Compression

James,

Unfortunately, the compression on an image cannot be changed. The only way to do this is to create a new image. One thing I will point out, though is that Ghost has nine levels of compression (ten if you count no compression). Fast is level one, High is level two. Levels three through nine are only available through command line switches. If you want to do a higher level of compression whil taking the image, you can use the -z# switch, where # is the level of compression desired. Example: -z4

So, I apologize that editing an existing image is not possible, but this should allow you more options for compression.

Thank you,

Randy

Okey dokey no worries, i

Okey dokey no worries, i didnt think i would be able to do. But will i have to Compile every image when i've done or should i just make sure i dont put special characters or numbers in when i give the new image it's name.

So how exactly do i do this -Z# switch and where do i do it please?

Thanks
James

Naming and switches

James,

I would just create the images without special characters or numbers from the start; there is no need to recompile if you create them with a naming convention that does not use numbers. What I often recommend is making subfolders for images that contain machine model numbers, and saving images in these to identify them.

To address the -z# switch, you can either add this to boot media when creating it in the boot wizard, or you can add it to a Ghost Console task.

Boot wizard:
On the page that specifies the location of the Ghost.exe or Ghost32.exe executable, there is a line called Parameters; add this there.

Console:
In an Image Create Task, click on the Advanced button in the lower right on the General tab. Type this into the "Additional options for Ghost command line" field.

Thank you,

Randy

Randy, Ok i see thats pretty

Randy,

Ok i see thats pretty straight forward, so if i just type in "-z9 switch" for example for the highest compression in the command line or the parameters it should compress the file size as small as possible.

Thanks
James

-z9

James,

That is correct. Please note that when you use high levels of compression, you do trade performance speed for saving space. But yes, that will result in the smallest image size possible.

Thank you,

Randy
