The File class binds a lot of the POSIX API. Let's start with "move" here.


st> 'oldName' asFile renameTo: 'newFile'

will move/rename 'oldName' to 'newFile'

For copying I think you would need to do something like:


| outStr |
outStr := 'newFileName' asFile writeStream.
'oldFile' asFile readStream nextPutAllOn: outStr.
outStr close.

A writeStreamDo: might make sense to have the close be called as well. In File 
we have bindings for fsync and fdatasync as well in case you really want to 
control the consistency.
