How do I set all system files to save on separate hard drive?

For Premiere Pro (maybe other Adobe programs) read Drive C space https://forums.adobe.com/thread/2602972

For Windows itself, use the Search bar at the top of http://www.microsoft.com/en-us/default.aspx to find out how to have Windows use something other than the C drive for things like the swap file and other temporary files

Hi,

I understand you are looking for a set up  that would allow essential file like cache, core program files to operate from SSD for a speedy performance and would like to save big size production files on other non SSD with more space.

Here are certain points which I assume would answer your question and would also give you some more content to explore :

1. After windows is installed on a drive, by default all the installed application set up their scratch disk, storage disk on the same Hard Disk unless you to go to preferences of each application and change it to desired one. However, such flexibility varies from one software to other.

2. There are many files an application creates while it runs on a computer and by default it creates on same disc which has OS installed. Example : When you install Photoshop, it will occupy around 1.5 GB space for storing core program related files, approx 0.5-2 Mb in preferences, approx 5-10 GB in caches. All these files are required for speedy performance. While you have flexibility to change cache and scratch disk to other desired drives, you can't change preferences' location. Similarly, you may find different applications exhibiting same more or less same behavior. Basis on space and application , you may decided where to place what and can gauge performance impact before making final decision.

3. There are few applications though which can create problem for you as they create huge amount of data over few minutes of use like premiere pro and after effects. Here if you set cache location to your SSD, no doubt you will get speed but within few minutes, your SSD will be out of space. Here you have to either locate cache to a bigger drive whether SSD or NON SSD basis your budget. This will have a good impact on performance though.

So, to conclude, if you can share list of applications  you will be using, i can probably suggest how precisely can configure your setup for maximum benefits.
