two quick tips:

1) I had a cd with about 40 folders and a total of almost a thousand files on it. I wanted to move all that to a hard drive, but if you drag and drop the cd image (as mounted on the desktop) all you’ll get on the drive is an alias to the CD, not the actual files.

Solution a): go to the desktop and highlight your CD disc image. Press command c (as in “copy”.) Then move to where you want the disc and files copied and press command v (as in “paste”.)

Solution b): hold down the option key when you drag the image to the hard drive.

That’s tip one.

Here’s tip two:

2) Got a folder full of thousands of files you want deleted? Got a folder of folders of files (maybe thousands of them) you want deleted?  Fear not! it is not necessary to open each folder, select all, and drag everything to the trash… over.. and… over…and…over… again…

If you’ve got “folder A” with lots of things in it, and you all those things erased forever, just do this: somewhere else, make a folder named exactly “folder A” (that is another folder with the same name as the one whose contents you want gone.)

Then drag it to where the first “folder A” is. The finder will ask if you want to replace it with the new one. Just say yes.

You’ve just replaced the full folder with the empty one of the same name, and deleted all those pesky files in one fell-swoop.
