Using RAM as a 'virtual' HD Folder

[bravesfan258]

I recall reading an article a few years ago where someone created a 'virtual' folder in their laptop's ram, then copied an entire application to this folder, and launched it. This allowed them to work in this application without _ever_ accessing their machine's HD, which allowed them a few extra hours of battery time.

Anyone know how to do this? I have more RAM than battery in my machine now, and would love to take advantage of this.

PS - I understand that when you lauch a normal application, most of it is loaded to memory, but I still get HD spin when I run spell check, etc. The suggestion I read was to load _Everything_ associated with the application to RAM.

<edit - reply to responses - no need to bump this topic> Thanks for the responses below. I'll look up those utilities.

Grab a RAM drive program.

Do a search here in forums. It should be mentioned a few times over in the OS category.

You are talking about a RAM DISK or RAM DRIVE. That is an old DOS utility that would work using real mode drivers in DOS configuration files. But, when you do that, you remove that amount of RAM from Windows use. Why rely on battery time? Use the A/C adapter whenever possible. Most work places have power outlets.
