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.
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.
