AES encrypted ZIP files created with DIZipWriter can be opened and extracted with WinZip just like regular ZIP files with no or standard encryption.
- The new
TDIZipWriter.DataType
property allows to determine the data type attribute for each ZIP entry. The options aredtBinary
,dtText
, ordtUnknown
. For the latter,TDIZipWriter
determines the data type automatically. This new property was explicitly requested by some users who found that certain ZIP software apparently unzips differently depending on the data type. - Updated the deflate compression engine.
DIZipWriter v1.30 – 1. September 2003
- Improved Exception Handling for running out of disk space.
- Shortened the following methods of
TDIZipWriter

DIZipWriter v1.25 – 6. January 2003
- Both
NewZipFile
andNewZipStream
have anOffSet
parameter which specifies the final position of the Zip archive within the output file or stream. WhileOffset
is usually zero, it might differ when appending a Zip archive to a SFX stub in order to create self extracting Zip archvies. There are SFX stubs freely available on the Internet. - Improved error handling in case of stream write errors, like when running out of disk space.
- Established compiler compatibility with other Delphi Inpiration products.
DIZipWriter v1.20 – 11. November 2002
