When using a copy file task to copy a folder to a targeted computer, only the files are copied to the destination folder. The Source folder is not created on the destination computer.
Steps to reproduce
Create a folder with one or more files inside and share the folder
Create a Deployment Solution Copy File task
Choose Copy folder radio button with Source set to Access from UNC location
Enter credentials as needed to access source folder
Enter a destination folder
Run task against a test computer
Note that only files are loaded into the destination folder specified – the source folder selected is not copied. In RU3, this source folder is created in the destination folder along with any files from the source folder.
