If you have an SSD for C: and you want to get PD to put its temporary files, etc., on another drive you can redirect a folder. For example, PD puts its temporary files in C:\Users\xxxx\AppData\Roaming\CyberLink\PowerDirector\10.0. If your SSD is cramped, you can have Windows redirect the actual location of that folder.
This is from the Windows 7 Help system. (Search for "redirect folder.")
Redirect a folder to a new location
You can change the location of the folders in your personal folder (such as My Documents and My Pictures) by redirecting them. For example, if you have a large number of files in your My Documents folder, you might want to store the files on a different hard drive or on a network to free up space on your primary hard drive.
When you redirect a folder to a new location, you change where the folder, as well as the files in the folder, are stored. However, you'll still be able to access the folder the same way you did before you redirected it.
To redirect a folder to a new location
Click the Start button , and then click your user name.
Right-click the folder that you want to redirect, and then click Properties.
Click the Location tab, and then click Move.
Browse to the location where you want to redirect this folder. You can select another location on this computer, another drive attached to this computer, or another computer on the network. To find a network location, type two backslashes (\\) into the address bar followed by the name of the location where you want to redirect the folder (for example, \\mylaptop), and then press Enter.
Click the folder where you want to store the files, click Select Folder, and then click OK.
In the dialog that appears, click Yes to move all the files to the new location.

Note: If you don't see the Location tab in a folder's Properties dialog, then the folder can't be redirected. If you see the Location tab but can't edit the folder path, then you don't have permission to redirect the folder.

This can get you out of a jam caused by lack of space on your C: partition, whether it's an SSD or regular hard drive. Obviously, the SSD is going to be faster; but slower is better than not working. Jerry Schwartz
