'af' - FAST ADD FILES TO ARCHIVE(S) [REGISTERED VERSION ONLY] The fast add command is almost identical to the add command in that it adds one or more files to one or more archives. The only difference is that the fast add command does not check the existing archive (if it does already exist) for duplicate files. Therefore, if one is not careful, one can add the same file to the archive multiple times. For example: lzx af test.lzx testfile lzx af test.lzx testfile The above case is allowed, and will result in two "testfile" files being in the archive. The add ('a') command, on the other hand, will not allow a file to be added twice. The fast add command is useful if you know that there will be no duplicate files in the archive. This command would typically be used in a FidoNet mail setup, where new mail packets are added to existing mail archives and the mail packets are all guaranteed to have unique names. In this situation, the fast add command can speed up mail processing dramatically.
