There are two ways to have PKZIP add files from multiple folders in a single operation:In the Add Files dialog, build a list of files selected from different folders. You select files to add to a list in the same way that you select files to add to an archive; but, when you add files from a list, PKZIP waits until the list is complete and then adds all the files in one operation. See the help topic: Add Files from a List.Turn off Auto-Save and add files with drag and drop. The Auto-Save feature will save an archive automatically anytime you change the archives contents by adding or deleting files. When the feature is turned on (as it is by default), you do not need to manually save an archive each time after you change it. If you want to make several changes to an archive for example, add several different sets of selected files you can turn off Auto-Save so that PKZIP runs in delay-save mode. To turn off Auto-Save, right-click an empty area in the middle of the PKZIP main window and uncheck Auto-Save in the context menu. When Auto-Save is turned off, PKZIP creates an internal list of any changes you specify, but does not make the changes until you manually save the archive (or turn Auto-Save back on). Until then, PKZIP highlights names of files that you add, update, or delete in boldface and flags the files with special icons. When you save the archive, all of your changes are made in one operation.
