Up until now i have used exclusively the ISO format for my PE.
It gave me the advantage that the data was accessable in various ways.
Direct boot, RAM boot and running apps like portable software, were the ones i used.

Since a 210MB MiniCD, becomes now a bit too small to house the improved NaughtyPE Core and still leave enough room for apps, i thought about maybe switching to compressed images.

Direct boot and Ram Boot should be no problem. However accessing the contents of the image without booting it first seems more tricky, especialy if it should work without installing software to the host system or requiring Admin rights.

I'm open for all suggestions, also different ways to reduce the needed size on the CD, that i havn't thought of.
Exception is UPXing as this burns 3 times the RAM it saves on the CD.

Use the WimPack script to compress all applications and non-boot-essential system files to WIM images. Much better compression is achieved than having files solely compressed with NTFS compression in the BootSDI image.

Remaining in the .iso field, you can use with RAMDISK booting the .is_ format:
http://www.911cd.net/forums//index.php?showtopic=19737

Otherwise, RAW HD images NTFS compressed are in my view better for three reasons:
1) availability of a number of tools to manage them
2) possibility to use the image DIRECTLY in Qemu or other VM machine supporting RAW HD images
3) everything involved is "kosher"


Why do I have this "deja-vu" feeling? (IMG:../forums/style_emoticons/default/unsure.gif)

As Jaclaz says, you may cab-compress to either .is_ or .im_. The BootSDI script currently supports compressing the ram image and also patching of setupldr so that no additional ram is required as that for uncompressed .img image. The basics could be taken and adjusted to boot .is_ similarly.

Thanks you two for your suggestions and no jaclaz, i hadn't forgotten my post from may.
I'm just hoping that with new developments and new members in the last months, came also a new solution or two. (IMG:../forums/style_emoticons/default/wink.gif)

To make this completely clear, i'm after the tripply crown here, nothing less!
1. running PE straight from CD
2. running PE from RAM to remove the CD
3. using the apps from CD as 'portable apps' in a running Windows

So far most 'compression' solutions kill feature 3.
Putting just the OS in a image and compress it, while leaving the apps plain on CD, would preserve feature 3, but would kill feature 2, if i'm not mistaken.

There is no solution to reduce the needed size on the CD.
And there won't be a solution within first request

Too bad, i was hoping for something like a tool that could give access to the contents of a image without needing to install it.

I've been pondering that problem for quite some time as some might know. (IMG:../forums/style_emoticons/default/thumbdown.gif)

So the only possible way i see at the moment is:
- creating NTFS-compressed PE image
- cabing the image (reduces size by half hopefully)
- use the 'extra' space on the CD to put a second copy of the Apps plain on the CD for 'portable use'

As long as the cabing saves more space, than the extra 'portable' Apps use up, this could be a viable way.

Just so that i get this right.
- NTFS compresses by 20% -30%
- cabing compresses by 50%
So the overall compression is 60% to 65%?
This would put something between 500-600MB on a 200MB MiniCD if it were all image. (IMG:../forums/style_emoticons/default/dubbio.gif)


Does anyone see any fault or has a better solution to the problem?

The fault should be self-evident. (IMG:../forums/style_emoticons/default/w00t.gif)

Compression is NOT something you can add or multiply:
uncompressed source ->NTFS compression may give 30% compression
uncompressed source ->CAB compression may give 50% compression

You cannot expect that a 70% compressed NTFS becomes 35% with CAB compression.
