Hello Oleg,
I have a simple task which copies all files from a webserver to the local drive of Robotask. However, the copy job only copies 1 folder with no content. And there are files in there. The task keeps running till eternity.
When I do the same copy job by hand in Windows (same account, same PC), the copy is finished errorless within seconds.
Here you can see the content. Left the target folder, right the source. As you can see: a lot of folders and files. The only folder which is copied by Robotask is "App_data" with no files.

The task itself:

Final result:

Even deleting the job, and create a brand new one doesn't help. Also you can see I avoided the usage of variables to rule out that cause. And even that....doesn't help.
What can it be?
