mc (the midnight commander) has many options to manipulated file on a Raspberry. Since it is text based it runs well on a Raspberry via ssh. It can however run well on a full blown PC and then show in mc the Raspberries directory. On way for that is using File Transfer over Shell file system. it uses a command as sh://<user>@<Raspberries IP>/home/<path>

On a master PC automount for dome directories on the raspberry can be installed. This way the raspberry will appear in the master PC's file-system under /mnt/auto. This allows to use tools as unison to synchronize the files between both.
