Setting up the Swap drive for PS in Windows

Setting up the Swap drive for PS in Windows

2004-11-23 by Steven Karafyllakis

Ever since PSCS became available and I started working in 16-bit, 
I've had this annoying problem with Win XP when editing large files: 
I have been getting frequent "you are running out of space on swap 
drive D" notices, this in spite of the fact that at one point I had 
a total of 16 GB of swap drives in various configurarions allocated 
to PS. Checking into it I found that only the first two were being 
used, the maximumum file size in either one was 3.99 GB, and the 
notices started as soon as the first partition got to that file 
size. 

I'm sure the more experienced list members recognize the problem, 
but for the sake of Windows newbies, now that I've finally found the 
answer, I'd like to pass it on.

It turns out that the Windows FAT 32 file system won't allow files 
of over 3.99GB, in spite of the fact that it does support really 
large drives. The Windows help utility describes how to use the 
Command Prompt interface to change the swap drive file structure to 
NTFS, which does not have that limitation. 

I haven't seen that pesky notice once since I did the change-over 
yesterday. Yay!

Good tip. Many PS geeks prefer FAT32 because it's somewhat faster. But I
don't find the speed difference particularly noticeable, although I haven't
benchmarked it. If I have to run a benchmark to detect it, then I don't care
about the difference. And now that I do big panos, and have three gigs of
RAM, a 4GB swap file isn't of much use.

How do you use the third gig of RAM since PS will only use two?  Does PS get the whole two gigs and system and other applications go to the third or do you have it configured as the first swap drive?

The remaining gig gets used by the OS, probably mostly for a huge disk
cache, as well as for any other apps that may be open. It means that PS
really really has a full two gigs to run in.

Hi (again!) Paul,

And also, if you have 4GB of RAM it is possible to set up XP Pro (not Home) to
give 3GB to PS and leave the remaining gig for the OS. You need a utility from
the Windows 2000 Server resource kit in order to patch the Photoshop
executable file so it will make use of the available memory, and you also need
to edit the c:\boot.ini file. The following articles tell you what you need to
know:

Thanks. I have XP Pro, and Win2K Server on another machine, so I'll look
into that.
