Cannot move folders (O365)

[germain-italic]

Hi!
First of all happy new year, and congratulations for your software.

I have an Office 365 Premium subscription with SharePoint (plan 1) activated. On the main teamsite I have created a Documents repository, which contains 133 folders. I am running SPFileZilla under Windows 10 Professional.

I'm trying to move folder A into folder B. My steps are:

• Right-click on B and select "Copy path to clipboard"
• Right-click on A and select "SharePoint only operations > Move files"
• Paste the path
  • I have tried as is, including the domain name
  • I have tried without the domain name (destination starting with /)

Unfortunately I always got the following message:

17:45:07: Loading List Root Folder Contents... (Max files returned: 500)
17:45:09: 133 Folder(s)/File(s) Loaded Successfully
17:45:22: Folder Copied Successfully: AFD

Drag'n'drop works on the SharePoint default AllItems listview, thought.

Any idea?
