Flash takes me a lot of hardisk space

Hello, at first, sorry for my English

And now my problem. I have a flash application which runs locally on the computer in the stand alone adobe flash player. In my application, I load some photos and videos dynamically and I am using XML and so on. When my application is running some hours, I noticed, that it takes a lot of space on my hardisk. Even if I am not working with application, it takes space. I don´t know where this application stores the data and for what reason, but I must stop it, can you help me? The mistake might be in my code, what can do this? Do you have some experience with this?
