Ok after I have worked on something like a 600mb file and close it photoshop still holds about 1.5gig of memory dispite closing the image. Its only upon closing photoshop it is released.

Is there any support for allowing the memory to be dumped after closing a file because its really affecting the overall performance of the computer

Got 4 gig of ram
an 8 gig usb stick as readyboost
320 usb hdd as scratch disk

windows 7
 
Readyboost isn't going to aid your system IO when you've got >4GB RAM really. I'd recommend a wiser solution and that is to get an additional 4GB of RAM which will greatly improve the performance of your OS under the usage pattern you've described.

It's also very quick to close + re-open Photoshop though, maybe takes 3 seconds max on a HDD unless Windows has switched to your pagefile because of all your RAM being utilised and so everything slows a bit.

In which case more RAM :)

This isn't a bad shout and for £28 to boost it up to 8gb, Well worth the extra 30quid pal.
 
If it's running a 64bit OS and the mobo supports +4GB then yes but if you're on 4GB now then I'd imagine the answer is yes anyway but via 2x4GB modules which I can't imagine are cheap though!

Its a Dell Laptop. Can it have 8Gig of ram?

Also purge isn't doing anything to help.

Is the problem solved by closing and re-opening Photoshop? Because all Purge / All does is basically the same thing but keeps PS open. Is the scratch drive the same as the OS drive? And is that running close to capacity? When working on large files the temp files stored on the scratch drive can increase scarily quickly, and if it's on the same drive as the OS it will lead to system instability. These are supposed to self delete whenever Photoshop is restarted but sometimes won't.

If it's really affecting general system performance you can always limit the amount of RAM Photoshop can have in Edit / Preferences / Performance. Maybe limit this to 60% so you don't find it taking over your machine. But then Photoshop will only have to hit the scratch disk more to store temp files, which if that's your OS disk will slow the system (another reason among many why you should really always have a separate scratch disk for PS).

Photoshops general memory management will refrain from constantly flushing the memory every time you close an image because it's quicker when you start working on the next image if the memory is already assigned to Photoshop. If the OS really needs it it will hand it over, but generally speaking it's more efficient to keep it (Like superfetch, if nothing else needs it it'l keep programs pre-loaded, unused memory is wasted memory after all).

You are dealing with quite a sizeable file for 4GB of ram and a single disk, so you could just be at the limitation of the machine.
