this is about an article that i've read. I'm using photoshop7 and as usual base on the article that i've read, it says there that ps7 or any other version of photoshop uses a ram memory space and whenever it cannot find enough ram memory it'll use your hard disk. what will be the common problem who hasn't have enough ram memory or who has only a small ram memory left, will that make photoshop work slowly? what if photoshop had already use your hard disk as a scratch, will i have a lesser space even i turned off photoshop?

oooh lots of questions,

will be the common problem who hasn't have enough ram memory or who has only a small ram memory left, will that make photoshop work slowly?

you've answered your own querstion there - less ram means PS will ahve to do more work with the scratch disk which will run much more slowly.

what if photoshop had already use your hard disk as a scratch, will i have a lesser space even i turned off photoshop?

not sure I fully understand the question. Photoshop uses the scratch disk as an overflow for when all the ram is taken up (actually thats a gross over simplification). The more ram you have, the less the sratchdisk will be used. When photoshop is not running the scratch disk vanishes and is recreated next time you start the program.

To help PS run faster you can either add more RAM (anything less than 256mb is going to cause major slowdowns). you can also put your scratch disk on a totally seperate hard drive to your windows swap file (page file?) note this has to be an actual hard disk and NOT a partition.

Hope this helps
