IFW 2.97e Compression

Post by AlanD »

Just looking at "Show Command" after walking through setup in IFW 2.97e,
"comp:14" no longer is shown as part of the command line when selecting
enhanced speed A.

Is that option now considered de-facto, no longer needing to be a part
of the command line?

it's the default so not needed.

Good day.

I know, I'm annoying with my questions, sorry!

So I'm hijacking this thread because the subject fits :-) Can someone explain these compression options a little? The best compression I assume is "Enhanced Size F" ? How does "Enhanced Speed A/B" compare to "Standard", are they even faster? I'm looking to equate the compression I get with Ghost set to "High" without having to do 7 images, time them, and then compare the size I get. With Ghost, the maximum (which you can only get via command line switch) is just not worth it, but "High" is (for me anyway).

Thanks for any advice you can give me regarding compression.

Just use the default (enhanced speed A). The enhanced size options are
much slower and the gain typically isn't worth the time (the B/C E/F options
take much longer than A and D but don't save much of anything).

Good day.

Well I ended-up testing a few options anyway. For those wondering, here are my results:
60G Windows partition with 30G of data, with lots of highly-compressible files already NTFS-Compressed.
Images created with Win 8.1 Update 1 PE disk, on a USB3 external drive.

Speed-A, 12 minutes, 21.5GB.
Speed-B, 20 minutes, 21.0GB.
Size-A, 37 minutes, 18.7GB.
Size-B, 53 minutes, 18.3GB.
Size-C, > 1Hr, 18.3GB.

For reference, Ghost @ High takes 40 minutes and produces a 19.3GB file, roughly the same as IFW Size-A setting (with IFW beating it a little). The surprise are the Enhanced Speed options; for the size you get, the speed is impressive!

On some computers IFL can be faster than IFW.
It will run from a CD, DVD or flash drives for
Windows users.

I download the IFL CUI & GUI's w/networking.

Why not remove them?
