 Dropbox datastores are limited to 100,000 rows so this is the maximum
 number of files rclone can manage on Dropbox.
 
-Dropbox is case sensitive which can sometimes cause duplicated files.
+Note that Dropbox is case sensitive so you can't have a file called
+"Hello.doc" and one called "hello.doc".
 
 If you use the desktop sync tool and rclone on the same files then the
 md5sums and modification times may get out of sync as far as rclone is

+Frequently Asked Questions
+--------------------------
+
+### Do all cloud storage systems support all rclone commands ###
+
+Yes they do.  All the rclone commands (eg `sync`, `copy` etc) will
+work on all the remote storage systems.
+
+
+### Can rclone sync directly from drive to s3 ###
+
+Rclone can sync between two remote cloud storage systems just fine.
+
+Note that it effectively downloads the file and uploads it again, so
+the node running rclone would need to have lots of bandwidth.
+
+The syncs would be incremental (on a file by file basis).
+
+Eg
+
+   rclone sync drive:Folder s3:bucket
