ZipForge is a fast and powerful VCL Zip component, written in Delphi. It lets you easily create ZIP archives, extract files from zip files to hard drive or memory, add files to a zip archive from disk or memory, replace, move and delete files in zip archives. Also it creates and reads self-extracting (SFX) zip archives, AES encrypted and multi-volume zip files.

ZipForge main features:

Opens and creates archives encrypted with strong AES encryption algorithm
Zip64 supports - lets you create ZIP files over 4 GB
Unicode file names support
Includes transaction system which allows you to rollback changes if archive update failed
Adds compressed data directly from streams and extracts archived files to streams without creating temp files
Lets you store full path with drive for each file
Allows to search for files inside archive by mask
Progress indication
Full Delphi source code is available
