Using your method (A string asFileReference) it works thanks !

But if you use FileSystem root / .... I get the "same" object but it's still not working. Did I make a mistake somewhere?

Seems to work OK for me (Pharo 5 on Mac OS)

'/tmp/foo.txt' asFileReference writeStreamDo: [ :out | out << 'Pharo' ].

'/tmp/foo.txt' asFileReference exists.

'/tmp/foo.txt' asFileReference renameTo: 'bar.txt'.

'/tmp/foo.txt' asFileReference exists.

'/tmp/bar.txt' asFileReference exists.

'/tmp/bar.txt' asFileReference contents.

Maybe a permission problem ?
