Where does Transmit 4 store temporary downloaded files?

Question

If you have two remote locations in Transmit 4, say an S3 and an FTP location, and you move a file between these two locations, Transmit will automatically download that file, and then upload it.

Where does Transmit 4 store these temporary files?

Answer 1

You can find this out by yourself:

1. Start Transmit
2. Execute sudo opensnoop -n Transmit in Terminal
3. Initiate transfer from S3 to FTP

This will list all created/opened files, it shouldn't be difficult to identify the temporary files.
