I make it for my Unattended MultiBoot CD with 6 versions of Windows XP SP2 + all post SP2 updates by RyanVM, more than 700Mb (uppacked) of drivers by Bāshrat the Sneaky, MUI pack, Symantec AV CE, FAR, WinRAR, 7z, Acrobat Reader, CCleaner, DaemonTools, FinePrint, pdfFactory, Sun Java 2 Runtime, K-Lite Mega Codec Pack, .NET Framework 1.1 SP1, TTF fonts, PartitionMagic, memtest86+, Drive Image, Easy Recovery and event working Windows 3.1 & Linux floppies… When you try to squeeze all of this to a single 700Mb CD, you’ll count every free byte, every free sector on CD. And because I consistently updating this CD - it's important for me to get as small as possible releases to squeeze them back to CD.
