Hello All,  
I just installed FormBuilder, and it's going great so far. Great time saver! I spent a couple of days doing a file upload form manually and was able to recreate it within minutes in FormBuilder. 
Quick question about the general file upload functionality in PW: 
When I was doing a file upload manually, I set the upload destination, and the file would upload there, but would also be in the assets/files area in a folder matching the entry ID. Now that I'm using FormBuilder, I stuck with the default upload area for FormBuilder, assets/cache/form-builder. I still get the same result though. The uploaded file ends up in assets/cache/form-builder, as well as in the assets/files/{entry_id}. Is this normal? When I view the entry itself, it's linked to the assets/files folder.  
So, what's happening seems independent of FormBuilder. Sorry if I am not fully understanding something about how files are dealt with in PW. I tried to find more info on how file uploads work in PW but I still don't fully understand it.  
Thanks for any info you can provide.
