You aren't really correcting the post, but simply rewording it.
No, I'm correcting an incorrect statement, as I'll also do below.
Each drive in windows has it's own swap file.
Wrong. Each drive *can* have it's own windows swap file. I have attached my current allocation below. As you will see, I use a single swap file on one drive, which happens to be the default of C: in this case (just a workstation).
By default windows is always installed on a the C Drive.
Wrong. *Most* of the time, people *choose* to install to the C: drive, if they even have the choice available. Many people partition their drive during windows install, or use multiple drives, and install windows to a drive other than C:. Drive letters are set by the BIOS and the physical drive arraingment, not software.
I believe I stated you don't want CS2's scratch on the same drive as windows virtual memory namely the C Drive.
You believe incorrectly, read your original post:
It's a common recommendation that the drives be independent of where your CS2 software is located on a windows machine most commonly your C Drive.
The only separation is between the swap files. It has nothing to do with where windows is installed or where PS is installed.
And yes you are separting the CS2 Scratch and windows which is on the C drive. I don't know a way to pull the paging file for drive C which is the paging file for the OS, off of C and move it to another drive and still have windows OS see it. If you do it's way beyond this discussion.
Obviously you are a windows newbie, I don't even need to point out how wrong that statement is, but it does explain why you are wrong on every single one of your other points. See my screenshot below for where to change your swap file. Control Panel, System, Advanced, Settings, Advanced.
Not sure why the point of "correcting" my post was necessary.
Because everything you said was wrong, how's that for a good reason?
