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, 2007 and 2009
- Supports BCB 4, 5, 6, 2006, 2007 and 2009

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.
