Zip
Previous  Top  Next

The Zip preferences page is accessed by selecting Options, followed by Preferences and finally Archive from the main menu bar. Then click on the Zip tab at the top of the preferences dialog.

Internal UnZip

If you have already installed an archive manager and wish to continue using it set this option to Use registry association.

Compression level

This is tradeoff between speed and size. If you set the compression level to none or a low value the zip operation will be faster, but the archive size bigger. The scale goes from 0 to 9, where 6 is the default value.

Misc

Always install when double clicking Install.exe or Setup.exe

Today many applications are distributed in a Zip archive. The install feature makes it easy to setup such programs on your system by automatically extracting the archive to a temporary folder and starting the installer.

Default compression method

Magellan Explorer supports several Zip compression algorithms. The default algorithm to use can be configured on this page, but you can always change to a different algorithm in the New Archive dialog available from the archive menu.

·Deflate - Deflate is the compression algorithm used by the PKZIP 2.04g file format. This algorithm has pretty good compression and is quite fast. It is the default compression algorithm used by Magellan Explorer.  

·Deflate64 - The Deflate64™, also know as Enhanced Deflate, compression algorithm is a variation of the Deflate algorithm that uses a 64K sliding window rather than a 32K window in order to compress a sequence of bits. Deflate64™ takes longer to compress data than Deflate, however it provides better compression. In comparison to BWT, Deflate64™ is slightly faster but does not compress as well.  

·Burrows Wheeler - The BWT compression method is an implementation of the Burrows-Wheeler Transform compression algorithm with Huffman encoding. It was popularized by the UNIX and Linux BZip2 program. It offers significantly better compression than Deflate but takes longer to compress and decompress data.  

·Store - Uses no compression.  

Note: The Deflate64™ and Burrows Wheeler (BWT) algorithms create archives that may not be supported by all compression programs.
