First, can you tell from what site you downloaded what? Then we know what you're talking about. I do know of other virtual CD programs like deamon tools, ISOdisk or VirtualCD, but never a Microsoft one.
To answer your questions:
- A browser should have a default location (folder) to store downloaded files, but most have the option to change that default to a place you like more. As you didn't tell what browser you use, that's all the help that I can give at the moment.
- Why do you think it's a zip-file? I've never seen a Microsoft utility come in a zip-file. Microsoft only uses msi (their own installer).
- What's your OS (Windows XP, Vista, 7)?
- When unzipping a file to be on the safe side always unzip to an empty folder (create one if necessary) as temporary storage unless you know exactly what files you're extract and where you want to put them.
- If you don't know how to copy a file in My Computer, go and start studying a basic book about Windows.
- If you don't know how to find a folder to copy to: same advice.
- As you didn't tell what instructions you're trying to follow I can't help with that.
Two general remarks:
- Why not buy an external drive? That's plug and play. No difficult installs.
- What are you going to use your virtual CD for?

So "newbie" that I lost my 'preview' of post! Have Acer Aspire One netbook without optical/cd/dvd drive, so located this utility, but am totally lost/confused and quite embarrassed. Searched further online instructions from various sites, but leaves me more confused. First, do not know whether to 'save' this or 'run' when downloading this utility. If I 'save' will likely not know where to locate it anyway. If I 'run', I do not know to which folder I should pick to extract folder before unzipping and closing. Do not know how to 'copy' the VCdRom.sys file, nor where the "C:/Windows/System32/Drivers" folder is to copy it to! Also, further along instructions are the"Add Drive' section as am unsure about 'changing' the letter (although, assume this file will not be preceded with a 'C'). Apologize for the extent of my ignorance and appreciate the assistance--basically, I guess I need someone to 'hold my hand' through the whole process, step by agonizing step right through to how to use this thing once I get this Vcd-rom installed! Thanks to anyone and all!
