collapse the folder node in the tree [-] -> [+], (move files)

[CompSystems]

hello,

when a file or folder is moved and scanned (directory tree) instead of the destination, if it is inside the same folder, a symbol of NOT ALLOWED (\) appears, a useful idea to implement is to collapse the folder node in the tree [-] -> [+], this improves location speed on directory tree , since when collapsing the current directory it is shown more branches of exploration.
