. This component handles multiple simultaneous operations, and supports multi-threading.

Compression and Encryption

Provides fast, low-memory compression supporting PKZip 2.04g, PKZip 4.5, Zip64, BZip2, Deflate64, and WinZip 12-compatible LZMA compression methods. Includes AES encryption for secure ZIP file creation and supports UTF-8 encoded filenames for international character support.

Zip File Manipulation

Enables creation and modification of standard, spanned, self-extracting, and multi-part ZIP files with no file count or size limits. Supports extraction to disk or memory, file-by-file filtering, renaming within archives without full extraction, and file attribute and timestamp management.

Event-Driven Operation and Feedback

Triggers multiple events throughout zip operations providing real-time updates, progress percentages, file-level status, and customizable file handling decisions.

Self-Extracting Zip File Creation

Supports creating and updating customizable self-extracting ZIP files with options for user prompts, license agreements, password requests, custom icons, and post-extraction commands.

In-Memory Streaming Compression

Includes a streaming compression library for compressing and decompressing strings or buffers entirely in memory with support for GZip, Zlib, and BZip2 formats, suitable for databases, web services, and continuous server operations.

Direct DLL API Access

Exports all properties, methods, and events via a single DLL with accessible API for integration in various programming models, including callback and Windows message event handling, across single, wide character, and Unicode string formats.
