For the last couple of days, I've been downloading an `.exe` file; its size is about *1.73 GB*. The **TEMP** folder was on `E:\`. When it's done, IDM merged about *1.5 GB*
 and gave me an error about no free space were left on `C:\` where the **OUTPUT** folder was located. 

I freed up some space and resumed the process again. But it stuck in the middle and barely moved. So I cancelled it and retried. It then jumped to full par and stuck there. I force-closed it again. But the next time I resumed the download it went back to *15%*, meaning that it discarded about *1.5 GB* data. 

But fortunately that part was merged in the **OUTPUT** folder. So I took the remaining *230 MB* part and put them together. Hoping that I might find a way to merge them and spare me the download again. Note that the whole program is fully downloaded but separated in two parts. I am using *Win 8*.
