Question by ~princesss~: how do i upgrade/update [only] photoshop CS2 to CS4-just like convert only with all the files still in it?
i want to have adobe photoshop cs4. but i don’t want to waste my time transferring all those files i have in CS2. is there anyway to JUST convert/upgrade/update my CS2 to CS4? any sites that offer free trials?

it has to be that when i run my CS4, all my files at CS2 are automatically in it.

No problem. Going from CS2 to CS4 will not wipe out your files. Your files will not be effected as they are, most likely, in folders outside of CS2. Only if you have downloaded a bunch of plugins, brushes, styles, etc. and placed then in with those that came with CS2 are you likely to lose anything. It is better to place those things in their separate folder and with Preferences, point PS to that folder.

There is no “upgrade” to a higher version of PS. Each version is a standalone program. I have five versions of Elements and two versions of PS installed on the same compujter and have never lost anything.

maybe you opened the original file, and changed the name of the one you were working on.
