11. By using this option you may save yourself time when archiving files that are backed up repeatedly This option differs from the behavior of the freshen option in that files which are not already present in the ZIP file will be added To compress only updated files or files not already archived in a specific ZIP file use the update sub option with the add option as shown below pkzipc add update test zip doc 46 In this example a ZIP file called test zip is created in the current directory All files in the current directory matching the file specification doc will be added or updated into the test zip archive Compressing Only Files That Have Changed add freshen The freshen value allows you to selectively update files archived in a ZIP file PKZIP will compress only files that exist in the ZIP file and that have changed To update files that have changed use the freshen value with the add option as shown below pkzipc add freshen test zip You can also abbreviate the value so you could type the following instead pkzipc add fre test zip When you use freshen with add only files that already exist in the ZIP file and that have also changed will be compressed No new files will be added to the ZIP file If you only want to re compress specific files simply include those files in your command For example if you wanted to re compress a file called resume doc you would type something like this pkzipc

17. Compressing Files to Diskette span With PKZIP you can save your ZIP file or self extracting file to one or more diskettes when you create it instead of saving it on your hard disk drive You can also create a split archive that is saved as multiple files on your hard disk You can also have PKZIP format or wipe your removable media before writing to it Creating a Spanned Archive Windows On Windows you can save a ZIP file to multiple diskettes if it is too large to fit on a single one This is called disk spanning PKZIP prompts you to insert diskettes or other media as they are needed Depending on the size of the ZIP file it may be necessary for PKZIP to save the file on multiple diskettes This process is called spanning To create a spanned archive 1 Insert a diskette or other appropriate medium into its drive 2 Type your PKZIP command and press ENTER Make sure to specify the drive letter or path that corresponds to your destination drive A sample command line appears below pkzipc add span a test zip doc Note Ordinarily PKZIP recognizes removable media as such and spans them as necessary automatically even if you do not specify the span option However if PKZIP is unable to detect that you are creating your ZIP file on removable media use the span option to tell PKZIP to span 85 Creating a Split Archive The span option is also used to create a split archive A split archive is an archiv
18. SecureZIP allows you to digitally sign either individual files in an archive or the central directory of the archive itself or both Signing the central directory enables a 86 recipient of the archive to authenticate that the archive as a whole has not changed Both PKZIP and SecureZIP authenticate digital signatures on extraction SecureZIP signing functionality is based on the X 509 certificate standard to be compatible with standard authenticity functionality in other applications such as Microsoft s Internet Explorer SecureZIP currently supports Level or Class One certificates otherwise known as email or personal certificates These certificates must be in 1024 bit minimum RSA format and must contain a private key Before you can use SecureZIP to sign files you must have a digital certificate Digital certificates are available from a variety of certificate authorities Visit our web site for information on obtaining a certificate http www pkware com Options for Working with Signatures certificate Use the certificate option to specify a certificate to use to sign files To specify a certificate use one of the sub options described in the following table Note The certificate hash and sign options described below and the ability to use certificates to attach digital signatures are available only with SecureZIP 87 Sub Option For example lt Common Specify in quotes the common
