How to see partially downloaded files via IDM

Here is the default location:-

Code:

 x:\Documents and Settings\username\Application Data\IDM\ 

if you can't find it in there you can view it by clicking "Option--> Save to" in the idm window

ADDED:
btw if it's a "mkv" or "avi" file you can even play them without downloading the whole part by dragging and dropping first part to a media player like "KMplayer"
