~~Title: TAR BZip2 Options ~~ When using the **[[.|Add to Archive]]** dialog to add files to a **.tbz2** archive, the following options are available: * **Compression level**: This lets you set the compression level used when adding the files to the archive. There are five compression levels available, ranging from //Fastest// (the quickest, but poorest compression level) to //Best// (which produces the highest level of compression but takes longer to archive). * **Use multiple threads**: If this option is on then Opus will use multiple threads when adding to the archive - on a multi-CPU machine this should make the compression process quicker.
