I'm seeing strange behavior when downloading very large files.
I have just had to cancel a download of a 3GB file after a temporary file on the OS partition, not the selected destination partition, exceeded the available free space at 700MB.
 
What is Firefox doing in this temp file (a buffer?), the download seems to be being written directly to the requested destination?

The file would also seem to be in the wrong place as you would expect it to be on the drive selected for the download if it needs to be large.

Reproducible: Always

Steps to Reproduce:
1. Start large download to a different partition (say Z:) than the OS partition (say C:).
Actual Results:  
Observe that a file is created on Z: and that it grows as the download progresses.

Observe that a temporary file (in the form "IHxxx.tmp") is also created in "C:\Documents and Settings\<username>\Local Settings\Temp" and that this file also grows but is approximately equal to half the size of the 'real' file on Z:

Expected Results:  
The very large temporary file should not be created, or should be on the drive specified for the download.
