Hiya,
Just wondering ... I have a PS file that has 6 layers, each layer with a few effects added. This file is a whopping 39 MB! The second one I have is similiar and is 26 MB.
I have it set at 8.50 x 11 ... full size sheet. I have allot of RAM, allot of disk space, and a really fast CPU .. just upgraded everything, but STILL it takes forever to move items, apply effects and save things working with this document.
My question: is there any way to make this file smaller ... well, I know I can reduce the resolution, or size .. but won't that compromise the quality of the final output, as in printing?
Thanks!

Instead of trying to reduce the file size I'd be more inclined to discover why your PC with "lots of RAM" and a "really fast CPU" can't handle a small file like yours.
I frequently work with 150 MB files on a workstation with a P4, 3.0 GHz CPU and 1,000 MB of RAM. Your files should be a breeze on such a PC.
If you shut down the browse function of CS after you've loaded your image(s), you can work faster but the real thing is to buy a separate, well cached hard drive to use as a swap file for Photoshop. A 'J' series WD drive is good.
Your problem sounds to me as if you have the swap file (scratch disk) on the same volume as Windows and PS. This can reduce the speed you can work at quite substantially.
If you don't feel like spending on a new drive, re-partition your existing one to give you 2 extra virtual drives. One of about 5 gig. Set PS to use that drive as it's scratch disk and don't limit the size of it.
Set Windows to use the other drive as it's swap file (virtual memory) and fix the size of (Windows) swap file on the primary drive to 64 meg and the new swap file to 4095 Meg on the remaining drive. You won't see much performance improvement (if any) until you start using files over 20 meg in size in Photoshop but these setting will increase the ability of PS to handle Microsoft's memory paging method of accessing a lot of RAM.
On the more Technical front... Windows doesn't have an absolute limit on how much memory it or programs running under it can use. Instead it uses a method of dumping memory contents to the hard drive (a swap file) so it can free up whatever RAM it has for priority tasks.
Window begins to swap out it's RAM contents long before it fills available RAM and it is this process which slows down the computer. By fixing the swap file size, Windows doesn't have to thrash all over the drive looking for fragments it can place as it swaps data back and forth. The same goes for Photoshop in spades.
When you put both swap files on the same drive as the program, the system spends a lot of time thrashing around on the drive looking for where it can place data. Stop that from happening and the whole thing will go a lot faster. The file browser of CS is a real speed hog. Shut it down or don't use it at all and your system will run faster.
