Where are AirDrop temp files located? I started a transfer over AirDrop of a 4GB xcode dmg file. Something happened in the middle of the transfer (3.5GB) and I now have 3.5GB of space missing from my computer. I have restarted the computer and deleted the file in the downloads folder. I tried using grand perspective to find large files but I can't seem to find the location of the temporary airdrop file. Where are these temp files located so that I can delete them.
I guess it'd be quite outdated answer, but maybe it will save some time for others

AirDrop temp files hidden under this path /private/var/folders/, you need to look for folder called exactly like this "(A Document Being Saved By sharingd)" in subfolders. 

In my case it was /private/var/folders/fq/51d9_5dn7hg445wwp5n7kyqm0000gn/T/TemporaryItems/(A Document Being Saved By sharingd)
