File Cache Location

[rossputin]

Hi Guys.

Relatively inexperienced in terms of OS X knowledge file and memory systems here. I am writing a large number of files (PDF's around 12 Meg) in my app. As I do so I notice the free memory listed in 'Activity Monitor' shrinking rapidly. When I exit my app, it frees up its own memory. However, the files created retain their memory. The only way to free the memory up is either to delete the files, or restart my machine. What I am looking for is a way to delete the cache for the files, so I can keep the files, but free the memory. Or perhaps their is a setting for writing the files so a cache will not be created? I am using a Java app to produce the files.

Thanks in advance for your help.
