in my 55.7 GB C: partition. That's on a system with 16 GB of RAM.
Three keys: 1) Data and caches and temporary files are on another disk. 2) I eliminate hiberfil.sys ("powercfg /hibernate off"); and 3) I moved pagefile.sys to another disk.
I set my C partition so small with an eye to the future so I could clone the OS to a pair of 60 GB SSDs running in a RAID 0 configuration for performance. Based on this I could run a triplet of striped 40 GB SSDs for triple speed. You don't want to thrash an SSD with a page file. Pagefile and hiberfil are about the size of RAM, so I save 28 GB of C: partition space with key 2 and 3 above.
Do this, leisurely,
on a case by case basis, step by step, until you are ready:
1) Use microsofts Disk Management to shrink the C partition on your 1 TB drive some and then use diskpart to allocate the free space as two partitions.
2) Label the two partitions Data and Cache and assign drive letters to them, like D and E.
3) From time to time move some of your data into Data and make any appropriate links as needed (media libraries, WinAmp playlists, etc.).
4) When you run a program, take a few minutes to point its temporary files and cache files to subfolders in the Cache directory.
5) The goal is to get Data and Cache as big as you can. So every so often, shrink the C partition some and grow the Data partition with most of the new space and grow the Cache partition a little.
This way you can squeeze your C partition
over time without trying to do in a single huge period of time.
When you have your C partition squeezed down to an affordable size of SSD, pull the trigger to obtain it, and clone it to the SSD. You'll be able to do that confidently and quickly and efficiently.
Always backup your files including the OS and system files so that they always exist in three copies (three drives) with one off-site.
