Zip(String,String,EncryptionMethod,CompressionMethod,Boolean,Boolean,Boolean,String[]) Method


Xceed.Zip Assembly > Xceed.Zip Namespace > QuickZip Class > Zip Method : Zip(String,String,EncryptionMethod,CompressionMethod,Boolean,Boolean,Boolean,String[]) Method
The fully-qualified path and name of the zip file.
The password that will be used to encrypt the files.
The EncryptionMethod used to encrypt the files. If EncryptionMethod.WinZipAes is passed, an encryption strength of 256 will be used.
The CompressionMethod used to compress the file.
Boolean value indicating if existing files should be overwritten.
Boolean value indicating if files contained within sub-folders should be added to the zip file.
Boolean value indicating if the directory structure should be preserved in the zip file.
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).
Adds files to a zip file using an encryption password and specifying an encryption mehtod, whether existing files will be overwritten and if the directory structure will be preserved.

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).
Remarks

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.

Requirements

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
