Opus can add items to the context menu for files and folders that lets you access its archiving capabilities. This page lets you choose which items are added.
Use the Enable Archive context menu option at the top of the page to enable or disable the context menu support. The list of options below that is grouped into five sections:
The options in this section will add context menu items that invoke the Add to Archive dialog box for the selected files. The Add to Archive dialog lets you choose the archiving format to use, so you really only need one option from this section selected. The format you select here will be the default when the dialog box opens, so you can turn on multiple formats in order to have a quick way of invoking the dialog with the format already chosen.
The options in this section will add context menu items that immediately create archives in the specified format. The name of the new archive will be based on the first selected item. You won't have any way to control archiving options using these commands - the archives are created immediately.
These options add context menu commands that archive the selected files and send them automatically as an email (using the settings on the Email page).
These options add context menu commands that let you extract archive contents.
This section contains options that affect the archive context menus.
