How you finding the 7000 build of windows 7? good ible, i suggest a short list of uses for this. Maybe, you could work on a full sized ible about all the features of disk utility.

Well for windows 7 I went onto the windows 7 beta site and downlaoded it and i think i will work on a large list of uses for DMG files

I meant how are you finding it in terms of how is it, and what do you think to it?

wow thats much better than what i thought you said

Aww, man! I was going to comment on the Win 7 in the left hand side of the first screenshot. I have Win 7 and am running it on an 80 GB HDD. Since I skipped Vista (XP ftw!) Win 7 is amazing to me.

I also skipped Vista and went from XP to win7

I still don't feel comfortable with the fact that I need to specify a fixed file size from the start. Isn´t there a way to auto-resize the DMG like when compressing a ZIP or RAR?

yeah that seems to be the problem alot but you can make bigger than what you need.

sure, but what if I need a small file to distribute on the web? Does all of this files you download are carefully measured to make a .DMG according to the files it contain?. Maybe there's an application to create them with the smallest possible size, I'll take a look around...

FOUND IT!

In Disk Utility:

File/New/Disk Image From folder...

or command+shift+N

Take a look at this to add some fancy features to your image file like a background and to hide some things.
