where is my free space

I'm using Pinnacle Studio 12 to edit some videos and as you can guess it uses a lot of resources. The problem is that it eats all my free space from the C drive and after I close the application I don't get back my free space. I assume it does swap some files but where and why it doesn't delete them?

I don't store the project and saved files on C drive. I'm running Pinnacle Studio 12 on a XP sp3 Windows machine. I've tried to clean my system with CClean, but it doesn't find/see where my space is lost!

TY

Have you manually checked the following folders?

C:\Documents and Settings\Home\Local Settings\Application Data\Pinnacle Studio
C:\Program Files\Common Files\Pinnacle Studio
C:\Documents and Settings\All Users\Application Data\Pinnacle Studio
C:\Program Files\Pinnacle Studio

You can also find other programs to visualize disk space at this other question.

I don't have access to Pinnacle that new but in Pinnacle 9 all the intermediate and temporary files are saved in %HOMEPATH%\Pinnacle Studio\Auxiliary Files\<project filename>\.

If that yields no results, I'd try the Windows' default temporary file locations: %TEMP% and %WINDIR%\Temp\.
