The VCLZip Delphi component allows you to add ZIP and UNZIP capabilites to your application. This component is different from most other "ZIP" development libraries in that it is written in 100% Delphi Object Pascal code and is full featured. There are no DLL's to tote around. This component links right into your application's executable. It is very easy to use. Just SOME of the features include:
Create zip files fully compatable with PKZip Completely native Delphi VCL (NO DLLS) Create Disk Spanning and Blocked zip files Delphi 4, 5, 6, 7, 2005, 2006, 2007 and 2009 compatible C++ Builder 4, 5 6, 2007, and 2009 compatible Zip directly from streams to zip files Unzip directly to streams from zip files Stream to Stream zipping and unzipping Unzip directly to memory buffers Zip directoy from memory buffers Create and read Zip and File Comments Create Self Extracting Zip Files (16 bit and 32 bit distributable Windows sfx stubs included (source included for these too) or use your own stubs) Complete support for encrypted files (encrypts as it zips) Save Relative Path information Unzip using Relative Paths (even if zip file wasn't created with relative path info) Use enhanced wildcards Exclude List (tell VCLZip which files not to include (use wildcards too)) NoCompress (STORE) List (tell VCLZip which files to just store (use wildcards too) Set your own temp directory Plenty of events Long filenames, even the 16 bit VCLZip/VCLUnZip Includes comprehensive Zip Utility with source as demo Includes a small stream zipping demo Includes a context sensitive help file Use Unicode filenames, archive names, and pathnames (except for Delphi/BCB 4 and5) . No Royalties! AES Strong Encryption Zip64 capabilities, properties, methods and events: Uncompressed, Compressed, and Archive file sizes can be up to 2^63-1 bytes in length. You can compress up to 2147483647 files into an archive. This is compatible with PKZip's Zip64 format. If a file does not extend beyond any of the original limitations (filesizes of 4 gig or 65535 files) then no Zip64 format information is included in the archive. property isZip64 - tells you when you are working with a zip file that is using Zip64 format. Faster processing due to linking to Zlib 1.2.3 object files for compression and decompression routines. Blocked Zip Files (spanned zip archives split onto hard drive) Compatible with PKZip and WinZip split archives file naming format. For backwards compatability you can tell VCLZip to use the old VCLZip filenaming format by using the BlockMode property
