Syntax

TsbxArchiveWriter

Remarks

Use ArchiveWriter to compress, update, and modify files in archives. ArchiveWriter archiveWriter = new ArchiveWriter(); archiveWriter.setEncryptionType(ArchiveWriter.aetGeneric); // the type of encryption to apply to the archive archiveWriter.setEncryptionPassword("MyPassword"); // specifies the archive encryption password // creates a new archive with the desired archive type as a parameter archiveWriter.createNew(ArchiveWriter.aftZip); // add a file to the archive, the first parameter specifies the path where the file will be saved within the // archive, the second parameter the file that you want to add to the archive archiveWriter.addFile("","C:\\Photos\\MyPhoto.jpeg"); // add a collection of files to the archive, first param specifies the desired mount point for the files within the archive, // second param is the path to the files on the local system, and the last one indicates whether you want to process the // subdirectories recursively archiveWriter.addFiles("","C:\\Photos",true); archiveWriter.save("C:\\MyArchives");

The following common archive formats are supported:

• ZIP (.zip)
• GZip (.gz)
• BZip2 (.bz2)
• Tar+GZip (.tar.gz)
• Tar+Bzip2 (.tar.bz2)

Working with ArchiveWriter

Work with ArchiveWriter builds on the following steps:

Creating or opening the archive.

Use CreateNew to create a new archive, or one of the Open* methods (such as Open or OpenBytes) to open an existing compressed file.

Inspecting the archive contents

Use the Files collection to access information about individual files stored in the opened archive. On this stage you can adjust the individual files objects' ACTION> and DATASOURCE> properties to configure bespoke processing for specific files.

Adding files to the archive

ArchiveWriter offers the following methods that you can use to add elements to the archive:

• AddFile - adds an entry with the contents of a local file.
• AddFiles - adds a set of files from a local directory.
• AddVirtual - allocates an entry in the archive. The actual data can be provided later using PrepareFile and BeforeCompressFile events.

You can combine different entry types when building your archive.

Updating files in the archive

You can update files already present in the archive (e.g. with newer copies) using UpdateFile and UpdateFiles methods. The Remove method lets you delete individual files from the archive.

Use DecryptionPassword property to specify a decryption password for an archive and/or a specific entry within it. If the password is required but wasn't set, or if the provided password is wrong, the component will fire the DecryptionPasswordNeeded event. This event is fired repeatedly until the correct password is provided or its Cancel parameter is returned as true.

Saving and closing the archive

Once you are finished with composing/editing the archive, call the component's Save (or SaveBytes) method to save the updated archive, and then Close to close the archive file and release the associated memory.
