Parameters

zipFileName

The fully-qualified path and name of the zip file.

encryptionPassword

The password that will be used to encrypt the files.

encryptionMethod

The EncryptionMethod used to encrypt the files. If EncryptionMethod.WinZipAes is passed, an encryption strength of 256 will be used.

compressionMethod

The CompressionMethod used to compress the file.

replaceExistingFiles

Boolean value indicating if existing files should be overwritten.

recursive

Boolean value indicating if files contained within sub-folders should be added to the zip file.

preservePaths

Boolean value indicating if the directory structure should be preserved in the zip file.

filesToZip

The files to add to zipFileName. Can contain filemasks and folder names (ending with a backslash). All subfolders will also be scanned for the specified file(s), even if wildcards are not used, if recursive is set to true. For example, if "C:\test.txt" is specified, all "test.txt" files found on the "C:\" drive will be added to the zip file. Folders specified with the backslash after them will include their entire contents. Cannot be a null reference (Nothing in Visual Basic).

The PPMd algorithm uses a custom memory management system called SubAllocator. In a zip file, the memory size the SubAllocator uses is defined in the WinZip PPMd header for the compressed file and this header's value is used when decompressing the data. In general, WinZip uses 64Mb. Since the algorithm used was not optimized from the original PPMd version I revision 1, the SubAllocator initially requires the total amount of memory specified in the PPMd compressor. This means you must have at least 64 free Mb of RAM when using this compression method.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
