Moves the contents of the source directory to the destination
directory. Rclone will error if the source and destination overlap and
the remote does not support a server side directory move operation.

If no filters are in use and if possible this will server side move
` + "`source:path`" + ` into ` + "`dest:path`" + `. After this ` + "`source:path`" + ` will no
longer longer exist.

Otherwise for each file in ` + "`source:path`" + ` selected by the filters (if
any) this will move it into ` + "`dest:path`" + `.  If possible a server side
move will be used, otherwise it will copy it (server side if possible)
into ` + "`dest:path`" + ` then delete the original (if no errors on copy) in

**Important**: Since this can cause data loss, test first with the

Eg delete all files bigger than 100MBytes

Check what would be deleted first (use either)

    rclone --min-size 100M lsl remote:path
    rclone --dry-run --min-size 100M delete remote:path

Then delete

    rclone --min-size 100M delete remote:path

That reads "delete everything with a minimum size of 100 MB", hence
delete all files bigger than 100MBytes.

So

    rclone copyto src dst

where src and dst are rclone paths, either remote:path or
/path/to/local or C:\windows\path\if\on\windows.

This will:

    if src is file
        copy it to dst, overwriting an existing file if it exists
    if src is directory
        copy it to dst, overwriting existing files if they exist
        see copy command for full details

This doesn't transfer unchanged files, testing by size and
modification time or MD5SUM.  It doesn't delete files from the
destination.

Note that files in the destination won't be deleted if there were any
errors at any point.

It is always the contents of the directory that is synced, not the
directory so when source:path is a directory, it's the contents of
source:path that are copied, not the directory name and contents.  See
extended explanation in the ` + "`" + `copy` + "`" + ` command above if unsure.

If dest:path doesn't exist, it is created and the source:path contents
go there.

If you are familiar with ` + "`" + `rsync` + "`" + `, rclone always works as if you had
written a trailing / - meaning "copy the contents of this directory".
This applies to all commands and whether you are talking about the
source or destination.

See the ` + "`" + `--no-traverse` + "`" + ` option for controlling whether rclone lists
the destination directory or not.
