Hi,
Usually that means you've set the path incorrectly in the task. What error do you get if you use the Connection explorer (in Tools) and try to download the file from there?

The path is correct. Other files are downloaded correctly some files like this one runs on error.

From Connection Explorer:


FIle was downloaded but with 0KB. Original File is 144KB

Hi,

Could you try go to Extra settings, and set the "Pipeline length" to 1 and see if that makes a difference? If not - try also setting Upload block size to 32256

After activating "Auto Adjust transfer block", file can be downloaded without problem.
