Extracting from a gzip file

This topic demonstrates how to extract a file from a GZip archive to a destination folder. With Xceed’s FileSystem-based products, a file is a file: it does not matter if it is located on disk or in memory, etc.

FileSystem-based GZip is not currently available in Xceed's .NET Compact Framework products.

Basic steps

To extract items from a GZip archive, the following steps must be performed:

Retrieve a reference to a GZip archive using the GZipArchive class.
Retrieve a reference to a folder where the files will be extracted to using an AbstractFolder-derived class such as DiskFolder, MemoryFolder, IsolatedFolder, ZipArchive, FtpFolder, etc.
Call the CopyFilesTo method to copy the GZipped files to the destination folder.

Demonstration

This example demonstrates how to extract a GZipped file from a GZip archive to a folder located on disk.

VB.NET Copy Code

VB.NET	Copy Code
`Imports Xceed.GZip Imports Xceed.FileSystem` `Dim gzip As New GZipArchive( New DiskFile( "c:\test.gz" ) ) Dim folder As New DiskFolder( "c:\temp" )` `gzip.CopyFilesTo( folder, true, true )`

Imports Xceed.GZip Imports Xceed.FileSystem

Dim gzip As New GZipArchive( New DiskFile( "c:\test.gz" ) ) Dim folder As New DiskFolder( "c:\temp" )

gzip.CopyFilesTo( folder, true, true )

C# Copy Code

C#	Copy Code
`using Xceed.GZip; using Xceed.FileSystem;` `GZipArchive gzip = new GZipArchive( new DiskFile( @"c:\test.gz" ) ); DiskFolder folder = new DiskFolder( @"c:\temp" );` `gzip.CopyFilesTo( folder, true, true );`

using Xceed.GZip; using Xceed.FileSystem;

GZipArchive gzip = new GZipArchive( new DiskFile( @"c:\test.gz" ) ); DiskFolder folder = new DiskFolder( @"c:\temp" );

gzip.CopyFilesTo( folder, true, true );

Things you should consider

The main questions you should ask yourself when extracting items from a GZip archive are:

Do you want to display the status of the operation? See the Events topic.
Do you want to move items rather than copy them? Use the MoveTo method.
