Q Help
Creating a new Disk Image
To create a new Hard Disk Image, please select "Create New Hard Disk Image..." from the "Tools" Menu.
- Select your desired hard disk size, in megabytes.
(Please see Create or edit an emulated PC for size recommendations)
- Select the format for the Disk Image.
- qcow
"Qcow" is a compressed disk image: when created, a qcow image is only a few kilobytes in size, but grows as required until it reaches the maximum size which you enter here. Please note that qcow images do not shrink when you delete data on them.
- raw
"Raw" is an uncompressed disk image: it can take a few minutes to create a raw disk image (also known as ".iso" or ".img"), and the disk image immediately takes up the entire amount of disk space that you enter here. However, raw disk images have an advantage that they can be mounted by the OS X Finder by double-clicking on them (you may have to change the file suffix to .img before OS X will recognize that it can be mounted).
- Select a name for the Disk Image.
Please select a location and enter a file name for your new Disk Image.
- Please wait...
"qcow" (compressed) images are created almost instantly. "raw" (uncompressed) images can take some time to be created (depending on their size).
