ed,

you can not imagine how that encourages me, to think i knew a computer answer. i can't believe it.

another thing i wondered about, don't know if this is mac-specific, but i think it doesn't happen in ps6, but does in 5 and 5.5 on macs, is automatic creation of "photoshop temp" files, which are invisible and huge and must eat up a lot of space. don't know what they're for, but now i reg. search for them "photoshop temp" and delete 'em

imagine that. imagine that. i am so pleased.

Hey, turnabout's fair play. You made my day, and I made yours. I didn't find any temp files for Photoshop, so I don't know if it's Mac specific or not. Could be, I guess.

Sounds like this is the "Guru" thread. Learning as we go, I like that.

All modern operating systems use a 'scratch disk' (aka: 'virtual memory'). If you don't specify a separate hd for Photoshop to use it simply uses the default virtual memory area.

If you have 2 or more physical hard drives you can assign both virtual memory and PS scratch disk to the 2nd (ie: the non-booting hd). If you're uncomfortable foraging around in your OS's innards, I'd suggest simply pointing PS to the 2nd hd.

This assumes a few things:
That your 2nd hd is fast and modern (as recently as 3 years ago hd speed increased enormously, and speeds up with every generation).
That your OS and PS are on your boot drive (the idea is to separate your scratch area from your program area, doesn't do a lot if you just move them together).

Most ppl should simply leave the defaults. Some go so far as to use a utility to permanently commit a section (or 'partition') of a hd for virtual memory/scratch use, but we're talking serious techie here.

If you're really bothered by the reminder that you're not running at 100% (no one does) just click on the little right-pointing arrow next to that area and select a different display (I personally think the file sizes are a lot more relevant to display)

Ed,

At least you've got the consolation that your PC doesn't run on petrol or diesel then you'd only be on 10% efficiency.

Did you do full defrag, how long to do it as regards time v disc capacity ?

When I defrag the drives its a case of letting the machine do it overnight.

Kathleen & Ed,

Photoshop definitely creates temp files on PCs - and they get VERY big!! Sometimes (I think when my computer crashes), they don't get cleaned up and I have to manually delete them. On my PC they're located in: Windows/Temp. You can't miss them if you sort the files by file size.

Thanks for all the replies. I wasn't aware that there more posts here. For some reason, I seem to be missing some of the new posts.

Chris,
I don't know how long it really takes, as I just do defrag overnight too.

Jeanie,
Thanks for the info. I'll have to check out my temp files there.

Doug,
I really never look at the efficiency. I guess that's why it bothered me when I saw it. Like you, I think the file size is more meaningful. Thanks for the lesson.

Ed

Ed, I think if you copy (and paste) a large file, it stays in the clipboard until you copy something else or quit PS therefore taking up that much ram that you can't use. You can gain that ram back by selecting a small area and copying,therefore pushing the large file out of the clipboard (thats what I read somewhere a long time ago and wish I could remember it when I'm working ).

Roger,

I knew that something copied would stay on the clipboard, but I thought that after you pasted it, it would be cleared. Thanks for straightening me out on that. I'll try to remember that one.

Ed

Go into your edit options (same place you assigned your avatar) and look for the thread options and choose show all threads. That will help so you don't miss them.
