Question Deleting Application Data

[Columbia42]

I was cleaning out my hard drive contents the other day and I happened to notice a staggering amount of application data that had been created by a program. Over the one and a half years I have been using this program it has accumulated 40 GBs of data. Is there anything I can do with all this stuff? The primary hard drive on my computer is only 60GB so this is a sizeable portion of storage space.

That depends on the program which stored that data. What program stored so much data?

It's a video editing program called Pinnacle Studio. The data is generated when I export a video project as a file such as an AVI. Apparently writing the file is what generates the data. In my experience with other video editing programs this data is supposed to be deleted when the export process is finished.

The data there is probably cached for subsequent edits (i.e. when you save the video, exit, but then you go back to make some changes). From what I found on Internet, they are called "auxiliary files", they can take much space, and they aren't deleted after use. There is "Delete Auxiliary files" command in "File" menu of Pinnacle Studio, which removes these intermediate files, when you don't need them any longer.
