If you have multiple folders to transfer (recursively) with files in each folder and transfer them, all folders are created and all files are transferred except the files within the last folder.
Folders and files to be transferred:
Whilst in the root folder containing Folder1, Folder2 & Folder3, <shift>select all 3 folders and drag to the destination.
This is running on Windows XP BTW. It would also be nice to enable you to select files and folders to transfer by dragging a box areound the files/folders (standard windows navigation). You can only select multiple files by <shift> click or <ctrl> click.
FTP Rush creates folder1 2 & 3 and transfers File1.txt and File2.txt but NOT File3.txt.
You have to remember to re-transfer File3.txt. This is annoying as if you forget to do this and then delete your source folders/files you lose the contents of Folder3!
