Hi, I'm a newish Mac user and still getting a little confused about things. Besides not fully understanding exactly what a .dmg file is, I'm confused about how to install an application from one. So, I download an FTP manager and it plops onto my desktop as a .dmg file. When I double click, then the application appears in the Finder, at which time I click the executable and the application runs. What I don't get is how I actually install it. It doesn't seem like it's installed, since everytime I run it, I have to re-activate the .dmg. These are probably really dumb questions, and I'm not even sure if I'm using the right terms, but any tips would really help me out. Thanks.
