Member	Description
High	Highest compression with the slowest speed.
Low	Lowest compression with the fastest speed.
Medium	Moderate compression with moderate speed.

For no compression, use CompressionMethod.Store.

The following example demonstrates using QuickZip and specifying specific options. Only QuickZip is required in this operation.

Visual Basic

' Be sure to import the namespace by putting "Imports Dart.PowerTCP.Zip"
' at the top of your class.

' Preserve the path structure of the files
Archive1.PreservePath = True
	
' Include any subdirectories
Archive1.IncludeSubs = True
	
' Specify compression level
Archive1.CompressionLevel = CompressionLevel.Medium

' Use the Deflate compression method
Archive1.DefaultCompressionMethod = CompressionMethod.Deflate

' Exclude any text files
Archive1.ExcludePattern = "*.txt"

' Set to use encryption
Archive1.DefaultEncryption = Encryption.Standard

' Specify the password
Archive1.Password = "testme"

' Perform the compression operation - this is the only required method for the operation
Archive1.QuickZip("c:\\Test\\*.*", "c:\\test.zip")

C#

// Be sure to import the namespace by putting "using Dart.PowerTCP.Zip;"

// Perform the compression operation - this is the only required method for the operation
archive1.QuickZip("c:\\Test\\*.*", "c:\\test.zip");
