Removing items from a zip file

This topic demonstrates how to remove items from a folder by retrieving a reference to a file within a zip file.

Basic steps

To remove an item from a zip file, the following steps must be performed:

Retrieve a reference to a file contained within the zip file using the ZippedFile class.
Once we have a reference to a file we verify the Exists property to make sure that the file actually exists.
Call the Delete method to delete the file.

This example demonstrates how to remove a file from within a zip file.

VB.NET Copy Code

VB.NET	Copy Code
`Imports Xceed.Zip Imports Xceed.FileSystem` `Dim f As New ZippedFile( New DiskFile( "c:\test.zip" ), "file.txt" )` `If f.Exists Then f.Delete() End If`

Imports Xceed.Zip Imports Xceed.FileSystem

Dim f As New ZippedFile( New DiskFile( "c:\test.zip" ), "file.txt" )

If f.Exists Then f.Delete() End If

C# Copy Code

C#	Copy Code
`using Xceed.Zip; using Xceed.FileSystem;` `ZippedFile f = new ZippedFile( new DiskFile( @"c:\test.zip" ), "file.txt" );` `if( f.Exists ) { f.Delete(); }`

using Xceed.Zip; using Xceed.FileSystem;

ZippedFile f = new ZippedFile( new DiskFile( @"c:\test.zip" ), "file.txt" );

if( f.Exists ) { f.Delete(); }

The main questions you should ask yourself when removing items from a zip file are:

Do you want to filter (specify specific files and folders) the items that are to be deleted? Use filters.
Do you want to display the status of the operation? See the Events topic.
Do you want to remove a specific folder? Create an instance of a ZippedFolder object rather than a ZippedFile object
Do you already have a reference on a folder? Use the GetFolder or GetFile method to retrieve a reference on the file or folder to remove.
Do you only want to do basic zip file operations? Use the QuickZip class.
