I've been trying to find out how to implement a ram drive in Vista. It
appears that your registry entries will do so.

I want to use the ram drive as a place to save files that I will only use in
the current session, like unzipping files. Can you tell me what entries I
would use to set up, say, a 512kb ram drive. Nothing fancy, just suitable
for saving files to.


Thanks to anyone who has suggestions or answers,
Danno

In my view, except for a very rare very special situation, it's
invariably a very bad thing to do. It reduces the amount of RAM
available to Windows, and can adversely affect your performance--in
many cases, very seriously.

There's no need to do that. If you are concerned about keeping those
temporary files, just create a folder on the hard drive to save them
in; then write a batch file to delete the contents of that folder, and
put a shortcut to that batch file in your Startup folder.

The above will accomplish the same thing without hurting your
performance.

But Ken, having a ram drive is so kewl!

You're probably right. Under 98 & 2000 I use to make a lot of use of batch
files. Just not used to thinking of them in Vista.

I'm going to use one as you suggest. Just for my edification, why does the
performance take such a hit? I've got 2MB ram and never go over 75% usage.


Thanks much for the help,
Danno

Most people don't have more RAM than they need, and if they use some
of it for a RAM drive, there is less RAM for Windows.

If you have more RAM than you can use, then, of course, a ram drive
doesn't hurt you. But that's very unusual.

You're welcome. Glad to help.
