Samples Duplicated with Program files

So, I'm doing some file cleanup and organizing via USB on the computer. I noticed that all of the samples I use in a program are duplicated from their normal folders into my programs folder along with the program files. Is there a reason for this, or is this something I did inadvertently?

Can I delete them? It seems redundant and a waste of space. I feel like a program should be able to recall the file and load it into the RAM without having a duplicate saved along with it.

how much disk space are ya workin with?

I've got a 100GB hard drive. Lots of room.

thats plenty of room. i wouldnt worry about it.

Bahaha alright. Thanks.
