  • 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.
  • Up to 999 split or spanned archive parts
  • 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.
• Uses the latest version of ZLib 1.2.3 for compression and decompression
• Faster processing due to linking to Zlib 1.2.3 object files for compression and decompression routines.
• Supports Delphi 4, 5, 6, 7, 2005, 2006, and 2007
• Supports BCB 4, 5, 6, 2006, and 2007
• Even Delphi 4 and 5 and BCB 4 and 5 support Zip64 format
• Blocked Zip Files (spanned zip archives split onto hard drive)
  • Now completely 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.
• Event OnGetNextStream - Allows you to zip from multiple streams when using the ZipFromStream method. This improves performance since repeated calls to ZipFromStream causes the archive to be updated on each subsequent call.
• NOTE: VCLZip Pro does not support the Deflate64 compression.
• Price is $99.95 per developer for the first year of support. Annual renewals are only $79.95.
