Putting WordPress in WAMP to build multiple sites

Hi, I am very new to WordPress. I saw a tutorial for installing WordPress on my local computer by copying the files straight to the www file in WAMP. The problem is, I want to be able to build multiple sites. I tried putting WordPress in www in its own file, but then it didn’t work.

I know I’m probably doing it wrong. I want each site to have its own file in www, both to keep each site from interfering with the others on the local computer, and to make moving the site online easier. Some other topics in here point to a help file about installing on MAMP, but I’m using WAMP, which is for Windows (MAMP is for mac). Mebbe I’m being dumb or dense, but I can’t figure it out. Can someone please help?

Thanks in advance,

Steve
