Only upload one directory at a time

Hello,

Even though I choose many folders, drag them to remote host but SmartFTP only upload one at a time, so I must choose and upload each of folders. I have used many FTP programs, I think I know to use a FTP software.

Regards,

Make sure you use the Transfer Queue instead of Direct Upload and adjust the number of threads per site in the Favorite Settings or Global Settings if needed.
