Understanding iDAT Technology The entries in the Incremental Resolver table, meanwhile, translate the sequential numbers from the Multiple Patch Table into actual filenames that the AutoUpdate utility can download. The DELTA.INI file also has checksum and other information that the AutoUpdate utility can use to verify that files it downloaded have not changed or become corrupted. NOTE: If an iDAT download fails for any reason, the AutoUpdate utility will download and install a full .DAT update. After it downloads the correct .UPD file, the AutoUpdate utility decodes the existing .DAT files, patches the downloaded iDAT files into them, validates the data, then re-encodes the newly updated .DAT files for use with your software. NOTE: Because the iDAT files patch the existing .DAT files you may not download the iDAT files through the AutoUpdate utility and use the utility to save them for later updates. You can download the .UPD packages independently from the McAfee FTP site, however, and save these files for later distribution. See "Best practices" below for details. What does McAfee post each week? Each week McAfee posts a complete .DAT file update, along with a new weekly iDAT update, and a new DELTA.INI file that has updated Multiple Patch Table and Incremental Resolver entries. You can download these files independently of the AutoUpdate utility for posting on your internal servers from the McAfee FTP site at: ftp://ftp.nai.com/licensed/antivirus/datfiles/4.x/ Ë IMPORTANT: To connect to this site you must have a licensed customer user name and password. The FTP site will not accept anonymous connections. A typical file listing would be: 00_index.txt 40534054.UPD 40544055.UPD 40554056.UPD User's Guide 321
